I'm trying to customise this Angular Material example code (https://material.angularjs.org/latest/api/directive/mdSelect) to my needs.
I have three groups of select options. If an option is selected in a group, it should unselect all options in other groups (but leave other options in own group as they are).
In my code I have managed to get the logic working right (as you will see from the console.log outputs at the bottom), but the actual select options do not interact with user input.
My JSFiddle: https://jsfiddle.net/e2LLLxnb/8/
My JS code:
var myModule = angular.module('BlankApp', ['ngMaterial']);
myModule.controller("FilterCtrl", function($scope, $element) {
$scope.categories = ["Any", "Target Category", "Option 1", "Option 2", "Option 3", "Option 4"];
$scope.mustCatSelected;
$scope.categoryObj = {};
// build the list of options with values and groups - create equivalent of $scope.data for <md-option ng-repeat="item in categoryObj.data.items">
var finGroup = [];
$scope.categories.forEach(function(value,key){
if(key>1){
finGroup.push(key);
};
});
$scope.categoryObj.data = {items: [], groups: [{
group: [0]
}, {
group: [1]
}, {
group: finGroup
}]};
$scope.categories.forEach(function(value,key){
$scope.categoryObj.data.items.push({name: value,
value: false,
id: (key + 1)});
});
$scope.clickOn = function(item, index) {
if(item.value == false){item.value = item.name;}
else {item.value = false;}
if (item.value === false) {
} else {
var thisGroup = [];
angular.forEach($scope.categoryObj.data.groups, function(value, key) {
if (value.group.indexOf(index) !== -1) {
thisGroup = value.group;
}
});
angular.forEach($scope.categoryObj.data.items, function(value, key) {
if (thisGroup.indexOf(key) !== -1) {
return;
} else {
value.value = false;
}
});
$scope.mustCatSelected = $scope.categoryObj.data.items.filter(function(e){
return e.value != false;
});
console.log($scope.mustCatSelected);
console.log($scope.categoryObj.data.items);
}
}
//search-term header
$scope.searchTerm;
$scope.clearSearchTerm = function() {
$scope.searchTerm = '';
};
// The md-select directive eats keydown events for some quick select
// logic. Since we have a search input here, we don't need that logic.
$element.find('input').on('keydown', function(ev) {
ev.stopPropagation();
});
});
Solved (finally!): https://jsfiddle.net/hqck87t1/4/
var myModule = angular.module('BlankApp', ['ngMaterial']);
myModule.controller("FilterCtrl", function($scope, $element) {
$scope.categories = ["Any", "None", "Option 1", "Option 2", "Option 3", "Option 4"];
$scope.mustCatSelected = [];
$scope.categoryObj = {};
$scope.categoryObj.items = [];
$scope.categories.forEach(function(value,key){
var grp;
if (key < 2){grp = key;}
if (key >= 2){grp = 2;}
$scope.categoryObj.items.push({
name: value,
id: (key + 1),
group: grp});
});
//set default
$scope.mustCatSelected.push($scope.categoryObj.items[0]);
$scope.clickOn = clickOn;
function clickOn(newValue, oldValue, type) {
//console.log($scope.categoryObj.items);
//console.log(oldValue);
if(oldValue.length == 0) {
return false;
}
//create arrays of new and old option ids
oldValue = JSON.parse(oldValue);
var newIds = [];
var oldIds = [];
newValue.forEach(function(value,key){
newIds.push(value.id);
});
oldValue.forEach(function(value,key){
oldIds.push(value.id);
});
//define and set the clicked value
var clickedValue;
newIds.forEach(function(value, key){
if(oldIds.indexOf(value) == -1) {
clickedValue = value;
}
});
var clickedGroup;
newValue.forEach(function(value,key){
if(value.id == clickedValue){
clickedGroup = value.group;
}
});
//console.log([clickedValue, clickedGroup]);
//console.log([newIds, oldIds, clickedValue]);
if(type == 'mustCat'){
$scope.mustCatSelected = $scope.mustCatSelected.filter(function(e){
return e.group == clickedGroup;
});
}
}
//search term above select
$scope.searchTerm;
$scope.clearSearchTerm = function() {
$scope.searchTerm = '';
};
// The md-select directive eats keydown events for some quick select
// logic. Since we have a search input here, we don't need that logic.
