Remove ALL white spaces from text [duplicate]

Replace all spaces in a string with '+'

$("#topNav" + $("#breadCrumb2nd").text().replace(" ", "")).addClass("current");

This is a snippet from my code. I want to add a class to an ID after getting another ID's text property. The problem with this, is the ID holding the text I need, contains gaps between the letters.

I would like the white spaces removed. I have tried TRIM()and REPLACE() but this only partially works. The REPLACE() only removes the 1st space.
