call function inside $sce.trustAsHtml() string in Angular js
I am developing an app using Angularjs and adding HTML
using $sce.trustAsHtml()
in my page. I want to call a function in above dynamically added content. My html and script as below.
HTML
<div ng-app="ngBindHtmlExample">
<div ng-controller="ngBindHtmlCtrl">
<p ng-bind-html="myHTML"></p>
</div>
</div>
Javascript
angular.module('ngBindHtmlExample', ['ngSanitize'])
.controller('ngBindHtmlCtrl', ['$scope','$sce', function ngBindHtmlCtrl($scope, $sce) {
$scope.myHTML =$sce.trustAsHtml(
'I am an <code>HTML</code>string with <a href="#" ng-mouseover="removeExp()">links!</a> and other <em>stuff</em>');
$scope.removeExp = function (){
console.log('dfdfgdfgdfg');
}
}]);

Solution 1:
It's a bit tricky because ng-bind-html
will simply insert plain old html and not bother compiling it (so any directives in the html will not be processed by angular.
The trick is finding a way to compile whenever the template changes. For example, you could create a directive that does this. It would look something like:
.directive('compileTemplate', function($compile, $parse){
return {
link: function(scope, element, attr){
var parsed = $parse(attr.ngBindHtml);
function getStringValue() { return (parsed(scope) || '').toString(); }
//Recompile if the template changes
scope.$watch(getStringValue, function() {
$compile(element, null, -9999)(scope); //The -9999 makes it skip directives so that we do not recompile ourselves
});
}
}
});
You can then use it like this:
<p ng-bind-html="myHTML" compile-template></p>
