I want to change a radio button's property on a click on a <div>.
In the below code, the div has a class and I have to change the radio button's property to true if the div is clicked.
I wrote this event handling using jQuery.
Can you tell me how to solve this using Angularjs?
var app = angular.module('myapp', []);
app.controller('MainCtrl', function($scope) {
//How to write code here in Angular//
});

Update the model value using ng-click directive
Try this:
var app = angular.module('myapp', []);
app.controller('MainCtrl', function($scope) {
$scope.val = ''
$scope.clickHadler = function(val) {
$scope.val = val;
};
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body ng-app='myapp' ng-controller="MainCtrl">
<div>
<input ng-click="Large()" ng-model='val' value='first' id="large" type="radio" name="button">Large
<input ng-click="Medium()" ng-model='val' value='second' id="medium" type="radio" name="button">medium
<input ng-click="Small()" ng-model='val' value='third' id="small" type="radio" name="button">Small
</div>
<div>
<div class="col-xs-12" ng-click='clickHadler("first")'>first //click</div>
<br/>
<div class="col-xs-6" ng-click='clickHadler("second")'>second //click</div>
<br/>
<div class="col-xs-4" ng-click='clickHadler("third")'>third //click</div>
</div>
</body>
Since you can't use label, the angular solution will be is to use model values
var app = angular.module('myapp', [], function() {})
app.controller('MainCtrl', function($scope) {
$scope.fieldClicked = function(size) {
if (size == 'col-xs-12') {
$scope.size = 'large';
} else if (size == 'col-xs-6') {
$scope.size = 'medium';
} else if (size == 'col-xs-4') {
$scope.size = 'small';
}
}
})

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myapp">
<div ng-controller="MainCtrl">
<div>
<input ng-model="size" value="large" type="radio" name="button">Large
<input ng-model="size" value="medium" type="radio" name="button">medium
<input ng-model="size" value="small" type="radio" name="button">Small
</div>
<div>
<!--ng-click="fieldClicked(div.size)" in template-->
<div class="col-xs-12 field" ng-click="fieldClicked('col-xs-12')">first</div>
<br/>
<div class="col-xs-6 field" ng-click="fieldClicked('col-xs-6')">second</div>
<br/>
<div class="col-xs-4 field" ng-click="fieldClicked('col-xs-4')">third</div>
</div>
</div>
</div>
No need of script here, just use label instead of div
var app = angular.module('myapp', [], function() {})
app.controller('MainCtrl', function($scope) {
})
<link href="http://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.3.5/css/bootstrap.css" rel="stylesheet"/>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myapp">
<div ng-controller="MainCtrl">
<div>
<input ng-click="Large()" id="large" type="radio" name="button">Large
<input ng-click="Medium()" id="medium" type="radio" name="button">medium
<input ng-click="Small()" id="small" type="radio" name="button">Small
</div>
<div>
<label for="large" class="col-xs-12 field">first</label>
<br/>
<label for="medium" class="col-xs-6 field">second</label>
<br/>
<label for="small" class="col-xs-4 field">third</label>
</div>

I am new to angularjs. I am trying a simple program which have check boxes and a disabled button. The button should be enabled after one or multiple checkboxes are selected. However, my solution seems to be not working. Any help in this respect will be great.
HTML code:
<html ng-app="Apps" ng-controller = "chk">
<head>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.6/angular.min.js"></script>
<script type="text/javascript" src="Apps.js"></script>
</head>
<body>
<center>
<h1> Fruits </h1>
<hr/>
<div >
<label ng-repeat="lbl in lbls">
<input type="checkbox" ng-model="chkd" > {{lbl}}
</label>
<br>
<input type="button" value="Submit" ng-disabled="!chkd"/>
</div>
</center>
</body>
</html>
here is the JS is file:
var Apps = angular.module ('Apps', [])
Apps.controller("chk", function($scope){
$scope.lbls = [
'Apples',
'Bananas',
'Apricots',
'Peaches'
];
});
It looks like you have to have separate conditions for each of the checkboxes for ng-disabled to detect a change. Use this HTML layout instead:
<html>
<head>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.6/angular.min.js">
</script>
</head>
<body>
<center>
<h1> Fruits </h1>
<hr/>
<div ng-app>
<input type="checkbox" ng-model="cb01"> Apples
<input type="checkbox" ng-model="cb02"> Bananas
<input type="checkbox" ng-model="cb03"> Apricots
<input type="checkbox" ng-model="cb04"> Peaches
<br>
<input type="button" value="Submit" ng-disabled="!(cb01||cb02||cb03||cb04)">
</div>
</center>
</body>
</html>
jsfiddle
EDIT
Code should now be working fine. Sorry for the confusion!
Here is an approach which you can insert other fruits, and don't need to change code in your ng-disabled:
var Apps = angular.module ('Apps', [])
Apps.controller("chk", function($scope){
$scope.chkd = {
Apples: false,
Bananas: false,
Apricots: false,
Peaches: false
};
$scope.enableSubmit = function(){
var atLeastOneSelected = [];
for (var fruit in $scope.chkd) {
if($scope.chkd[fruit] === true){
atLeastOneSelected.push(fruit);
}
}
return !(atLeastOneSelected.length > 0);
}
});
<html ng-app="Apps" ng-controller = "chk">
<head>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.6/angular.min.js"></script>
<script type="text/javascript" src="Apps.js"></script>
</head>
<body>
<center>
<h1> Fruits </h1>
<hr/>
<div >
<label ng-repeat="(lbl, enabled) in chkd">
<input type="checkbox" ng-model="chkd[lbl]"> {{lbl}}
</label>
<br>
<input type="button" value="Submit" ng-disabled="enableSubmit()"/>
</div>
</center>
</body>
</html>