$element.find('input').on('keydown', function(ev) {
ev.stopPropagation();
});
});
There key to the solution lies in two things:
Using ng-change instead of ng-click. The former is used to distinguish the state of ng-model inline vs the specified state of ng-model after the change event. Whereas ng-click is not reliable for this.
Write the ng-change function in the html like this:
ng-change="clickOn(mustCatSelected, '{{mustCatSelected}}')"
where mustCatSelected is the ng-model and '{{mustCatSelected}}' the inline state of ng-model before the change event.
Now we have an multiple md-select with logic handling the selection of options / groups of options.
I want to use the filter in angular and want to filter for multiple values, if it has either one of the values then it should be displayed.
I have for example this structure:
An object movie which has the property genres and I want to filter for Action and Comedy.
I know I can do filter:({genres: 'Action'} || {genres: 'Comedy'}), but what to do if I want to filter it dynamically. E.g. filter: variableX
How do I set variableX in the $scope, when I have an array of the genres I have to filter?
I could construct it as a string and then do an eval() but I don't want to use eval()...
I would just create a custom filter. They are not that hard.
angular.module('myFilters', []).
filter('bygenre', function() {
return function(movies,genres) {
var out = [];
// Filter logic here, adding matches to the out var.
return out;
}
});
template:
<h1>Movies</h1>
<div ng-init="movies = [
{title:'Man on the Moon', genre:'action'},
{title:'Meet the Robinsons', genre:'family'},
{title:'Sphere', genre:'action'}
];" />
<input type="checkbox" ng-model="genrefilters.action" />Action
<br />
<input type="checkbox" ng-model="genrefilters.family" />Family
<br />{{genrefilters.action}}::{{genrefilters.family}}
<ul>
<li ng-repeat="movie in movies | bygenre:genrefilters">{{movie.title}}: {{movie.genre}}</li>
</ul>
Edit here is the link: Creating Angular Filters
UPDATE: Here is a fiddle that has an exact demo of my suggestion.
You can use a controller function to filter.
function MoviesCtrl($scope) {
$scope.movies = [{name:'Shrek', genre:'Comedy'},
{name:'Die Hard', genre:'Action'},
{name:'The Godfather', genre:'Drama'}];
$scope.selectedGenres = ['Action','Drama'];
$scope.filterByGenres = function(movie) {
return ($scope.selectedGenres.indexOf(movie.genre) !== -1);
};
}
HTML:
<div ng-controller="MoviesCtrl">
<ul>
<li ng-repeat="movie in movies | filter:filterByGenres">
{{ movie.name }} {{ movie.genre }}
</li>
</ul>
</div>
Creating a custom filter might be overkill here, you can just pass in a custom comparator, if you have the multiples values like:
$scope.selectedGenres = "Action, Drama";
$scope.containsComparator = function(expected, actual){
return actual.indexOf(expected) > -1;
};
then in the filter:
filter:{name:selectedGenres}:containsComparator
Here is the implementation of custom filter, which will filter the data using array of values.It will support multiple key object with both array and single value of keys. As mentioned inangularJS API AngularJS filter Doc supports multiple key filter with single value, but below custom filter will support same feature as angularJS and also supports array of values and combination of both array and single value of keys.Please find the code snippet below,
myApp.filter('filterMultiple',['$filter',function ($filter) {
return function (items, keyObj) {
var filterObj = {
data:items,
filteredData:[],
applyFilter : function(obj,key){
var fData = [];
if (this.filteredData.length == 0)
this.filteredData = this.data;
if (obj){
var fObj = {};
if (!angular.isArray(obj)){
fObj[key] = obj;
fData = fData.concat($filter('filter')(this.filteredData,fObj));
} else if (angular.isArray(obj)){
if (obj.length > 0){
for (var i=0;i<obj.length;i++){
if (angular.isDefined(obj[i])){
fObj[key] = obj[i];
fData = fData.concat($filter('filter')(this.filteredData,fObj));
}
}
}
}
if (fData.length > 0){
this.filteredData = fData;
}
}
}
};
if (keyObj){
angular.forEach(keyObj,function(obj,key){
filterObj.applyFilter(obj,key);
});
}
return filterObj.filteredData;
}
}]);
Usage:
arrayOfObjectswithKeys | filterMultiple:{key1:['value1','value2','value3',...etc],key2:'value4',key3:[value5,value6,...etc]}
Here is a fiddle example with implementation of above "filterMutiple" custom filter.
:::Fiddle Example:::
If you want to filter on Array of Objects then you can give
filter:({genres: 'Action', key :value }.
