JS/DOM Question

Mr E

Hi all,

I'm trying to adapt a function that calculates the size of images on a webpage. The function is as follows:

function calculate()
{
	if (!document.fileSize)
	{
		alert('This script does not work in your browser.');
		return;
	}
	var size = (document.fileSize)*1;
	var y = document.images;
	var imglength = 0;
	for (i=0;i<y.length;i++)
	{
		imglength += (y[i].fileSize)*1;
	}
	var total = size + imglength;
	var writestring = 'File size HTML: ' + size;
	writestring += '\nFile size images: ' + imglength;
	writestring += '\nTotal file size: ' + total;
	if (total > 40000) writestring += "\nFile too large!";
	alert(writestring);
}

What I'm trying to do is pass a URL as a parameter instead of just using the current page. I'm not a DOM expert, so I'm not sure if its possible using 'document.whatever'. Any suggestions? Intended usage would be:

calculate('http://www.google.ie/index.html')

Is it possible? Thanks in advance...

Actually in hindsight, I don't think it can be done like this. The page will still need to be physically loaded for this function to work. I'll figure out a different way of doing it. Cheers.....

Javascript use of the DOM as you have figured out is client side only Most server side languages are well able to do this sort of thing - PHP in particular is probably well suited for this exact thing.
