Is it possible to create an HTML fragment in an AngularJS controller and have this HTML shown in the view?
This comes from a requirement to turn an inconsistent JSON blob into a nested list of id: value pairs. Therefore the HTML is created in the controller and I am now looking to display it.
I have created a model property, but cannot render this in the view without it just printing the HTML.
Update
It appears that the problem arises from angular rendering the created HTML as a string within quotes. Will attempt to find a way around this.
Example controller :
var SomeController = function () {
this.customHtml = '<ul><li>render me please</li></ul>';
}
Example view :
<div ng:bind="customHtml"></div>
Gives :
<div>
"<ul><li>render me please</li></ul>"
</div>
For Angular 1.x, use ng-bind-html in the HTML:
<div ng-bind-html="thisCanBeusedInsideNgBindHtml"></div>
At this point you would get a attempting to use an unsafe value in a safe context error so you need to either use ngSanitize or $sce to resolve that.
$sce
Use $sce.trustAsHtml() in the controller to convert the html string.
$scope.thisCanBeusedInsideNgBindHtml = $sce.trustAsHtml(someHtmlVar);
ngSanitize
There are 2 steps:
include the angular-sanitize.min.js resource, i.e.:
<script src="lib/angular/angular-sanitize.min.js"></script>
In a js file (controller or usually app.js), include ngSanitize, i.e.:
angular.module('myApp', ['myApp.filters', 'myApp.services',
'myApp.directives', 'ngSanitize'])
You can also create a filter like so:
var app = angular.module("demoApp", ['ngResource']);
app.filter("trust", ['$sce', function($sce) {
return function(htmlCode){
return $sce.trustAsHtml(htmlCode);
}
}]);
Then in the view
<div ng-bind-html="trusted_html_variable | trust"></div>
Note: This filter trusts any and all html passed to it, and could present an XSS vulnerability if variables with user input are passed to it.
Angular JS shows HTML within the tag
The solution provided in the above link worked for me, none of the options on this thread did. For anyone looking for the same thing with AngularJS version 1.2.9
Here's a copy:
Ok I found solution for this:
JS:
$scope.renderHtml = function(html_code)
{
return $sce.trustAsHtml(html_code);
};
HTML:
<p ng-bind-html="renderHtml(value.button)"></p>
EDIT:
Here's the set up:
JS file:
angular.module('MyModule').controller('MyController', ['$scope', '$http', '$sce',
function ($scope, $http, $sce) {
$scope.renderHtml = function (htmlCode) {
return $sce.trustAsHtml(htmlCode);
};
$scope.body = '<div style="width:200px; height:200px; border:1px solid blue;"></div>';
}]);
HTML file:
<div ng-controller="MyController">
<div ng-bind-html="renderHtml(body)"></div>
</div>
Fortunately, you don't need any fancy filters or unsafe methods to avoid that error message. This is the complete implementation to properly output HTML markup in a view in the intended and safe way.
The sanitize module must be included after Angular:
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.2.26/angular.js"></script>
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.2.26/angular-sanitize.js"></script>
Then, the module must be loaded:
angular.module('app', [
'ngSanitize'
]);
This will allow you to include markup in a string from a controller, directive, etc:
scope.message = "<strong>42</strong> is the <em>answer</em>.";
Finally, in a template, it must be output like so:
<p ng-bind-html="message"></p>
Which will produce the expected output: 42 is the answer.
I have tried today, the only way I found was this
<div ng-bind-html-unsafe="expression"></div>
ng-bind-html-unsafe no longer works.
This is the shortest way:
Create a filter:
myApp.filter('unsafe', function($sce) { return $sce.trustAsHtml; });
And in your view:
<div ng-bind-html="customHtml | unsafe"></div>
P.S. This method doesn't require you to include the ngSanitize module.
on html
<div ng-controller="myAppController as myCtrl">
<div ng-bind-html-unsafe="myCtrl.comment.msg"></div>
OR
<div ng-bind-html="myCtrl.comment.msg"></div
on controller
mySceApp.controller("myAppController", function myAppController( $sce) {
this.myCtrl.comment.msg = $sce.trustAsHtml(html);
works also with $scope.comment.msg = $sce.trustAsHtml(html);
I found that using ng-sanitize did not allow me to add ng-click in the html.