So many mistakes. This is just sample. You should use $route (ng-view or ui-view) for route navigation.. I was updated plnkr.
http://embed.plnkr.co/C1ubxufRQHN4rfGooxeF/
I am trying to use Route in my newEvent page. But it's giving me 404 error. I checked my code but I am not able to identify the error.
can anyone please check my codes and let me know whats wrong im doing here. I uploaded app.js , EditEventController.js , index.html and NewEvent.html file. I also uploaded a screenshot. Please take a look and let me solve this error.
Thank you

In your html, should this entry:

... be changed to this, so that it matches the location to the other angular files?

Suppose some widget like range slider binds to a 2-element array. Also I want to display range limits in separate text fields. How to accomplish that?

I need to update array on each limit change and reverse. How to accomplish that?
You can directly bind with array elements
From: <input type="text" ng-model="vm.slider[0]" />
To: <input type="text" ng-model="vm.slider[1]" />
angular
.module('myApp', ['ui.slider']);
angular.module('myApp')
.controller('MyController', MyController);
function MyController() {
var vm = this;
vm.slider = [5, 15];
}

I am trying to create a search on AngularJs based on the snippet I found on codepen and this is the URL http://codepen.io/netsi1964/pen/AmGcg
This is a snippet on what I have tried
<div ng-app="myApp" ng-controller="Example">
<div class="container controls">
<div class="row">
<div class="col-md-12">
<form action="" method="POST" role="form">
<legend>Find a movie from YouBio</legend>
<div class="input-group">
<input type="search" id="search" class="form-control" ng-model="search">
<div class="input-group-addon">Found {{(movies | filter:search).length}} of {{movies.length}}</div>
<div class="input-group-addon "><input type="checkbox" ng-model="reverse" value="true" id="reverse" /><label for="reverse">Reverse</label></div>
<div class="input-group-addon "><input type="checkbox" ng-model="list" value="true" id="reverse" /><label for="list">List</label></div>
</div>
</form>
</div>

</div>
This is JS file:
angular.module("myApp",["ngSanitize"])
.filter('replace', function () {
var pat = / /gi;
return function (text) {
var clean = text.replace(pat, "-");
var temp = clean.split("---");
if (temp.length>1) {
clean = temp[0];
}
return clean;
};
})
.controller("Example", function($scope, $interval) {
$scope.search = "orig";
$scope.movies = youMovie;
$scope.reverse = false;
$scope.list = false;
});
And I am getting the following the error

And here is a plunk I have made

Controller, also you did't have and data to present in the view so I added some dummy data:
angular.module("myApp",["ngSanitize"])
.filter('replace', function () {
var pat = / /gi;
return function (text) {
var clean = text.replace(pat, "-");
var temp = clean.split("---");
if (temp.length>1) {
clean = temp[0];
}
return clean;
};
})
.controller('Example', ['$scope',
function($scope) {
$scope.$watch('search', function(newVal, oldVal) {
$scope.search = newVal;
$scope.movies = [{title: 'Movie 1'}, {title: 'Movie 2'}, {title: 'Movie 3'}, {title: 'Moive 4'}, {title: 'Movie 5'}];
$scope.reverse = false;
$scope.list = false;
});
}
]);
//document.querySelector('#search').focus();
You are injecting a module you have not loaded on the page. The ngSantize module is standalone from the angular.min.js source. You need to load angular-sanitize.min.js on the page.
you not load santize file like:
