Razor view escape @ sign in regular expression

Question

IN MVC Razor view i am writing a regular expression to detect URL in text. Expression is

var exp = /(\b(https?|ftp|file):\/\/[-A-Z0-9+&@#\/%?=~_|!:,.;]*[-A-Z0-9+&@#\/%=~_|])/ig;

But MVC is showing error on each @ sign , how can i escape to avoid error ?

Answer 1

You can use @@ to escape @

var exp = /(\b(https?|ftp|file):\/\/[-A-Z0-9+&@@#\/%?=~_|!:,.;]*[-A-Z0-9+&@@#\/%=~_|])/ig;

The html output will contain single @:

<script type="text/javascript">
        var exp = /(\b(https?|ftp|file):\/\/[-A-Z0-9+&@#\/%?=~_|!:,.;]*[-A-Z0-9+&@#\/%=~_|])/ig;
</script>