To solve this I added a directive. Like this:
app.directive('htmldiv', function($compile, $parse) {
return {
restrict: 'E',
link: function(scope, element, attr) {
scope.$watch(attr.content, function() {
element.html($parse(attr.content)(scope));
$compile(element.contents())(scope);
}, true);
}
}
});
And this is the HTML:
<htmldiv content="theContent"></htmldiv>
Good luck.
Just did this using ngBindHtml by following angular(v1.4) docs,
<div ng-bind-html="expression"></div>
and expression can be "<ul><li>render me please</li></ul>"
Make sure you include ngSanitize in the module's dependencies.
Then it should work fine.
Another solution, very similar to blrbr's except using a scoped attribute is:
angular.module('app')
.directive('renderHtml', ['$compile', function ($compile) {
return {
restrict: 'E',
scope: {
html: '='
},
link: function postLink(scope, element, attrs) {
function appendHtml() {
if(scope.html) {
var newElement = angular.element(scope.html);
$compile(newElement)(scope);
element.append(newElement);
}
}
scope.$watch(function() { return scope.html }, appendHtml);
}
};
}]);
And then
<render-html html="htmlAsString"></render-html>
Note you may replace element.append() with element.replaceWith()
there is one more solution for this problem using creating new attribute or directives in angular.

};
});
index.html
<div>

</div>
or
<div product-specs>//it will add product-specs.html file
or
<div ng-include="product-description.html"></div>
https://docs.angularjs.org/guide/directive
you can also use ng-include.
<div class="col-sm-9 TabContent_container" ng-include="template/custom.html">
</div>
you can use "ng-show" to show hide this template data.
here is the solution make a filter like this
.filter('trusted',
function($sce) {
return function(ss) {
return $sce.trustAsHtml(ss)
};
}
)
and apply this as a filter to the ng-bind-html like
<div ng-bind-html="code | trusted">
and thank to Ruben Decrop
Use
<div ng-bind-html="customHtml"></div>
and
angular.module('MyApp', ['ngSanitize']);
For that, you need to include angular-sanitize.js,
for example in your html-file with
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.0/angular-sanitize.js"></script>
Here's a simple (and unsafe) bind-as-html directive, without the need for ngSanitize:
myModule.directive('bindAsHtml', function () {
return {
link: function (scope, element, attributes) {
element.html(scope.$eval(attributes.bindAsHtml));
}
};
});
Note that this will open up for security issues, if binding untrusted content.
Use like so:
<div bind-as-html="someHtmlInScope"></div>
Working example with pipe to display html in template with Angular 4.
1.Crated Pipe escape-html.pipe.ts
`
import { Pipe, PipeTransform } from '#angular/core';
import { DomSanitizer } from '#angular/platform-browser';
#Pipe({name : 'keepHtml', pure : false})
export class EscapeHtmlPipe implements PipeTransform{
constructor(private sanitizer : DomSanitizer){
}
transform(content){
return this.sanitizer.bypassSecurityTrustHtml(content);
}
}
`
2. Register pipe to app.module.ts
import {EscapeHtmlPipe} from './components/pipes/escape-html.pipe';
declarations: [...,EscapeHtmlPipe]
Use in your template
<div class="demoPipe" [innerHtml]="getDivHtml(obj.header) | keepHtml">
getDivHtml() { //can return html as per requirement}
Please add appropriate implementation for getDivHtml in associated component.ts file.
Just simple use [innerHTML], like below:
<div [innerHTML]="htmlString"></div>
Before you needed to use ng-bind-html...
I want to bind an array (customLayers) and use it for ng-repeat.
I fill the array inside the kv.colorMap Object.
I have three directives using these technique. But the directive updates the binded array on view ONLY after pressing a functionless button (checkResult), which is inside this directive.
