Highlighting links in text using “linky” filter
At times we come across few cases where we need to differentiate the links amongst the plain text. Angular provide us with a very useful filter named : “linky” which help us to do so.
With the help of linky filter we can detect links from text and show them differently . Linky takes text and produces HTML by wrapping all URLs into anchor tags. It supports email address , http, https, and mailto.
For this you would require the ngSanitize module in angular app.
In HTML binding
<p ng-bind-html=”myText | linky”> </p>
You can also define the target for high-lighted links like this-
<p ng-bind-html=”myText | linky :’_blank'”>
[js]
<!DOCTYPE html>
<html>
<head lang="en">
<meta charset="UTF-8">
<title>Lets try linky filter</title>
<script type="application/javascript" src="angular.js"></script>
<script src="LinkyCtrl.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.2.1/angular-sanitize.min.js"></script>
</head>
<body>
<div ng-app="myApp" ng-controller="myController">
<div>
<p ng-bind-html="myText | linky :’_blank’"></p>
<textarea ng-model="myText" style="width: 420px; height: 120px"></textarea>
</div>
</div>
</body>
</html>
[/js]
In our angular controller,
[js]
var myApp = angular.module(‘myApp’, [‘ngSanitize’])
.controller(‘myController’, [‘$scope’, function ($scope) {
$scope.myText = "Some default text is here http://www.intelligrape.com/";
}]);
[/js]
So in this way we can quickly highlight the links in angular.
Hope this helps.
