I'm new to Angularjs, i want to display the entire month dates as a header, when im selected from the date picker for that particular month dates should be display like that only for other month based on the selection, to check the attendance of the employee
You should try this:
create month HTML which will be:
<select ng-model="calculate.months" ng-change="monthCalculate(calculate.months)">
<option ng-repeat="x in monthsValue" value="{{x.value}}">{{x.name}}</option>
</select>
in app.js
$scope.monthsValue = [
{name: "January", value: "1"},
{name: "February", value: "2"},
{name: "march", value: "3"}
];
for dynamic month bind.
lets print month days in angularjs:
Selected Month : {{ calculate.months}}
<div ng-model="totalDays">
<div ng-repeat="i in range(totalDays) track by $index">
<span> {{$index + 1}} </span>
</div>
</div>
and in app.js :
$scope.monthCalculate = function (months) {
getMonthDays = daysInMonth(months, 2016);
$scope.totalDays = getMonthDays;
};
function daysInMonth(month, year) {
return new Date(year, month, 0).getDate();
}
$scope.range = function (n) {
return new Array(n);
};
Lets give it a try Hope this helps you.

How sort string date format 24.01.2017 ( descending )
I tried with Date.parse('24.01.2017'); -> but incorrect format
How sort date like this?
in controller or view
Thanks
Getting data from api
want sort by _title
Try the orderBy filter with a custom comparing function:
JS:
$scope.entries = [
{date: '05.02.2001'},
{date: '01.20.1930'},
{date: '03.20.2020'}
]
$scope.compareDates = function(date1, date2) {
console.log(date1)
var split1 = date1.value.split('.');
var split2 = date2.value.split('.');
var date1compare = split1[2] + split1[1] + split1[0];
var date2compare = split2[2] + split2[1] + split2[0];
return (date1compare > date2compare ? 1 : -1)
}
HTML:
<div ng-repeat="entry in entries | orderBy:'date':false:compareDates">
{{entry.date}}
</div>

The data I am receiving from a webservice is formatted as dd/mm/yyyy. The problem with this is when sorting, it sorts by dd rather than yyyy.
<td ng-repeat="thead in resultHeader">
{{thead.head}}
<span class="sortorder" ng-show="predicate === thead.line" ng-class="{reverse:reverse}"></span>
</td>
Controller:
$scope.order = function(predicate) {
var results = $scope.model.resultList;
$scope.reverse = ($scope.predicate === predicate) ? !$scope.reverse : false;
$scope.predicate = predicate;
$scope.model.currentPage = 1;
$scope.model.beginFrom = 0;
};
How can I sort this data by yyyy with my current set up?
{
"name": "Test",
"ShipmentDate": "06\/08\/2012"
}
The key part is to add a $filter to your module and use that $filter to get the Date value from the string. you can use Date.parse('dd/mm/yyyy') to get the time in float, and then run an Array.sort() to your data.
If you converted your date strings to Date objects, you can use the orderBy: filter to sort by date.
<td ng-repeat="thead in resultHeader | orderBy:'ShipmentDate':shouldBeReversedOrder ">
{{thead.head}}
<span class="sortorder" ng-show="predicate === thead.line" ng-class="{reverse:reverse}"></span>
</td>
When you want to display the date back in a proper formate you can use {{thead.ShipmentDate | 'yyyy-mm-dd'}} to format it for you.
Use the custom order for this. Look:
function MyCtrl($scope, orderByFilter) {
$scope.sortedFriends = [
{
name: 'John',
age: 25,
dateTest: '10/10/2015'
}, {
name: 'Jimmy',
age: 25,
dateTest: '10/12/2015'
},{
name: 'Mary',
age: 28,
dateTest: '10/09/2009'
}, {
name: 'Ed',
age: 27,
dateTest: '30/03/2014'
},{
name: 'Andrew',
age: 27,
dateTest: '11/11/2016'
}];
$scope.orderByCustom = function(friend) {
console.log(friend)
return friend.dateTest.split('/')[2];
};
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app ng-controller="MyCtrl">
<ul>
<li ng-repeat="friend in sortedFriends | orderBy:orderByCustom"">
{{friend}}
</li>
</ul>
</div>
My goal is to apply a formatting filter that is set as a property of the looped object.
