Is there a way to efficiently remove certain elements from the DOM after they have been added by this code snippet?
<div ng-bind-html-unsafe="whatever"></div>
I have created a function to remove these elements, but I am unsure how to trigger it after the completion of ng-bind-html-unsafe. Are there any callbacks available for ng-bind-html-unsafe or is there a more optimal approach?
The ng-bind-html-unsafe feature has been deprecated in the latest version (1.2+) of angular. It is recommended to use the $sanitize service in the updated angular version. To do this, you will need to include the sanitize library and integrate it into your module.
By implementing the sanitize operation in this way, you can freely perform any desired actions once the text has been cleaned without needing a callback function.
Here is a simple implementation example:
<!doctype html>
<html lang="en">
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.11/angular.js"></script>
<script src="libs/angular/angular-sanitize.js"></script>
</head>
<body ng-app="myApp">
<div ng-controller="myController">
<div>{{sanitized}}</div>
</div>
<script>
angular.module('myApp', ['ngSanitize'])
.controller('myController', ['$scope', '$sanitize', function($scope, $sanitize) {
$scope.sanitized = $sanitize('someTextFromSomeSource');
// Perform further actions with the sanitized text here
}])
</script>
</body>
</html>
To enhance the functionality of your demo, I suggest moving the HTML into a custom directive:
<div ng-bind-html-unsafe="whatever"></div>
Within the directive, you can dynamically manipulate the HTML content based on specific requirements. To achieve this, you can implement a $watch listener on the 'whatever' variable like so:
$scope.$watch('whatever',function(newValue,oldValue, scope){
//perform necessary actions
});
This code can be encapsulated within the new directive, and it may be beneficial to utilize the postLink function for better organization.
For further information on Angular directives, refer to the official Angular Documentation.
