使用jQuery替换最后一个逗号？

Question

http://jsbin.com/uxepap/3/edit

Here is div with links inside. I'm trying to replace comma inside last <a> with point "."

This comma comes from numeral sort of the list, should be replaced with point.

The problem is, all links stored inside links var, not sure how to get the last one and then replace it.

Any thoughts?

Answer 1

Use String.replace

var links = $('a');

var $last = links.filter(":last");

$last.html( $last.html().replace(",", "."));

Answer 2

links.eq(-1).html(function(index, value) {
  return value.replace(/,\s*$/, ".");
});