Taking this array of objects:
[
{
"value": "test value with null formatter",
"formatter": null,
},
{
"value": "uppercase text",
"formatter": "uppercase",
},
{
"value": "2014-01-01",
"formatter": "date",
}
]
The template code i'm trying to write is this:
<div ng-repeat="row in list">
{{ row.value | row.formatter }}
</div>
And i'm expecting to see this result:
test value with null formatter
UPPERCASE TEXT
Jan 1, 2014
But maybe obviusly this code throws an error:
Unknown provider: row.formatterFilterProvider <- row.formatterFilter
I can't immagine how to parse the "formatter" parameter inside the {{ }}; can anyone help me?
See the plunkr http://plnkr.co/edit/YnCR123dRQRqm3owQLcs?p=preview
The | is an angular construct that finds a defined filter with that name and applies it to the value on the left. What I think you need to do is create a filter that takes a filter name as an argument, then calls the appropriate filter (fiddle) (adapted from M59's code):
HTML:
<div ng-repeat="row in list">
{{ row.value | picker:row.formatter }}
</div>
Javascript:
app.filter('picker', function($filter) {
return function(value, filterName) {
return $filter(filterName)(value);
};
});
Thanks to #karlgold's comment, here's a version that supports arguments. The first example uses the add filter directly to add numbers to an existing number and the second uses the useFilter filter to select the add filter by string and pass arguments to it (fiddle):
HTML:
<p>2 + 3 + 5 = {{ 2 | add:3:5 }}</p>
<p>7 + 9 + 11 = {{ 7 | useFilter:'add':9:11 }}</p>
Javascript:
app.filter('useFilter', function($filter) {
return function() {
var filterName = [].splice.call(arguments, 1, 1)[0];
return $filter(filterName).apply(null, arguments);
};
});
I like the concept behind these answers, but don't think they provide the most flexible possible solution.
What I really wanted to do and I'm sure some readers will feel the same, is to be able to dynamically pass a filter expression, which would then evaluate and return the appropriate result.
So a single custom filter would be able to process all of the following:
{{ammount | picker:'currency:"$":0'}}
{{date | picker:'date:"yyyy-MM-dd HH:mm:ss Z"'}}
{{name | picker:'salutation:"Hello"'}} //Apply another custom filter
I came up with the following piece of code, which utilizes the $interpolate service into my custom filter. See the jsfiddle:
Javascript
myApp.filter('picker', function($interpolate ){
return function(item,name){
var result = $interpolate('{{value | ' + arguments[1] + '}}');
return result({value:arguments[0]});
};
});
One way to make it work is to use a function for the binding and do the filtering within that function. This may not be the best approach: Live demo (click).
<div ng-repeat="row in list">
{{ foo(row.value, row.filter) }}
</div>
JavaScript:
$scope.list = [
{"value": "uppercase text", "filter": "uppercase"}
];
$scope.foo = function(value, filter) {
return $filter(filter)(value);
};
I had a slightly different need and so modified the above answer a bit (the $interpolate solution hits the same goal but is still limited):
angular.module("myApp").filter("meta", function($filter)
{
return function()
{
var filterName = [].splice.call(arguments, 1, 1)[0] || "filter";
var filter = filterName.split(":");
if (filter.length > 1)
{
filterName = filter[0];
for (var i = 1, k = filter.length; i < k; i++)
{
[].push.call(arguments, filter[i]);
}
}
return $filter(filterName).apply(null, arguments);
};
});
Usage:
<td ng-repeat="column in columns">{{ column.fakeData | meta:column.filter }}</td>
Data:
{
label:"Column head",
description:"The label used for a column",
filter:"percentage:2:true",
fakeData:-4.769796600014472
}
(percentage is a custom filter that builds off number)

Here is how I used it.
