Thanks
You want to avoid displaying the table something when searchText.category is undefined or empty:
<table ng-show="searchText.category && searchText.category.length != 0">
or
<table ng-if="searchText.category && searchText.category.length != 0">

I have an ng-repeat that iterates over a document where I want to do a " | filter:search", but want the filter to run on specific fields in the document.
I found a couple examples, that just don't work.
(I have an input field with a model=search)...
The way they say you target specific fields is like this:
<div ng-repeat="x in data | filter({first_name:search,last_name:search })">{{x.first_name}} {{x.last_name}}</div>
I remember doing something in the past and I think this is close, but not quite.
Any help?
<div ng-repeat="obj in objs | filter:filterFn">{{obj.name}}</div>
see this is the function : filterFn
$scope.filterFn = function(elm)
{
if($scope.filterlocation[elm.location])
{
return true;
}
return false;
};
// Code goes here
(function(){
var myApp = angular.module('myApp',['angular.filter']);
myApp.controller('myCtrl', function($scope){
var vm= this;
vm.x = 20;
vm.tableData = [
{
first_name: 'Programmer',
last_name: '21',
},{
first_name: 'Abc',
last_name: 'Xyz'
},{
first_name: 'Kunvar',
last_name: 'Singh'
},{
first_name: 'Cnak',
last_name: '2'
}
];
})

will be searched. all columns will be used by default if you use <b>filter: vm.searchText</b></p>

This is an example for a table to search for eachColumn and for all colums in an input all.
Heres the example ->pnlkr
All can be done in the view.

but i am not getting the data when i tried to use bullet chart, other wise i am getting data. when i am using http call for data rather than json object, following error is coming.click here for error page
Here is a simplified version of what I think you were trying to achieve. I don't quite get the .finally() function in your code, so what I do instead is map $scope.jsondata to $scope.transactionData, creating a chartData property within each item, so that when you ng-repeat over them, you can feed each of the nvd3 bullet charts its own data object.
I believe the errors you were getting were caused by the fact that you were trying to feed string values of actualVolume and expectedVolume to nvd3, so I fixed that by converting them to Number values instead:
chartData: {
ranges: [100, 150, Number(record.expectedVolume)*1.5],
measures: [Number(record.actualVolume)],
markers: [Number(record.expectedVolume)]
}
See the rest below... Hope this helps you.
var app = angular.module('plunker', ['nvd3']);
app.controller('MainCtrl', ['$scope', function ($scope) {
$scope.jsondata = [
{
'transactionName': '1',
'actualVolume':'150',
'expectedVolume':'300'
},
{
'transactionName': '2',
'actualVolume':'250',
'expectedVolume':'300'
}
];
$scope.transactionData = $scope.jsondata.map(function(record) {
return {
transactionName: record.transactionName,
actualVolume: record.actualVolume,
expectedVolume : record.expectedVolume,
chartData: {
ranges: [100, 150, Number(record.expectedVolume)*1.5],
measures: [Number(record.actualVolume)],
markers: [Number(record.expectedVolume)]
}
};
});
$scope.options1 = {
chart: {
type: 'bulletChart',
transitionDuration: 500
}
};
}]);

I want to filter the ng-repeat values using
ng-repeat="obj in object | filter :searchtext"
but it should show the result only after the user give values to the searchtext.
it shouldn't list out the values on page load itself.
Thanks in advance :)
you can use ng-show=searchtext on ng-repeat element.
try this snippet
function ListCrtl($scope) {
$scope.items = [1, 2, 3, 4, 5];
}
<!DOCTYPE html>
<html ng-app>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.1.5/angular.min.js"></script>
</head>
<body>
<div ng-controller="ListCrtl">
<input ng-model="search.term" />
<p ng-show="search.term" ng-repeat="item in items|filter:search.term">{{item}}</p>
</div>
</body>
</html>
Have condition like this
ng-if="searchtext" ng-repeat="obj in object | filter :searchtext"
Example:
<!doctype html>
<html ng-app="docsSimpleDirective">
<head>
<script type="text/javascript" src="http://code.angularjs.org/1.2.13/angular.min.js"></script>
<script type="text/javascript" src="script.js"></script>
</head>
<body>
<div ng-controller="Ctrl">
<input type="search" class="form-control" placeholder="Rechercher" data-ng-model="search" />
<div ng-if="search" ng-repeat="departement in depatements | filter:search">
<pre>{{departement}}</pre>
</div>
</div>
</body>
</html>
script.js:
angular.module('docsSimpleDirective', [])
.controller('Ctrl', function($scope) {
$scope.depatements = [
{"codeDept": "01", "libelleDept": "D1", "libelleRegion":"R1", "codeRegion": "04"},

];

I have been trying to display the json data in the ng-grid since 3 hrs but could not do it.I have followed as per the instructions given in the Getting started guide of ng -grid.But could not display the data in the grid.
In my UserEdit.aspx page my HTML code is as follows:

In my Control.js file for the module i have injected the dependency of ngGrid and in my controller MyCtrl I initialize gridoptions variable.My js code is as follows
In my Control.js it is as follows:
var app = angular.module("myApp", ["ngGrid"]);
app.controller('MyCtrl', function ($scope) {
$scope.myData = [{ name: "Moroni", age: 50 },
{ name: "Tiancum", age: 43 },
{ name: "Jacob", age: 27 },
{ name: "Nephi", age: 29 },
{ name: "Enos", age: 34}];
$scope.gridOptions = {
data:'myData'
};
$scope.$apply();
});
FYI ,There are no errors that appear in console.And when i view the example given in http://angular-ui.github.io/ui-grid/ , and if i view the code in the plunker the same thing happens(i.e I cannot see any grid ).
Appreciate any Help!!
You are using MyCtrl outside of ng-app
It should be inside of it's module.
try like this
<div ng-app="myApp">
<div ng-controller="MyCtrl">
</div>
</div>
N:B : you don't need $scope.$apply(); .
In my angularjs application have an array of objects as shown below :
$scope.rowData = [{
"expNum": "678",
"itemHr": "10",
"highRe": "C"
}, {
"expNum": "978",
"itemHr": "3",
"highRe": "Y"
}]
Now on a click event I need to update 'itemHr' of each object in the array to some new value let say (25). I don't want to create new Array of object rather modify the existing only. If we can use angularjs utilities to do it or underscore library, both are fine for me. can any one help me with that.
Why not vanila js with for loop?
for(var i = 0; i<$scope.rowData.length; i++)
{
$scope.rowData[i].itemHr = 25;
}
or underscore
_.each($scope.rowData, function(item){ item.itemHr = 25;});
or angular
angular.forEach($scope.rowData,function(item){ item.itemHr = 25; });
var app = angular.module("myApp", ['ui.bootstrap']);
app.controller("maincontroller", function($scope) {
$scope.rowData = [{
"expNum": "678",
"itemHr": "10",
"highRe": "C"
}, {
"expNum": "978",
"itemHr": "3",
"highRe": "Y"
}];
$scope.update = function(){
for(var i = 0; i<$scope.rowData.length; i++)
{
$scope.rowData[i].itemHr = 25;
}
}
});