Individual property will be filtered by particular filter given for that property.
But if you wanted to something like filter by individual Property and filter globally for all properties then you can do something like this.
<tr ng-repeat="supp in $data | filter : filterObject | filter : search">
Where "filterObject" is an object for searching an individual property and "Search" will search in every property globally.

I've spent some time on it and thanks to #chrismarx, I saw that angular's default filterFilter allows you to pass your own comparator. Here's the edited comparator for multiple values:
function hasCustomToString(obj) {
return angular.isFunction(obj.toString) && obj.toString !== Object.prototype.toString;
}
var comparator = function (actual, expected) {
if (angular.isUndefined(actual)) {
// No substring matching against `undefined`
return false;
}
if ((actual === null) || (expected === null)) {
// No substring matching against `null`; only match against `null`
return actual === expected;
}
// I edited this to check if not array
if ((angular.isObject(expected) && !angular.isArray(expected)) || (angular.isObject(actual) && !hasCustomToString(actual))) {
// Should not compare primitives against objects, unless they have custom `toString` method
return false;
}
// This is where magic happens
actual = angular.lowercase('' + actual);
if (angular.isArray(expected)) {
var match = false;
expected.forEach(function (e) {
e = angular.lowercase('' + e);
if (actual.indexOf(e) !== -1) {
match = true;
}
});
return match;
} else {
expected = angular.lowercase('' + expected);
return actual.indexOf(expected) !== -1;
}
};
And if we want to make a custom filter for DRY:
angular.module('myApp')
.filter('filterWithOr', function ($filter) {
var comparator = function (actual, expected) {
if (angular.isUndefined(actual)) {
// No substring matching against `undefined`
return false;
}
if ((actual === null) || (expected === null)) {
// No substring matching against `null`; only match against `null`
return actual === expected;
}
if ((angular.isObject(expected) && !angular.isArray(expected)) || (angular.isObject(actual) && !hasCustomToString(actual))) {
// Should not compare primitives against objects, unless they have custom `toString` method
return false;
}
console.log('ACTUAL EXPECTED')
console.log(actual)
console.log(expected)
actual = angular.lowercase('' + actual);
if (angular.isArray(expected)) {
var match = false;
expected.forEach(function (e) {
console.log('forEach')
console.log(e)
e = angular.lowercase('' + e);
if (actual.indexOf(e) !== -1) {
match = true;
}
});
return match;
} else {
expected = angular.lowercase('' + expected);
return actual.indexOf(expected) !== -1;
}
};
return function (array, expression) {
return $filter('filter')(array, expression, comparator);
};
});
And then we can use it anywhere we want:
$scope.list=[
{name:'Jack Bauer'},
{name:'Chuck Norris'},
{name:'Superman'},
{name:'Batman'},
{name:'Spiderman'},
{name:'Hulk'}
];
<ul>
<li ng-repeat="item in list | filterWithOr:{name:['Jack','Chuck']}">
{{item.name}}
</li>
</ul>
Finally here's a plunkr.
Note: Expected array should only contain simple objects like String, Number etc.
you can use searchField filter of angular.filter
JS:
$scope.users = [
{ first_name: 'Sharon', last_name: 'Melendez' },
{ first_name: 'Edmundo', last_name: 'Hepler' },
{ first_name: 'Marsha', last_name: 'Letourneau' }
];
HTML:
<input ng-model="search" placeholder="search by full name"/>
<th ng-repeat="user in users | searchField: 'first_name': 'last_name' | filter: search">
{{ user.first_name }} {{ user.last_name }}
</th>
<!-- so now you can search by full name -->
You can also use ngIf if the situation permits:
<div ng-repeat="p in [
{ name: 'Justin' },
{ name: 'Jimi' },
{ name: 'Bob' }
]" ng-if="['Jimi', 'Bob'].indexOf(e.name) > -1">
{{ p.name }} is cool
</div>
The quickest solution that I've found is to use the filterBy filter from angular-filter, for example:
<input type="text" placeholder="Search by name or genre" ng-model="ctrl.search"/>
<ul>
<li ng-repeat="movie in ctrl.movies | filterBy: ['name', 'genre']: ctrl.search">
{{movie.name}} ({{movie.genre}}) - {{movie.rating}}
</li>
</ul>
The upside is that angular-filter is a fairly popular library (~2.6k stars on GitHub) which is still actively developed and maintained, so it should be fine to add it to your project as a dependency.
