Match @(\w+) and replace in javascript

Question

I\'m trying to match @(\\w+) in a div content and remove it.

Here\'s what i\'ve tried : http://jsfiddle.net/mxgde6m7/1/ .

@(\\w+) works , but it doesn\'t replace

Answer 1

hwnd is correct that you need to double escape \w in your regular expression.

var find = '@(\\w+)';

But, you could also make this code much cleaner by defining a regex literal like so -

var content = document.getElementById('contentbox');
var result = content.innerHTML.replace(/@(\w+)/g, ' ');
alert(result);

Doing it this way doesn't require double escaping, as it's not a string.

Answer 2

Using a RegExp constructor, you need two backslashes \\ in place of each backslash \.

var find = '@(\\w+)';
