Use server-side application variables to drive client-side scripts

Posted on by

You can use serverside variables to drive client-side javascripts. Server-side variables get processed and the results output by the time the page is rendered, so the value of the variable can be used in client-side functions.

In an ASP application I’m working with, I wanted a different tooltip to show up on each tab, depending on what the tab title was. There is a server-side variable called “tabs[i].title”. So I created a little client-side function to test the value of the title on each tab.

 
<script>
var tabName ;

function whichTab(tabTitle){
   if (tabTitle == 'Summary'){
   tabName = Summary;
}
else if (tabTitle == 'Plan Details'){
   tabName = PlanDetails;
}
else if (tabTitle == 'Certifications'){
   tabName = Certifications;
}
else if (tabTitle == 'Transcript'){
  tabName = Transcript;
}
}
</script>

Switch layers on the next page by clicking a link

When I tried setting the value of a variable on the new page, it worked in some browsers but not others, probably because some computers are slower at loading pages than others, and the necessary layers would not be loaded in time for the variable to have something to populate.
