HTML
<section>
<div>
<p>{{item}}</p>
</div>
</section>
controller.js
(function () {
var ctrl = function ($scope){
$scope.item = "test";
}
}());
This is my team's project. I cannot change how it is set up. The problem I am trying to solve is inserting the $scope.item into the html. How could I do this?
I added an id _item in section.
<section id="_item">
<div>
<p>{{item}}</p>
</div>
</section>
Write this below code inside the controller.js file.
angular.element(document.getElementById('_item')).append($compile("<div>
<p>{{item}}</p>
</div>")($scope));
Note: add dependency $compile.
I think this will help you.
This is one of the most basic ways to do it.
angular.module('myApp', [])
.controller('myController', function($scope){
$scope.item = 'test'
});
<div ng-app="myApp" ng-controller="myController">
<p>{{item}}</p>
</div>
UPDATE
[app.js]
myApp = angular.module('myApp', []);
[controller.js]
myApp.controller('myController', function($scope){
$scope.item = 'test'
});
Add ng-controller="your_controller_name" to your HTML.
<section ng-controller="myController">
<div>
<p>{{item}}</p>
</div>
</section>
The title of the answer might be missleading. If you really want to append HTML with Angular JS, I think what you need is the ng-bind-html directive
https://docs.angularjs.org/api/ng/directive/ngBindHtml
your html code should be something like
<section>
<div>
<p ng-bind-html="item"></p>
</div>
</section>
the following conf in your controller
.controller('myController','$sce' function($scope, $sce){
$scope.item = $sce.trustAsHtml("<div> this is really appending HTML using AngularJS </div>");
});

Please see below given code:
<div ng-app="myApp" ng-controller="myCtrl">
<p ng-bind-html="myText"></p>
</div>
<script>
var app = angular.module("myApp", ['ngSanitize']);
app.controller("myCtrl", function($scope) {
$scope.myText = "My name is: <h1>John Doe</h1>";
});
</script>
The output is: My Name is:
John Doe
How can i show the text as it is. For example: My Name is : <h1>John Doe</h1>
I want to show the HTML tags on the page.
Please use the $sce of angularjs.
var app = angular.module('myApp', []);
app.controller('MyController', function MyController($scope, $sce) {
$scope.myText = $sce.trustAsHtml("My name is: <h1>John Doe</h1>");
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.3.14/angular.min.js"></script>
<div ng-app="myApp" ng-controller='MyController'>
<p ng-bind-html="myText"></p>
</div>
Reference:
How to use $sce
First create a filter using $sce:
app.filter("html", ['$sce', function($sce) {
return function(input){
return $sce.trustAsHtml(input);
}
}]);
Then:
<div ng-bind-html="myText | html"></div>
Use ng-bind instead ng-bind-html
<div ng-app="myApp" ng-controller="myCtrl">
<p ng-bind="myText"></p>
</div>
Or simply
<p>{{myText}}</p>
I think you should use like this
in your controller
$scope.mytext="<h1>John Doe</h1>"
in you html page
<p ng-bind-html="myText"></p>
I have this
"items" : ["<p>Item 1</p>","<span>Item 2</span>"]
I would like this
<div id="container">
<p>Item 1</p>
<span>Item 2</span>
</div>
How can I do it without using ng-repeat ?
You can use directly like this..
$scope.itemNames = {"items" : ["<p>Item 1</p>","<span>Item 2</span>"]};
<div ng-bind-html-unsafe="itemNames.items"> </div>
or else
use $sce.
.controller('ctrl', ['$scope', '$sce', function ($scope, $sce) {
$scope.itemNames = {"items" : ["<p>Item 1</p>","<span>Item 2</span>"]};
$scope.newNames= $sce.trustAsHtml($scope.itemNames.items);
}]);
<div ng-bind-html="newNames"> </div>
In AngularJS you can use the ng-bind-html directive to print html and for that you must include the $sanitize service.
Now, to pass the array as an html string to the view you can use Array.prototype.join():
angular
.module('App', ['ngSanitize'])
.controller('AppController', ['$scope', function ($scope) {
var obj = {
"items": ["<p>Item 1</p>","<span>Item 2</span>"]
};
$scope.items = obj.items.join('');
}]);
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.10/angular.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular-sanitize/1.5.10/angular-sanitize.min.js"></script>
<div ng-app="App" ng-controller="AppController">
<div id="container" ng-bind-html="items"></div>
</div>
Hi I was just wondering if there is some built-in angular directive (ng-some-directive) that allows you to restrict the scope to a particular model for the desired DOM element.
I belive I have seen something similar done before, but maybe I am thinking of knockout.js
<script>
angular.module('example', [])
.controller('ExampleController', ['$scope', function($scope) {
$scope.heading = 'Some Value';
$scope.complexModel = {...}
}]);
</script>
<div ng-controller="ExampleController">
<h1>{{ heading }}</h1>
<div ng-some-directive='complexModel.to.long.really.annoying'>
<input type='text' ng-model='variable' /> // Actually coming from complexModel.to.long.really.annoying.variable
</div>
</div>
This is a drastically simplified version
Though its not meant for it
<div ng-init='sn = complexModel.to.long.really.annoying'>
<input type='text' ng-model='sn' />
</div>
I have some html-code
<div ng-controller="aboutController">
<p ng-repeat="name in about">
{{about.name}}
{{about.surname}}
</p>
</div>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.15/angular.min.js"></script>
<script>
var myApp = angular.module('myApp', []);
myApp.controller('aboutController', function($scope, $http) {
$http.get('about.json').success(function(data) {
console.log('this is data:',data);
$scope.about = data;
});
});
</script>
what which derective I must to write, simply to insert data from a json-file without repeating them?
You don't need any directive. Just remove ngRepeat and use
<p>
{{about.name}}
{{about.surname}}
</p>
ngRepeat is generally used with collection.
The ngRepeat directive instantiates a template once per item from a collection.
problem is "about." try as "name."
Try as below:
<p ng-repeat="name in about">
{{name.name}}
{{name.surname}}
</p>
I'm trying to get a tag to fire the ng-change event but to no avail. The purpose is to watch changes to post.content. The code is pretty straightforward and parts of it are omitted for brevity, but it's basically a ng-template that is repeated like so:
<li ng-repeat="post in posts" data-id="[[post.id]]" data-rank="[[post.sortrank]]" class="post">
<ng-include src="post.template"></ng-include>
</li>
The repeated template:
<script type="text/ng-template" id="postText.html">
<pre ng-blur="savePost($event, post)" ng-change="changePost()" ng-model="post.content" class="postText" contenteditable="true">[[post.content]]</pre>
</script>
The JS:
$scope.savePost = function($event, post) { //This fires correctly
console.log($event);
console.log(post);
};
$scope.changePost = function() { //This doesn't fire at all
console.log("changed!");
};
Can this be because of the contenteditable attribute? Because I can get the ngChange examples working on the Angular tutorial site.
You can use akatov's angular-contenteditable.js.
From the docs... JS:
angular.module('myapp', ['contenteditable'])
.controller('Ctrl', ['$scope', function($scope) {
$scope.model="<i>interesting</i> stuff"
}])
HTML:
<div ng-controller="Ctrl">
<span contenteditable="true"
ng-model="model"
strip-br="true"
select-non-editable="true">
</span>
</div>