$scope.table.columns = [{ name: "June 1 2015", filter: "date" },
{ name: "Name", filter: null },
] etc...
<td class="table-row" ng-repeat="column in table.columns">
{{ column.name | applyFilter:column.filter }}
</td>
app.filter('applyFilter', [ '$filter', function( $filter ) {
return function ( value, filterName ) {
if( !filterName ){ return value; } // In case no filter, as in NULL.
return $filter( filterName )( value );
};
}]);
I improved #Jason Goemaat's answer a bit by adding a check if the filter exists, and if not return the first argument by default:
.filter('useFilter', function ($filter, $injector) {
return function () {
var filterName = [].splice.call(arguments, 1, 1)[0];
return $injector.has(filterName + 'Filter') ? $filter(filterName).apply(null, arguments) : arguments[0];
};
});
The newer version of ng-table allows for dynamic table creation (ng-dynamic-table) based on a column configuration. Formatting a date field is as easy as adding the format to your field value in your columns array.
Given
{
"name": "Test code",
"dateInfo": {
"createDate": 1453480399313
"updateDate": 1453480399313
}
}
columns = [
{field: 'object.name', title: 'Name', sortable: 'name', filter: {name: 'text'}, show: true},
{field: "object.dateInfo.createDate | date :'MMM dd yyyy - HH:mm:ss a'", title: 'Create Date', sortable: 'object.dateInfo.createDate', show: true}
]
<table ng-table-dynamic="controller.ngTableObject with controller.columns" show-filter="true" class="table table-condensed table-bordered table-striped">
<tr ng-repeat="row in $data">
<td ng-repeat="column in $columns">{{ $eval(column.field, { object: row }) }}</td>
</tr>
</table>
I ended up doing something a bit more crude, but less involving:
HTML:
Use the ternary operator to check if there is a filter defined for the row:
ng-bind="::data {{row.filter ? '|' + row.filter : ''}}"
JS:
In the data array in Javascript add the filter:
, {
data: 10,
rowName: "Price",
months: [],
tooltip: "Price in DKK",
filter: "currency:undefined:0"
}, {
This is what I use (Angular Version 1.3.0-beta.8 accidental-haiku).
This filter allows you to use filters with or without filter options.
applyFilter will check if the filter exists in Angular, if the filter does not exist, then an error message with the filter name will be in the browser console like so...
The following filter does not exist: greenBananas
When using ng-repeat, some of the values will be undefined. applyFilter will handle these issues with a soft fail.
app.filter( 'applyFilter', ['$filter', '$injector', function($filter, $injector){
var filterError = "The following filter does not exist: ";
return function(value, filterName, options){
if(noFilterProvided(filterName)){ return value; }
if(filterDoesNotExistInAngular(filterName)){ console.error(filterError + "\"" + filterName + "\""); return value; }
return $filter(filterName)(value, applyOptions(options));
};
function noFilterProvided(filterName){
return !filterName || typeof filterName !== "string" || !filterName.trim();
}
function filterDoesNotExistInAngular(filterName){
return !$injector.has(filterName + "Filter");
}
function applyOptions(options){
if(!options){ return undefined; }
return options;
}
}]);
Then you use what ever filter you want, which may or may not have options.
// Where, item => { name: "Jello", filter: {name: "capitalize", options: null }};
<div ng-repeat="item in items">
{{ item.name | applyFilter:item.filter.name:item.filter.options }}
</div>
Or you could use with separate data structures when building a table.
