How to remove extra white spaces using javascript or jquery?

Question

I got HTML element contains this:

    
  P6C245RO 
         


        

Answer 1

element.text().replace(/\s+/g, " ");

This uses a regular expression (/.../) to search for one or more (+) whitespace characters (\s) throughout the element's text (g, the global modifier, which finds all matches rather than stopping after the first match) and replace each with one space (" ").
