Trim spaces from start and end of string

Question

I am trying to find a way to trim spaces from the start and end of the title string. I was using this, but it doesn\'t seem to be working:

title = title.repl         


        

Answer 1

Here, this should do all that you need

function doSomething(input) {
    return input
              .replace(/^\s\s*/, '')     // Remove Preceding white space
              .replace(/\s\s*$/, '')     // Remove Trailing white space
              .replace(/([\s]+)/g, '-'); // Replace remaining white space with dashes
}

alert(doSomething("  something with  some       whitespace   "));

Answer 2

jQuery.trim(" hello, how are you? ");