I believe this is what you're looking for:
<div>{{ (collection | fitler1:args) + (collection | filter2:args) }}</div>
Please try this
var m = angular.module('yourModuleName');
m.filter('advancefilter', ['$filter', function($filter){
return function(data, text){
var textArr = text.split(' ');
angular.forEach(textArr, function(test){
if(test){
data = $filter('filter')(data, test);
}
});
return data;
}
}]);
Lets assume you have two array, one for movie and one for genre
Just use the filter as: filter:{genres: genres.type}
Here genres being the array and type has value for genre
I wrote this for strings AND functionality (I know it's not the question but I searched for it and got here), maybe it can be expanded.
String.prototype.contains = function(str) {
return this.indexOf(str) != -1;
};
String.prototype.containsAll = function(strArray) {
for (var i = 0; i < strArray.length; i++) {
if (!this.contains(strArray[i])) {
return false;
}
}
return true;
}
app.filter('filterMultiple', function() {
return function(items, filterDict) {
return items.filter(function(item) {
for (filterKey in filterDict) {
if (filterDict[filterKey] instanceof Array) {
if (!item[filterKey].containsAll(filterDict[filterKey])) {
return false;
}
} else {
if (!item[filterKey].contains(filterDict[filterKey])) {
return false;
}
}
}
return true;
});
};
});
Usage:
<li ng-repeat="x in array | filterMultiple:{key1: value1, key2:[value21, value22]}">{{x.name}}</li>
Angular Or Filter Module
$filter('orFilter')([{..}, {..} ...], {arg1, arg2, ...}, false)
here is the link: https://github.com/webyonet/angular-or-filter
I had similar situation. Writing custom filter worked for me. Hope this helps!
JS:
App.filter('searchMovies', function() {
return function (items, letter) {
var resulsts = [];
var itemMatch = new RegExp(letter, 'i');
for (var i = 0; i < items.length; i++) {
var item = items[i];
if ( itemMatch.test(item.name) || itemMatch.test(item.genre)) {
results.push(item);
}
}
return results;
};
});
HTML:
<div ng-controller="MoviesCtrl">
<ul>
<li ng-repeat="movie in movies | searchMovies:filterByGenres">
{{ movie.name }} {{ movie.genre }}
</li>
</ul>
</div>
Here is my example how create filter and directive for table jsfiddle
directive get list (datas) and create table with filters
<div ng-app="autoDrops" ng-controller="HomeController">
<div class="row">
<div class="col-md-12">
<h1>{{title}}</h1>
<ng-Multiselect array-List="datas"></ng-Multiselect>
</div>
</div>
</div>
my pleasure if i help you
Too late to join the party but may be it can help someone:
We can do it in two step, first filter by first property and then concatenate by second filter:
$scope.filterd = $filter('filter')($scope.empList, { dept: "account" });
$scope.filterd = $scope.filterd.concat($filter('filter')($scope.empList, { dept: "sales" }));
See the working fiddle with multiple property filter
OPTION 1:
Using Angular providered filter comparator parameter
// declaring a comparator method
$scope.filterBy = function(actual, expected) {
return _.contains(expected, actual); // uses underscore library contains method
};
var employees = [{name: 'a'}, {name: 'b'}, {name: 'c'}, {name: 'd'}];
// filter employees with name matching with either 'a' or 'c'
var filteredEmployees = $filter('filter')(employees, {name: ['a','c']}, $scope.filterBy);
OPTION 2:
Using Angular providered filter negation
var employees = [{name: 'a'}, {name: 'b'}, {name: 'c'}, {name: 'd'}];
// filter employees with name matching with either 'a' or 'c'
var filteredEmployees = $filter('filter')($filter('filter')(employees, {name: '!d'}), {name: '!b'});
My solution
ng-repeat="movie in movies | filter: {'Action'} + filter: {'Comedy}"
the best answer is :
filter:({genres: 'Action', genres: 'Comedy'}
I have an object that looks like this:
$scope.things = [
{
name: 'Bob!',
short_name: 'bob',
info: 'something something'
},
{
name: 'Steve',
short_name: 'steve',
info: 'something something something'
},
];
I loop through them like this and add an ng-click:
<div ng-repeat="thing in things" ng-click="addThing(thing.name, thing.short_name, thing_info" ng-class="thingClass(thing.name)">content goes here</div>
the ng-click="addThing()" basically bunches up the values and adds them to the object.
