background colour of page

Hi there

I've never been asked this before so hence the posting but I've got a combination of asp vbscript and javascript working to perform a check on a value - if that value exceeds x amount then the prompt appears informing the user that they have added too much.

This is essentially it:

<%

if desiredValue >= 100 then

%>

<script language="javascript">
window.alert("Your total value must not exceed 100.00");
history.back();
</script>

<%

end if

%>

During the time the javascript alert appears the page background turns white - is there a way to make the background colour of the page different during the time the alert is on the screen?

thanks

Adam

Does it turn white? Or is it white all the time?

Your code seems to fire as soon as that part of the HTML is loaded which means the browser may not have enough HTML loaded to display the correct page. You could defer executing that JavaScript until the DOM has finished loading, using jQuery for example.

Hope this helps,

Hi Imar

It turns white, yes, but I think it's down to the DOM not loading the html since it's fired before then.

thanks

Yes, so you can emit some simpe HTML with the required background settings and then run your code when the DOM is ready.
