Hi,

Is there a trim() function in Javascript? I am trying to find one, can anybody give me a hand?

String.prototype.trim = function() {
return this.replace(/^\s+/,'').replace(/\s+$/,'');
}

Now:

' hello '.trim() == 'hello'

:)

Umm, assuming that code was declared elsewhere in the page:

onblur="this.value = this.value.trim()"