Directive Template Code:
...
<div class="createInfo colorExprContainer">
<div ng-repeat="layer in customLayers">{{layer.color}}</div>
</div>
<div class="buttonWrapper text-center">
<button class="btn" ng-click="checkResult()">Ergebnis prüfen</button>
</div>
...
Directive JavaScript Code:
app.directive('boolKv', function($parse, $timeout){
return {
restrict: 'E',
replace:true,
scope:true,
templateUrl: "directives/boolKV/boolKV.html",
link: function($scope, $element, $attr) {
...
var kv = new BAKV({target: cv[0].id, expr: expr});
$scope.customLayers = kv.colorMap.layers;
...
$scope.checkResult = function(){console.log("it works!");};
});
Does someone have an idea?
Thank you very much!
Thank you MirMasej!
You were right, I was calling it after render. Maybe because I've used the EaselJs Library for canvas. I wanted to get the update after click on a block inside this canvas.
I solved it by adding, if someone has a better idea I would try it:
kv.colorMap.onChangedLayer = function(layer) {
$timeout(function(){
$scope.$apply();
});
};
Im calling this onChangedLayer event after changing the data inside the colorMap object.
The Situation
Nested within our Angular app is a directive called Page, backed by a controller, which contains a div with an ng-bind-html-unsafe attribute. This is assigned to a $scope var called 'pageContent'. This var gets assigned dynamically generated HTML from a database. When the user flips to the next page, a called to the DB is made, and the pageContent var is set to this new HTML, which gets rendered onscreen through ng-bind-html-unsafe. Here's the code:
Page directive
angular.module('myApp.directives')
.directive('myPage', function ($compile) {
return {
templateUrl: 'page.html',
restrict: 'E',
compile: function compile(element, attrs, transclude) {
// does nothing currently
return {
pre: function preLink(scope, element, attrs, controller) {
// does nothing currently
},
post: function postLink(scope, element, attrs, controller) {
// does nothing currently
}
}
}
};
});
Page directive's template ("page.html" from the templateUrl property above)
<div ng-controller="PageCtrl" >
...
<!-- dynamic page content written into the div below -->
<div ng-bind-html-unsafe="pageContent" >
...
</div>
Page controller
angular.module('myApp')
.controller('PageCtrl', function ($scope) {
$scope.pageContent = '';
$scope.$on( "receivedPageContent", function(event, args) {
console.log( 'new page content received after DB call' );
$scope.pageContent = args.htmlStrFromDB;
});
});
That works. We see the page's HTML from the DB rendered nicely in the browser. When the user flips to the next page, we see the next page's content, and so on. So far so good.
The Problem
The problem here is that we want to have interactive content inside of a page's content. For instance, the HTML may contain a thumbnail image where, when the user clicks on it, Angular should do something awesome, such as displaying a pop-up modal window. I've placed Angular method calls (ng-click) in the HTML strings in our database, but of course Angular isn't going to recognize either method calls or directives unless it somehow parses the HTML string, recognizes them and compiles them.
In our DB
Content for Page 1:
<p>Here's a cool pic of a lion. <img src="lion.png" ng-click="doSomethingAwesone('lion', 'showImage')" > Click on him to see a large image.</p>
Content for Page 2:
<p>Here's a snake. <img src="snake.png" ng-click="doSomethingAwesone('snake', 'playSound')" >Click to make him hiss.</p>
Back in the Page controller, we then add the corresponding $scope function:
Page controller
$scope.doSomethingAwesome = function( id, action ) {
console.log( "Going to do " + action + " with "+ id );
}
I can't figure out how to call that 'doSomethingAwesome' method from within the HTML string from the DB. I realize Angular has to parse the HTML string somehow, but how? I've read vague mumblings about the $compile service, and copied and pasted some examples, but nothing works. Also, most examples show dynamic content only getting set during the linking phase of the directive. We would want Page to stay alive throughout the life of the app. It constantly receives, compiles and displays new content as the user flips through pages.
