Screen width capture in v7

Question

I know this concept / script Justin Luster kindly provided works in v9 ...

1) Create a Free Format question named "screen".
2) Create a variable named "width" and make sure it is of type "hidden" and also set to "whole number".
3) Enter this HTML for the question:

 <input name="screen_width" id="screen_width" type="hidden" value="">

 <script>
     $(document).ready(function()
     {
         $("#screen_width").val($(window).width());
     });
 </script>

I was testing in v7 and when testing, the free format variable is blank.

Do you have a solution to have it working in v7?

Answer 1

Try this jQuery-less code:

<script>
document.getElementById('screen_width').value = document.documentElement.clientWidth;
</script>

Thanks Zachary. I will give it a test drive in the morning. After 3am Saturday in Australia. Still at it! Busy week.

Hi Zachary, I got the same result when testing your script in v7.

I inserted your script into the free format question and when testing, the screen_width variable was blank?

I can send the ssi file to you. Is there something I've missed?

As mentioned earlier, I had Justin's working nicely in v9.

When using Justin's and your script in v7, the screen_width variable was always blank.
