how to take last character out of string if character is a space... 1

[spewn]

basically, i know who to check each character using charAt(i), where i equals a progressive number.

but how do i remove individual elements of the string?

any help?

function removeChar(pos)
{
  this = this.substring(0,pos-1) + this.substring(pos, this.length);
}
String.prototype.removeChar = removeChar;

Put this somewhere on your page, and call:

var teststr = "abcdefghij";
teststr.removeChar(5);
alert(teststr) // alerts "abcdfghij"

Or, you could do:

var str = "hello there";
str.replace( " ", "" );
alert( str );

Or, answering the topic, to remove the last character of a string only if it is a space, you could do:

var str = "hey ";
str = (str.charAt(str.length-1) == " ") ? str.slice(0,str.length-1) : str;
alert (str);

hope that helps

Then may I continue on this crusade to help by suggestion a shorter line:

str = (str.charAt(str.length-1) == " ") ? str.slice(0,[blue]-1[/blue]) : str;

Nice.

Forgot about that negative number thing.

Or to answer the topic (again):

str = str.replace(/( )$/,"");

If we're trying to do tighter code , why not just do:

str = str.replace(/\s$/,"");

Yeah, it is one character shorter. LOL.

Though I kinda prefer

if (str.charAt(str.length-1)=" ") str=str.slice(0,-2);

... since it would seem to execute faster -- only a simple test on the last position, and only if needed does it do a complete string value replacement (which could be relatively slower if it's a long string).

That's my 2 cents worth.