In an abstract sense, I guess you could say we are trying to dynamically nest chunks of Angular within an Angular app, and need to be able to swap them in and out.
I've read various bits of Angular documentation multiple times, as well as all sorts of blog posts, and JS Fiddled with people's code. I don't know whether I'm completely misunderstanding Angular, or just missing something simple, or maybe I'm slow. In any case, I could use some advice.
ng-bind-html-unsafe only renders the content as HTML. It doesn't bind Angular scope to the resulted DOM. You have to use $compile service for that purpose. I created this plunker to demonstrate how to use $compile to create a directive rendering dynamic HTML entered by users and binding to the controller's scope. The source is posted below.

ele.html(html);
$compile(ele.contents())(scope);
});
}
};
});
function MyController($scope) {
$scope.click = function(arg) {
alert('Clicked ' + arg);
}
$scope.html = '<a ng-click="click(1)" href="#">Click me</a>';
}
In angular 1.2.10 the line scope.$watch(attrs.dynamic, function(html) { was returning an invalid character error because it was trying to watch the value of attrs.dynamic which was html text.
I fixed that by fetching the attribute from the scope property
scope: { dynamic: '=dynamic'},
My example
angular.module('app')
.directive('dynamic', function ($compile) {
return {
restrict: 'A',
replace: true,
scope: { dynamic: '=dynamic'},
link: function postLink(scope, element, attrs) {
scope.$watch( 'dynamic' , function(html){
element.html(html);
$compile(element.contents())(scope);
});
}
};
});
Found in a google discussion group. Works for me.
var $injector = angular.injector(['ng', 'myApp']);
$injector.invoke(function($rootScope, $compile) {
$compile(element)($rootScope);
});
You can use
ng-bind-html https://docs.angularjs.org/api/ng/service/$sce
directive to bind html dynamically.
However you have to get the data via $sce service.
Please see the live demo at http://plnkr.co/edit/k4s3Bx
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope,$sce) {
$scope.getHtml=function(){
return $sce.trustAsHtml("<b>Hi Rupesh hi <u>dfdfdfdf</u>!</b>sdafsdfsdf<button>dfdfasdf</button>");
}
});
<body ng-controller="MainCtrl">
<span ng-bind-html="getHtml()"></span>
</body>
Try this below code for binding html through attr
.directive('dynamic', function ($compile) {
return {
restrict: 'A',
replace: true,
scope: { dynamic: '=dynamic'},
link: function postLink(scope, element, attrs) {
scope.$watch( 'attrs.dynamic' , function(html){
element.html(scope.dynamic);
$compile(element.contents())(scope);
});
}
};
});
Try this element.html(scope.dynamic);
than element.html(attr.dynamic);
Is it possible to create an HTML fragment in an AngularJS controller and have this HTML shown in the view?
This comes from a requirement to turn an inconsistent JSON blob into a nested list of id: value pairs. Therefore the HTML is created in the controller and I am now looking to display it.
I have created a model property, but cannot render this in the view without it just printing the HTML.
Update
It appears that the problem arises from angular rendering the created HTML as a string within quotes. Will attempt to find a way around this.
Example controller :
var SomeController = function () {
this.customHtml = '<ul><li>render me please</li></ul>';
}
Example view :
<div ng:bind="customHtml"></div>
Gives :
<div>
"<ul><li>render me please</li></ul>"
</div>
For Angular 1.x, use ng-bind-html in the HTML:
<div ng-bind-html="thisCanBeusedInsideNgBindHtml"></div>
At this point you would get a attempting to use an unsafe value in a safe context error so you need to either use ngSanitize or $sce to resolve that.
$sce
Use $sce.trustAsHtml() in the controller to convert the html string.
