how to use trim() in javascript

i used the bolow example.. none of it is worinking for trimming white spaces

[CODE=javascript] var a = String.trim(" Visit W3Schools ");
alert(a)


var sMyVar = new String (" testing trim ");
alert(sMyVar.tr im());


var str = " blah blah ";
var trimmed = str.replace(/^\s+|\s+$/g, '') ;
alert(trimmed);
alert(trimmed.v alue.length);
q=str.trim();
alert(q);
alert("'" + str.trim() + "'");[/CODE]

all my need is to take off white spaces before and after a string but not inbetween a string.. ie.,
'' babe babe " should be ''babe babe"......

any help..
thanks in advance..
regards.

Just a note that JavaScript strings don't have a trim() method, though you can add it using String.prototyp e.

[mrhoo]

this method removes leading and trailing whitespace from a string.
The second replace replaces multiple consecutive spaces (but not tabs or newlines) with single spaces-
take it out if you don't want that behavior.

[CODE=javascript]String.prototyp e.clean:functio n(){
var str= this.replace(/(^\s+)|(\s+$)/g,'');
return str.replace(/ {2,}/g,' ');
}[/CODE]