When clicked, it should add the class selected - this worked fine and dandy when I wasn't using a multidimensional object, because it was simply looking for name inside the object / array (at this point, I think it's an object... but at the time, it was an array)
I can't work out how to do the equivalent to this...
$scope.thingClass= function(name) {
if($scope.thingSelected.indexOf(name) != -1) {
return 'selected';
}
};
...with the object as it now stands. I've tried to adapt a few answers from here that I found through google, such as:
$scope.teamClass = function(name) {
var found = $filter('filter')($scope.thingSelected, {id: name}, true);
if (found.length) {
return 'selected';
}
};
...but with no joy.
Can anyone point / nudge me in the right direction?
You could simply pass the thing object to thingClass:
... ng-class="thingClass(thing)" ...
and implement thingClass as follows:
$scope.thingClass= function(thing) {
return $scope.thingSelected.indexOf(thing) >= 0 ? 'selected' : '';
}
And maybe your should apply this technique to addThing also:
... ng-click="addThing(thing)" ...
$scope.addThing = function(thing) {
if ($scope.thingSelected.indexOf(thing) < 0)
$scope.thingSelected.push(thing);
}
But instead of tracking the selected things in an array its much easier to introduce a selected property in each thing:
$scope.addThing = function(thing) {
thing.selected = true;
}
$scope.thingClass= function(thing) {
return thing.selected ? 'selected' : '';
}

The issue is that you are trying to inject production_range into your acura factory. But production_range is a variable on a controller's scope, not a factory or service that can be injected.
The second parameter to a factory should be a function that takes dependencies as its parameters. By dependencies I mean factories / services or anything else thats created from a provider, see https://docs.angularjs.org/guide/services and https://docs.angularjs.org/guide/providers.

I'm wondering if there's an easy way in Angular to filter a table using ng-repeat on specific columns using or logic, rather than and. Right now, my filter is searching everything in the table (10+ columns of data), when it really only needs to filter on 2 columns of data (ID and Name).
I've managed to get it down to look only at those 2 columns when filtering (by using an object in the filter expression as per the docs and looking at this SO answer), but it's using and logic, which is too specific. I'd like to get it to use or logic, but am having trouble.
My HTML
<input type="text" ng-model="filterText" />
<table>
<tr ng-repeat="item in data"><td>{{ item.id }}</td><td>{{ item.name }}</td>...</tr>
</table>
My filter logic:
$filter('filter')(data, {id:$scope.filterText, name:$scope.filterText})
The filtering works, but again, it's taking the intersection of the matching columns rather than the union. Thanks!
It's not hard to create a custom filter which allows you to have as many arguments as you want. Below is an example of a filter with one and two arguments, but you can add as many as you need.
Example JS:
var app = angular.module('myApp',[]);
app.filter('myTableFilter', function(){
// Just add arguments to your HTML separated by :
// And add them as parameters here, for example:
// return function(dataArray, searchTerm, argumentTwo, argumentThree) {
return function(dataArray, searchTerm) {
// If no array is given, exit.
if (!dataArray) {
return;
}
// If no search term exists, return the array unfiltered.
else if (!searchTerm) {
return dataArray;
}
// Otherwise, continue.
else {
// Convert filter text to lower case.
var term = searchTerm.toLowerCase();
// Return the array and filter it by looking for any occurrences of the search term in each items id or name.
return dataArray.filter(function(item){
var termInId = item.id.toLowerCase().indexOf(term) > -1;
var termInName = item.name.toLowerCase().indexOf(term) > -1;
return termInId || termInName;
});
}
}
});
Then in your HTML:
<tr ng-repeat="item in data | myTableFilter:filterText">
Or if you want to use multiple arguments:
<tr ng-repeat="item in data | myTableFilter:filterText:argumentTwo:argumentThree">
Use this to search on All Columns (can be slow): search.$
AngularJS API: filter
Any Column Search:
<input ng-model="search.$">
<table>
<tr ng-repeat="friendObj in friends | filter:search:strict">
...
