Yes, I suspected it would be possible with regexp, I couldn't quite get the
syntax though

Or you can do it with a RegExp:

String.prototype.trim=String_trim;
function String_trim(){
 return this.replace(/^\s*|\s*$/g, "");
}
var strSomething = "   word   ";
strSomething = strSomething.trim();

strSomething's length is now 4 and it's first character is the 'w'.

length is easy

sMyString.length()

and I've written a trim method:

String.prototype.trim=String_trim;

function String_trim(){
 var i=0;
 var j=this.length;
 while(this.charAt(i)==" ") i++;
 while(this.charAt(j-1)==" ") j--;
 return this.substring(i,j);
}

to invoke it just do

sMyString.trim()

Hi,

I want to trim a string and then check its length(number of characters).
Any idea on how I can do that in JavaScript? 
 
Many thanks

Terrence
