Hello!

I'm trying to create a super simple regular expression! I just want to assign to a variable everything after an underscore. it will be a counter- number, then and underscore then a fedex or ups tracking code.

var linkId = 3_1Z6656460348661915;

//incomprehensible regular expression magic 

var trackingNumber = 1Z6656460348661915;

var linkId = 3_1Z6656460348661915;
var trackingNumber = linkId.split("_")[0]; // faster than regex
//or with a regex
//var trackingNumber = linkId.match(/_(.*)/)[1]; // kaufmed's illustration ?