To expand on the excellent answer by #charlietfl, here's a custom filter that filters by one column(property) which is passed to the function dynamically instead of being hard-coded. This would allow you to use the filter in different tables.
var app=angular.module('myApp',[]);
app.filter('filterByProperty', function () {
/* array is first argument, each addiitonal argument is prefixed by a ":" in filter markup*/
return function (dataArray, searchTerm, propertyName) {
if (!dataArray) return;
/* when term is cleared, return full array*/
if (!searchTerm) {
return dataArray
} else {
/* otherwise filter the array */
var term = searchTerm.toLowerCase();
return dataArray.filter(function (item) {
return item[propertyName].toLowerCase().indexOf(term) > -1;
});
}
}
});
Now on the mark-up side
<input type="text" ng-model="filterText" />
<table>
<tr ng-repeat="item in data |filterByProperty:filterText:'name'"><td>{{ item.id }}</td><td>{{ item.name }}</td>...</tr>
</table>
I figured it out- I had to write my own custom filter. Here is my solution:
var filteredData;
filteredData = $filter('filter')(data, function(data) {
if ($scope.filter) {
return data.id.toString().indexOf($scope.filter) > -1 || data.name.toString().indexOf($scope.filter) > -1;
} else {
return true;
}
});
I created this filter to perform search in several fields:
var find = function () {
return function (items,array) {
var model = array.model;
var fields = array.fields;
var clearOnEmpty = array.clearOnEmpty || false;
var filtered = [];
var inFields = function(row,query) {
var finded = false;
for ( var i in fields ) {
var field = row[fields[i]];
if ( field != undefined ) {
finded = angular.lowercase(row[fields[i]]).indexOf(query || '') !== -1;
}
if ( finded ) break;
}
return finded;
};
if ( clearOnEmpty && model == "" ) return filtered;
for (var i in items) {
var row = items[i];
var query = angular.lowercase(model);
if (query.indexOf(" ") > 0) {
var query_array = query.split(" ");
var x;
for (x in query_array) {
query = query_array[x];
var search_result = true;
if ( !inFields(row,query) ) {
search_result = false;
break;
}
}
} else {
search_result = inFields(row,query);
}
if ( search_result ) {
filtered.push(row);
}
}
return filtered;
};
};
How to use:
<tr repeat="item in colletion
| find: {
model : model, // Input model
fields : [ // Array of fields to filter
'FIELD1',
'FIELD2',
'FIELD3'
],
clearOnEmpty: true // Clear rows on empty model (not obligatory)
} "></tr>
Easily We can do this type Following written code according you will easily create another field filter....
var myApp = angular.module('myApp',[]);
myApp.filter('myfilter',myfilter);
function myfilter(){
return function (items, filters) {
if (filters == null) {
return items;
}
var filtered = [];
//Apply filter
angular.forEach(items, function (item) {
if ((filters.Name == '' || angular.lowercase(item.Name).indexOf(angular.lowercase(filters.Name)) >= 0)
)
{
filtered.push(item);
}
});
return filtered;
};
}
myApp.controller('mycontroller',['$scope',function($scope){
$scope.filters={Name:'',MathsMarks:''};
$scope.students=[];
var i=0;
for(i=0;i<5;i++){
var item={Name:'',Marks:[]};
item.Name='student' + i;
item.Marks.push({Maths:50-i,Science:50 +i});
$scope.students.push(item);
}
}]);
<html ng-app='myApp'>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.21/angular.min.js"></script>
</head>
<body ng-controller='mycontroller'>
<input type='text' name='studentName' ng-model="filters.Name" placeholder='Enter Student Name'>
<div ng-repeat="student in students | myfilter: filters">
Name : {{student.Name}} Marks == >
<span ng-repeat="m in student.Marks">Maths:{{m.Maths}} Science:{{m.Science}}</span>
</div>
</body>
</html>
Here is my solution, it's very lazy, it will search on all strings in array on first level, you could update this to recusively go down the tree, but this should be good enough...
app.filter('filterAll', function () {
return function (dataArray, searchTerm, propertyNames) {
if (!dataArray) return;
if (!searchTerm) {
return dataArray;
} else {
if (propertyNames == undefined) {
propertyNames = [];
for (var property in dataArray[0]) {
if(typeof dataArray[0][property] == "string" &&
property != "$$hashKey" &&
property != "UnitName" )
propertyNames.push(property);
}
}
console.log("propertyNames", propertyNames);
var term = searchTerm.toLowerCase();
return dataArray.filter(function (item) {
var found = false;
propertyNames.forEach(function(val) {
if (!found) {
if (item[val] != null && item[val].toLowerCase().indexOf(term) > -1)
found = true;
}
});
return found;
});
}
}
});
