Question

I need to grab the value of a variale found in a javascript file. Using xmlhttprequest I can get the page’s source, however, I need a regular expression to grab the value of a few variables located within the file.

I want to grab the value of a variable:

var VARIABLE_NAME = VALUE

I tried this regular expression:

/var VARIABLE_NAME \=/

But I think I am missing what needs to be done for getting what’s after the equal sign.

Answer 1

Try:

regex = /VARIABLE_NAME=(.*)/;
alert(yourText.match(regex)[1]);
