Something like this ought to do it pretty nicely.

<img id="img" src="" class="moz-txt-link-rfc2396E" href="http://www.google.com.au/intl/en_au/images/logo.gif">"http://www.google.com.au/intl/en_au/images/logo.gif">

<script>
    alert(document.getElementById('img').width);
    function resize(img,xIncrement,yIncrement,maxWidth) {
        img.width += xIncrement;
        img.height += yIncrement;
        if(img.width < maxWidth) {
            setTimeout('callResize()',500)
        }
        alert(document.getElementById('img').width);
    }
   
    function callResize() {
        resize(document.getElementById('img'),1,1,300)
    }
   
    callResize();
</script>

i have an image and i have a _javascript_ object which contains things like
the original size of the image and the size it needs to get to, then I call
this recursive function to increase the size of the image till it reaches it
required size.


so i pass in "obj" being the image object and "params" being the object I
have created.

so each time the function is called it needs to pass in the new data.

I dont want to if possible have to create a bunch of global vars.  I only
want to have what I need outside the functions

It might be a better idea to explain exactly what you're trying to do
rather than posting a small snippet.

 From what I can see you've probably taken the wrong approach, but
suggesting a better one is a bit tricky without a better understanding
of the whole picture.

Hey guys

anyone able to help me with this?

function increaseSize(obj,params)
	{
	//alert(obj.width);
	obj.width = obj.width+10;
	obj.height = obj.height+10;

	if (params.endWidth >= obj.width)
		{setTimeout("increaseSize(" + obj + "," + params +")",1000);}
	}


basically i need to recall the function but keep passing the original
arguments back into the function.

cant seem to get it to trigger

Any ideas?

Regards
Steve
