String operations with javascript

I would like to take the url which would be something along the lines of http://blahblahblah.com…&substring=CH+BH+LH

and then extract everything after the ‘&’, remove the ‘CH+’ and then put this new string into a field called “subform” using javascript.

can someone help me out with this code? Thanks

Take a look at the javascript indexOf and substring functions

You might also look at regular expressions, e.g.:

var myURL = “http://blahblahblah.com/something&CH+BH+LH”;

var re1 = new RegExp(“^.+&”); // any characters followed by “&”

var temp = myURL.replace(re1,“”); // replace that string with “”

alert(temp); // will show “CH+BH+LH”
