When using ng-bind-html in AngularJS, you may encounter an error related to the use of untrusted content or the $sce:unsafe error. This error occurs when you are trying to bind HTML that has not been explicitly marked as safe by the Strict Contextual Escaping (SCE) mechanism in AngularJS.

The $sce:unsafe error is a security feature in AngularJS that helps prevent the injection of potentially harmful content into your application. It's crucial to ensure that any HTML you bind with ng-bind-html is considered safe to use.

To fix the $sce:unsafe error, you can use the $sce.trustAsHtml() function to explicitly mark the HTML content as trusted. This tells AngularJS that you are aware of the potential risks and have verified that the HTML is safe to use.

Here's how you can use $sce.trustAsHtml() in your AngularJS controller or directive:

  1. Inject the $sce service into your controller or directive:
javascript
angular.module('myApp').controller('MyController', ['$scope', '$sce', function($scope, $sce) { // Controller code here }]);
  1. Trust the HTML content using $sce.trustAsHtml():
javascript
angular.module('myApp').controller('MyController', ['$scope', '$sce', function($scope, $sce) { $scope.htmlContent = '<p>Hello, <b>AngularJS</b>!</p>'; $scope.trustedHtmlContent = $sce.trustAsHtml($scope.htmlContent); }]);
  1. Use the trusted HTML in your view with ng-bind-html:
html
<div ng-controller="MyController"> <div ng-bind-html="trustedHtmlContent"></div> </div>

By using $sce.trustAsHtml(), you are explicitly telling AngularJS that the HTML content is safe, and the $sce:unsafe error should no longer occur.

However, it's important to be cautious when using $sce.trustAsHtml(). Only trust HTML content from trusted sources, as injecting untrusted content can lead to security vulnerabilities in your application. Always sanitize and validate the content before using $sce.trustAsHtml(). If you need to display user-generated content, consider using AngularJS's built-in $sanitize service or a dedicated HTML sanitization library to ensure that the content is safe to display.