// Where row => { color: "blue" };
// column => { name: "color", filter: { name: "capitalize", options: "whatever filter accepts"}};
<tr ng-repeat="row in rows">
<td ng-repeat="column in columns">
{{ row[column.name] | applyFilter:column.filter.name:column.filter.options }}
</td>
</tr>
If you find that you require to pass in more specific values you can add more arguments like this...
// In applyFilter, replace this line
return function(value, filterName, options){
// with this line
return function(value, filterName, options, newData){
// and also replace this line
return $filter(filterName)(value, applyOptions(options));
// with this line
return $filter(filterName)(value, applyOptions(options), newData);
Then in your HTML perhaps your filter also requires a key from the row object
// Where row => { color: "blue", addThisToo: "My Favorite Color" };
// column => { name: "color", filter: { name: "capitalize", options: "whatever filter accepts"}};
<tr ng-repeat="row in rows">
<td ng-repeat="column in columns">
{{ row[column.name] | applyFilter:column.filter.name:column.filter.options:row.addThisToo }}
</td>
</tr>
I want to make some kind of project list from a JSON file. The data structure (year, month, project) looks like this:
[{
"name": "2013",
"months": [{
"name": "May 2013",
"projects": [{
"name": "2013-05-09 Project A"
}, {
"name": "2013-05-14 Project B"
}, { ... }]
}, { ... }]
}, { ... }]
I'm displaying all data using a nested ng-repeat and make it searchable by a filter bound to the query from an input box.
<input type="search" ng-model="query" placeholder="Suchen..." />
<div class="year" ng-repeat="year in data | orderBy:'name':true">
<h1>{{year.name}}</h1>
<div class="month" ng-repeat="month in year.months | orderBy:sortMonth:true">
<h3>{{month.name}}</h3>
<div class="project" ng-repeat="project in month.projects | filter:query | orderBy:'name'">
<p>{{project.name}}</p>
</div>
</div>
</div>
If I type "Project B" now, all the empty parent elements are still visible. How can I hide them? I tried some ng-show tricks, but the main problem seems so be, that I don't have access to any information about the parents filtered state.
Here is a fiddle to demonstrate my problem: http://jsfiddle.net/stekhn/y3ft0cwn/7/
You basically have to filter the months to only keep the ones having at least one filtered project, and you also have to filter the years to only keep those having at least one filtered month.
This can be easily achieved using the following code:
function MainCtrl($scope, $filter) {
$scope.query = '';
$scope.monthHasVisibleProject = function(month) {
return $filter('filter')(month.children, $scope.query).length > 0;
};
$scope.yearHasVisibleMonth = function(year) {
return $filter('filter')(year.children, $scope.monthHasVisibleProject).length > 0;
};
and in the view:
<div class="year" ng-repeat="year in data | filter:yearHasVisibleMonth | orderBy:'name':true">
<h1>{{year.name}}</h1>
<div class="month" ng-repeat="month in year.children | filter:monthHasVisibleProject | orderBy:sortMonth:true">
This is quite inefficient though, since to know if a year is accepted, you filter all its months, and for each month, you filter all its projects. So, unless the performance is good enough for your amount of data, you should probably apply the same principle but by persisting the accepted/rejected state of each object (project, then month, then year) every time the query is modified.
I think that the best way to go is to implement a custom function in order to update a custom Array with the filtered data whenever the query changes. Like this:
$scope.query = '';
$scope.filteredData= angular.copy($scope.data);
$scope.updateFilteredData = function(newVal){
var filtered = angular.copy($scope.data);
filtered = filtered.map(function(year){
year.children=year.children.map(function(month){
month.children = $filter('filter')(month.children,newVal);
return month;
});
return year;
});
$scope.filteredData = filtered.filter(function(year){
year.children= year.children.filter(function(month){
return month.children.length>0;
});
return year.children.length>0;
});
}
And then your view will look like this:
<input type="search" ng-model="query" ng-change="updateFilteredData(query)"
placeholder="Search..." />
<div class="year" ng-repeat="year in filteredData | orderBy:'name':true">
<h1>{{year.name}}</h1>
<div class="month" ng-repeat="month in year.children | orderBy:sortMonth:true">
<h3>{{month.name}}</h3>
<div class="project" ng-repeat="project in month.children | orderBy:'name'">
<p>{{project.name}}</p>
</div>
</div>
</div>
Example
Why not a custom $filter for this?
