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?
angular
.module('myApp', ['ui.slider']);
angular.module('myApp')
.controller('MyController', MyController);
function MyController() {
var vm = this;
vm.slider = [5,15];
}

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];
}

<strong>It's value is bound as an array:</strong>
<br>

<br>
<strong>How to bind sepately:</strong>

In your html, should this entry:
<script src="angular/angular-route.js"></script>
... be changed to this, so that it matches the location to the other angular files?
<script src="lib/angular/angular-route.js"></script>
This is a problem that can be easily done by declaring a scope function but I was wondering if there is a better way to make this easier
The code is:
<!DOCTYPE html>
<html ng-app="myApp">
<head>
<link rel="stylesheet" type="text/css" href="http://netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css">
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.9/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.2.2/jquery.min.js"></script>
</head>
<body ng-controller="myCtrl">
<input type="checkbox" ng-model="activate" id="activate"> ACTIVATE <br />
<input type="text" ng-model="first" ng-disabled="!activate">
<input type="text" ng-model="second" ng-disabled="!activate">
<!-- <span id="clickMe">Click Me!</span> -->
<script type="text/javascript">
app = angular.module('myApp', []);
app.controller('myCtrl', function($scope, $timeout){
});
</script>
</body>
</html>
So this is the case. The other two fields will be enabled if the checkbox is checked and true and will be disabled if the checkbox is unchecked. What I want is, to make the fields go null or blank automatically upon disabling.
Here is an example: http://plnkr.co/edit/2EPuhRiR9OncV8z7q018?p=preview
Ignoring the fact that it is not a good practice to put too much logic directly in the view, a technical solution would be:
<input type="checkbox" ng-model="activate" id="activate" ng-change="sameAsAbove(first, second); value = null"> ACTIVATE <br />
<input type="text" ng-model="value.first" ng-disabled="!activate">
<input type="text" ng-model="value.second" ng-disabled="!activate">

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') {
$scope.size = 'small';
}
}
})
<link href="http://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.3.5/css/bootstrap.css" rel="stylesheet" />
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myapp">
<div ng-controller="MainCtrl">
<div>
<input ng-model="size" value="large" type="radio" name="button">Large
<input ng-model="size" value="medium" type="radio" name="button">medium
<input ng-model="size" value="small" type="radio" name="button">Small
</div>
<div>
<!--ng-click="fieldClicked(div.size)" in template-->
<div class="col-xs-12 field" ng-click="fieldClicked('col-xs-12')">first</div>
<br/>
<div class="col-xs-6 field" ng-click="fieldClicked('col-xs-6')">second</div>
<br/>
<div class="col-xs-4 field" ng-click="fieldClicked('col-xs-4')">third</div>
</div>
</div>
</div>
No need of script here, just use label instead of div
var app = angular.module('myapp', [], function() {})
app.controller('MainCtrl', function($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>
</div>
</div>
I try to make disable second field until I do not enter 'Lokesh' in first field for that I have tried below code I am in learning stage of angularjs so please correct me where I am doing mistake.
eg.code
<!DOCTYPE html>
<html>
<script src= "http://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js"></script>
<body>
<p>Enter 'Lokesh' to display last name</p>
<div ng-app="myApp" ng-controller="myCtrl">
<input data-ng-model="firstName"
type="text"
ng-disabled="{if(firstName="lokesh")}"
Last Name: <input type="text" ng-model="lastName"><br>
/>
<script>
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.lastName= "Kumar Gaurav";
});
</script>
</body>
The problem is with the attribute ng-disabled="{if(firstName=" lokesh ")}"
There is no need of using if, you can directly compare the strings.
Update the code as
ng-disabled="firstName=='lokesh'"
Demo
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.0/angular.min.js"></script>
<div ng-app>
<input data-ng-model="firstName" class="span12 editEmail" type="text" placeholder="Type lokesh here" />Last Name:
<input type="text" ng-model="lastName" ng-disabled="firstName!=='lokesh'" />
<br>{{firstName}}
</div>
I'm newbie to angular
My angular controller is:
var chatApp = angular.module('chatApp.controllers', []);
chatApp.controller('loginController', ['$scope', function($scope) {
$scope.user_name="name";
$scope.user_password="name";
}]);
the app.js is:
'use strict';
angular.module('chatApp', [
'ui.router',
'chatApp.filters',
'chatApp.services',
'chatApp.directives',
'chatApp.controllers'
]).config(function($stateProvider, $urlRouterProvider) {
$stateProvider
.state('login', {
url: "/login",
templateUrl: "partials/login.html",
controller : "loginController"
})
});
login.html is:
<div>
<div id="wrapper">
<form name="login-form" class="login-form" action="" method="post">
<div class="header">
<h1>Login Form</h1>
</div>
<div class="content">
<input name="username" type="text" class="input username" placeholder="{{user_name}}" />
<div class="user-icon"></div>
<input name="password" type="password" class="input password" placeholder="{{user_password}}" />
<div class="pass-icon"></div>
</div>
</form>
</div>
I've used stateprovider for routing.
But, it's not showing anything in placeholder. What is the reason?
Solved the problem using ng-model instead of {{}}.
<div class="content">
<input name="username" type="text" class="input username" placeholder="username" ng-model="user_name" />
<div class="user-icon"></div>
<input name="password" type="password" class="input password" placeholder="password" ng-model="user_password"/>
<div class="pass-icon"></div>
</div>
This works for me if I say ng-controller = "loginController" in the html-
<div ng-controller = 'loginController'>
<div id="wrapper">
<form name="login-form" class="login-form" action="" method="post">
<div class="header">
<h1>Login Form</h1>
</div>
<div class="content">
<input name="username" type="text" class="input username" placeholder="{{user_name}}" />
<div class="user-icon"></div>
<input name="password" type="password" class="input password" placeholder="{{user_password}}" />
<div class="pass-icon"></div>
</div>
</div>
Here's a JSBin with it working: http://jsbin.com/aDuJIku/265/edit?html,js,output
This solution doesn't include ui-router, but it should work with it.
Try this:
var chatApp = angular.module('chatApp.controllers', []);
chatApp.controller('loginController', ['$scope','$timeout', function($scope,$timeout) {
$timeout(function(){
$scope.user_name="name";
$scope.user_password="name";
},100);
}]);
you just have to change to RouteProvider, In your case you just do:
angular.module('chatApp', [ 'ngRoute' 'ui.router','chatApp.filters','chatApp.services', 'chatApp.directives', 'chatApp.controllers'])
.config(function($routeProvider) {
$routeProvider.when('/login', { templateUrl: "partials/login.html", controller: "loginController" })
});
please make sure that you have angular-route js included.
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.11/angular.min.js"></script>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.11/angular-route.js"></script>
Hope this help you! ;)
Here's some examples for you this
Below mentioned code works.
Note: If somebody tries to run this code in preview its not going to work. JS and HTML code needs to be copied in separate file and use the names mentioned.
var myContrlApp = angular.module('ContrlApp', []);
myContrlApp.controller('MainController', function ($scope) {
var person = {
firstName: "Keith",
lastName: "Jackson",
};
$scope.message = "Welcome, Angular !";
$scope.person = person;
});
