JavaScript 'this' keyword

[nightbandit]

I'm trying to link images with JavaScript. This is what I'm currently doing:

<img src="filepath" alt="alt txt" onClick="window.open(this.src);" />

But I want to have a function to make it easier on myself. Here's what I've tried:

                    [IN HEAD SECTION]

                    function openImg(obj)
                    {
                            window.open(obj.src);
                    }

                    [IN IMG TAG]

                    onClick="openImg(this)"

But it's not working. I'm new to JavaScript so could someone please explain the problem to me, and maybe tell me how to fix it?

The JS you posted looks fine. Check the error console and post relevant error messages here. What browser(s) are you having problems with? Always state the software environment.

I'm using firefox. And the error I'm getting is openImg not defined.

Nevermind I had a typo in my script element, thanks anyays.
