JavaScript replace part of string regex

Question

Hey guys i need to replace a string which starts every time with the same parts. Such as…

var name = $('.item').attr('name'); // Could be »item-name-XYZ« (XYZ) differs each time.
name.replace('item-name-?', 'item-name-newone');

items can appear many times and i do have to replace all names of them. I guess its something with regex…

Thanks in advance.

BTW: My most asked questions are about regex. Does someone has a good source to learn it?

Answer 1

Yes, it is about regex. You can learn them here

Your code will look like this:

name.replace(/item-name-(.*)/, 'item-name-newone');

Answer 2

You don't need regex for this, you can use javascript

var newone = name.substr(0,10) + 'Xyy';