$scope.thisCanBeusedInsideNgBindHtml = $sce.trustAsHtml(someHtmlVar);
ngSanitize
There are 2 steps:
include the angular-sanitize.min.js resource, i.e.:
<script src="lib/angular/angular-sanitize.min.js"></script>
In a js file (controller or usually app.js), include ngSanitize, i.e.:
angular.module('myApp', ['myApp.filters', 'myApp.services',
'myApp.directives', 'ngSanitize'])
You can also create a filter like so:
var app = angular.module("demoApp", ['ngResource']);
app.filter("trust", ['$sce', function($sce) {
return function(htmlCode){
return $sce.trustAsHtml(htmlCode);
}
}]);
Then in the view
<div ng-bind-html="trusted_html_variable | trust"></div>
Note: This filter trusts any and all html passed to it, and could present an XSS vulnerability if variables with user input are passed to it.
Angular JS shows HTML within the tag
The solution provided in the above link worked for me, none of the options on this thread did. For anyone looking for the same thing with AngularJS version 1.2.9
Here's a copy:
Ok I found solution for this:
JS:
$scope.renderHtml = function(html_code)
{
return $sce.trustAsHtml(html_code);
};
HTML:
<p ng-bind-html="renderHtml(value.button)"></p>
EDIT:
Here's the set up:
JS file:
angular.module('MyModule').controller('MyController', ['$scope', '$http', '$sce',
function ($scope, $http, $sce) {
$scope.renderHtml = function (htmlCode) {
return $sce.trustAsHtml(htmlCode);
};
$scope.body = '<div style="width:200px; height:200px; border:1px solid blue;"></div>';
}]);
HTML file:
<div ng-controller="MyController">
<div ng-bind-html="renderHtml(body)"></div>
</div>
Fortunately, you don't need any fancy filters or unsafe methods to avoid that error message. This is the complete implementation to properly output HTML markup in a view in the intended and safe way.
The sanitize module must be included after Angular:
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.2.26/angular.js"></script>
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.2.26/angular-sanitize.js"></script>
Then, the module must be loaded:
angular.module('app', [
'ngSanitize'
]);
This will allow you to include markup in a string from a controller, directive, etc:
scope.message = "<strong>42</strong> is the <em>answer</em>.";
Finally, in a template, it must be output like so:
<p ng-bind-html="message"></p>
Which will produce the expected output: 42 is the answer.
I have tried today, the only way I found was this
<div ng-bind-html-unsafe="expression"></div>
ng-bind-html-unsafe no longer works.
This is the shortest way:
Create a filter:
myApp.filter('unsafe', function($sce) { return $sce.trustAsHtml; });
And in your view:
<div ng-bind-html="customHtml | unsafe"></div>
P.S. This method doesn't require you to include the ngSanitize module.
on html
<div ng-controller="myAppController as myCtrl">
<div ng-bind-html-unsafe="myCtrl.comment.msg"></div>
OR
<div ng-bind-html="myCtrl.comment.msg"></div
on controller
mySceApp.controller("myAppController", function myAppController( $sce) {
this.myCtrl.comment.msg = $sce.trustAsHtml(html);
works also with $scope.comment.msg = $sce.trustAsHtml(html);
I found that using ng-sanitize did not allow me to add ng-click in the html.
To solve this I added a directive. Like this:
app.directive('htmldiv', function($compile, $parse) {
return {
restrict: 'E',
link: function(scope, element, attr) {
scope.$watch(attr.content, function() {
element.html($parse(attr.content)(scope));
$compile(element.contents())(scope);
}, true);
}
}
});
And this is the HTML:
<htmldiv content="theContent"></htmldiv>
Good luck.
Just did this using ngBindHtml by following angular(v1.4) docs,
<div ng-bind-html="expression"></div>
and expression can be "<ul><li>render me please</li></ul>"
Make sure you include ngSanitize in the module's dependencies.
Then it should work fine.
Another solution, very similar to blrbr's except using a scoped attribute is:
angular.module('app')
.directive('renderHtml', ['$compile', function ($compile) {
return {
restrict: 'E',
scope: {
html: '='
},
link: function postLink(scope, element, attrs) {
function appendHtml() {
if(scope.html) {
var newElement = angular.element(scope.html);
$compile(newElement)(scope);
element.append(newElement);
}
}
scope.$watch(function() { return scope.html }, appendHtml);
}
};
}]);
And then
<render-html html="htmlAsString"></render-html>
Note you may replace element.append() with element.replaceWith()
there is one more solution for this problem using creating new attribute or directives in angular.

