javascript - Replace last occurrence of character in string

Question

Is there an easy way in javascript to replace the last occurrence of an '_' (underscore) in a given string?

Answer 1

You don't need jQuery, just a regular expression.

This will remove the last underscore:

var str = 'a_b_c';
console.log(  str.replace(/_([^_]*)$/, '$1')  ) //a_bc