Efficiency: the nature of the $diggest cycle would make it much less efficient. The only problem is that this solution won't be as easy to re-use as a custom $filter would. However, that custom $filter wouldn't be very reusable either, since its logic would be very dependent on this concrete data structure.
IE8 Support
If you need this to work on IE8 you will have to either use jQuery to replace the filter and map functions or to ensure that those functions are defined, like this:
(BTW: if you need IE8 support there is absolutely nothing wrong with using jQuery for these kind of things.)
filter:
if (!Array.prototype.filter) {
Array.prototype.filter = function(fun/*, thisArg*/) {
'use strict';
if (this === void 0 || this === null) {
throw new TypeError();
}
var t = Object(this);
var len = t.length >>> 0;
if (typeof fun !== 'function') {
throw new TypeError();
}
var res = [];
var thisArg = arguments.length >= 2 ? arguments[1] : void 0;
for (var i = 0; i < len; i++) {
if (i in t) {
var val = t[i];
if (fun.call(thisArg, val, i, t)) {
res.push(val);
}
}
}
return res;
};
}
map
if (!Array.prototype.map) {
Array.prototype.map = function(callback, thisArg) {
var T, A, k;
if (this == null) {
throw new TypeError(" this is null or not defined");
}
var O = Object(this);
var len = O.length >>> 0;
if (typeof callback !== "function") {
throw new TypeError(callback + " is not a function");
}
if (thisArg) {
T = thisArg;
}
A = new Array(len);
k = 0;
while(k < len) {
var kValue, mappedValue;
if (k in O) {
kValue = O[ k ];
mappedValue = callback.call(T, kValue, k, O);
A[ k ] = mappedValue;
}
k++;
}
return A;
};
}
Acknowledgement
I want to thank JB Nizet for his feedback.
For those who are interested: Yesterday I found another approach for solving this problem, which strikes me as rather inefficient. The functions gets called for every child again while typing the query. Not nearly as nice as Josep's solution.
function MainCtrl($scope) {
$scope.query = '';
$scope.searchString = function () {
return function (item) {
var string = JSON.stringify(item).toLowerCase();
var words = $scope.query.toLowerCase();
if (words) {
var filterBy = words.split(/\s+/);
if (!filterBy.length) {
return true;
}
} else {
return true;
}
return filterBy.every(function (word) {
var exists = string.indexOf(word);
if(exists !== -1){
return true;
}
});
};
};
};
And in the view:
<div class="year" ng-repeat="year in data | filter:searchString() | orderBy:'name':true">
<h1>{{year.name}}</h1>
<div class="month" ng-repeat="month in year.children | filter:searchString() | orderBy:sortMonth:true">
<h3>{{month.name}}</h3>
<div class="project" ng-repeat="project in month.children | filter:searchString() | orderBy:'name'">
<p>{{project.name}}</p>
</div>
</div>
</div>
Here is the fiddle: http://jsfiddle.net/stekhn/stv55sxg/1/
Doesn't this work? Using a filtered variable and checking the length of it..
<input type="search" ng-model="query" placeholder="Suchen..." />
<div class="year" ng-repeat="year in data | orderBy:'name':true" ng-show="filtered.length != 0">
<h1>{{year.name}}</h1>
<div class="month" ng-repeat="month in year.months | orderBy:sortMonth:true">
<h3>{{month.name}}</h3>
<div class="project" ng-repeat="project in filtered = (month.projects | filter:query) | orderBy:'name'">
<p>{{project.name}}</p>
</div>
</div>