and thank to Ruben Decrop
Use
<div ng-bind-html="customHtml"></div>
and
angular.module('MyApp', ['ngSanitize']);
For that, you need to include angular-sanitize.js,
for example in your html-file with
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.0/angular-sanitize.js"></script>
Here's a simple (and unsafe) bind-as-html directive, without the need for ngSanitize:
myModule.directive('bindAsHtml', function () {
return {
link: function (scope, element, attributes) {
element.html(scope.$eval(attributes.bindAsHtml));
}
};
});
Note that this will open up for security issues, if binding untrusted content.
Use like so:
<div bind-as-html="someHtmlInScope"></div>
Working example with pipe to display html in template with Angular 4.
1.Crated Pipe escape-html.pipe.ts
`
import { Pipe, PipeTransform } from '#angular/core';
import { DomSanitizer } from '#angular/platform-browser';
#Pipe({name : 'keepHtml', pure : false})
export class EscapeHtmlPipe implements PipeTransform{
constructor(private sanitizer : DomSanitizer){
}
transform(content){
return this.sanitizer.bypassSecurityTrustHtml(content);
}
}
`
2. Register pipe to app.module.ts
import {EscapeHtmlPipe} from './components/pipes/escape-html.pipe';
declarations: [...,EscapeHtmlPipe]
Use in your template
<div class="demoPipe" [innerHtml]="getDivHtml(obj.header) | keepHtml">
getDivHtml() { //can return html as per requirement}
Please add appropriate implementation for getDivHtml in associated component.ts file.
Just simple use [innerHTML], like below:
<div [innerHTML]="htmlString"></div>
Before you needed to use ng-bind-html...
I would like to use the same HTML template in 3 places, just each time with a different model.
I know I can access the variables from the template, but there names will be different.
Is there a way to pass a model to the ngInclude?
This is what I would like to achieve, of course the attribute add-variable does not work now. Then in my included template, I would acces the detailsObject and its properties.
<pane title="{{projectSummary.ProjectResults.DisplayName}}">
<h2>{{projectSummary.ProjectResults.DisplayName}}</h2>
<ng-include src="'Partials/SummaryDetails.html'" init-variable="{'detailsObject': projectSummary.ProjectResults}"></ng-include>
</pane>
<pane title="Documents" header="true"></pane>
<pane ng-repeat="document in projectSummary.DocumentResults" title="{{document.DisplayName}}">
<h2>{{document.DisplayName}}</h2>
<ng-include src="'Partials/SummaryDetails.html'" add-variable="{'detailsObject': document}"></ng-include>
</pane>
<pane ng-repeat="header in [1]" title="Languages" header="true"></pane>
<pane ng-repeat="language in projectSummary.ResultsByLanguagePairs" title="{{language.DisplayName}}">
<h2>{{document.DisplayName}}</h2>
<ng-include src="'Partials/SummaryDetails.html'" add-variable="{'detailsObject': language}"></ng-include>

If I took a bad approach with using ng-include, is there something else I should try?
There is a rather simple solution, although I must admit, it's not what Misko would recommend. But if creating a directive is an overkill for you and getting Brice's patch is not feasible then the following will help you.
<div ng-repeat="name in ['A']" ng-include="'partial.html'"></div>
<div ng-repeat="name in ['B']" ng-include="'partial.html'"></div>
<script type="text/ng-template" id="partial.html">
<div>{{ name }}</div>
</script>
It's quite evident why it works. See an example here: http://jsfiddle.net/Cndc6/4/
NOTE: this is not my original answer but this is how I'd do this after using angular for a bit.
I would create a directive with the html template as the markup passing in the dynamic data to the directive as seen in this fiddle.
