Regexp Help In Js

[skaterdav85]

I've created a regular expression using a positive lookbehind and I've tested it on this RE test site: http://gskinner.com/RegExr/ It's valid and it works, but when I try and create a regexp object in JS using that same expression, I get an error.

var re = /(?<=beans.\sTotal\s=\s)[0-9]*/g;

Chrome Console Error: Uncaught SyntaxError: Invalid regular expression: /(?<=beans.\sTotal\s=\s)[0-9]*/: Invalid groupJS Bin Error: Line 1: var re = /(?<=beans.\sTotal\s=\s)[0-9]*/g; --- Expected ':' and instead saw '<'.

That test site runs the expressions in Actionscript, not Javascript. http://blog.stevenlevithan.com/archives/mimic-lookbehind-javascript
