Question

Using javascript, how do I add some data to the query string?

Basically I want to add the window.screen.height and window.screen.width info to the query string so that I can then email it with the other login info.

Alternatively, how would I populate a couple of hidden fields with the same data, a form is being submitted so I could pick it up from there?

Thanks, R.

I think that the latter option would be easier to implement. For example, if you have the hidden fields like this:

...
<input type="hidden" name="screenheight" id="screenheight" value="" />
<input type="hidden" name="screenwidth" id="screenwidth" value="" />
...

Then the JavaScript would be:

<script type="text/javascript">
document.getElementById('screenheight').value = window.screen.height;
document.getElementById('screenwidth').value = window.screen.width;
</script>