Steps/notes for this example:
Define a directive with markup in the templateUrl and attribute(s) used to pass data into the directive (named type in this example).
Use the directive data in the template (named type in this example).
When using the directive in the markup make sure you pass in the data from the controller scope to the directive (<address-form type="billing"></address-form> (where billing is accessing an object on the controller scope).
Note that when defining a directive the name is camel cased but when used in the markup it is lower case dash delimited (ie it's named addressForm in the js but address-form in the html). More info on this can be found in the angular docs here.
Here is the js:
var myApp = angular.module('myApp',[]);
angular.module('myApp').directive('addressForm', function() {
return {
restrict: 'E',
templateUrl: 'partials/addressform.html', // markup for template
scope: {
type: '=' // allows data to be passed into directive from controller scope
}
};
});
angular.module('myApp').controller('MyCtrl', function($scope) {
// sample objects in the controller scope that gets passed to the directive
$scope.billing = { type: 'billing type', value: 'abc' };
$scope.delivery = { type: 'delivery type', value: 'def' };
});
With markup:
<div ng-controller="MyCtrl">
<address-form type="billing"></address-form>
<address-form type="delivery"></address-form>
</div>
ORIGINAL ANSWER (which is completely different than using a directive BTW).
Note: The fiddle from my original answer below doesn't appear to work anymore due to an error (but keeping it here in case it is still useful)
There was a discussion about this on the Google Group you can see it here.
It looks like this functionality is not supported out of the box but you can use Brice's patch as described in this post.
Here is the sample code from his jsfiddle:
<script id="partials/addressform.html" type="text/ng-template">
partial of type {{type}}<br>
</script>
<div ng-controller="MyCtrl">
<ng-include src="'partials/addressform.html'" onInclude="type='billing'"></ng-include>
<ng-include src="'partials/addressform.html'" onLoad="type='delivery'"></ng-include>
</div>
There is a pull to fix this but it looks like it's dead:
https://github.com/angular/angular.js/pull/1227
Without modifying the Angular source code this will solve the problem in a reusable not-too-hacky-feeling way:
directive('newScope', function() {
return {
scope: true,
priority: 450,
};
});
And an example:
<div new-scope ng-init="myVar = 'one instance'" ng-include="'template.html'"></div>
<div new-scope ng-init="myVar = 'another instance'" ng-include="'template.html'"></div>
Here is a Plunker of it in action:
http://plnkr.co/edit/El8bIm8ta97MNRglfl3n
<div new-scope="myVar = 'one instance'" ng-include="'template.html'"></div>
directive('newScope', function () {
return {
scope: true,
priority: 450,
compile: function () {
return {
pre: function (scope, element, attrs) {
scope.$eval(attrs.newScope);
}
};
}
};
});
This is a directive that combines new-scope from John Culviner's answer with code from Angular's ng-init.
For completeness, this is the Angular 1.2 26 ng-init source, you can see the only change in the new-scope directive is the addition of scope: true
{
priority: 450,
compile: function() {
return {
pre: function(scope, element, attrs) {
scope.$eval(attrs.ngInit);
}
};
}
}
Quick'n'dirty solution:
<div ng-init="details=document||language||projectSummary.ProjectResults">
I hear you! ng-include is not that reusable because it has access to the global scope. It's a little weird.
There should be a way to set local variables. Using a new directive instead of ng-include is a cleaner solution.
The ideal usage looks like:
<div ng-include-template="'Partials/SummaryDetails.html'" ng-include-variables="{ 'detailsObject': language }"></div>
The directive is:
.directive(
'ngIncludeTemplate'
() ->
{
templateUrl: (elem, attrs) -> attrs.ngIncludeTemplate
restrict: 'A'
scope: {
'ngIncludeVariables': '&'
}
link: (scope, elem, attrs) ->
vars = scope.ngIncludeVariables()
for key, value of vars
scope[key] = value
}
)
You can see that the directive doesn't use the global scope. Instead, it reads the object from ng-include-variables and add those members to its own local scope.
It's clean and generic.
