An Attempt at Dynamic Content via Javascript

11/21/2005 12:48 PM by Chris Toohey

It's a simple enough chore really - dynamic DHTML based on QueryString parameters, and run by Javascript (non-Domino backend, wouldn't ya know!). It's turning into a ranting hate for Internet Explorer possibly fueled by a hiccup in my code or a lack of knowing about some security lockdown that was released at 3:27AM last night from Redmond! Here' the gist - see if you can figure it out!

Without much further ado - this is what I'm doing:

Using the QueryString parser found here, I call a function that's designed to check the current QueryString for the key that I pass, see if it has a value, and see if that value has a correlating "function" (via a switch function) all to set the innerHTML of a given element. Because I wouldn't know what the heck someone was talking about from reading that last line, here's a live example showing what I'm trying to accomplish:

Now, if you open that link, you'll get an alert (at least at the time of this publishing) telling you that there's no function trigger... because there's not. Using the QueryString ?Open&val=something would return either the correlating function, or a prompt letting you know that your function, while it was defined, wasn't found in the list.

Now, I've got this thing working wonderfully in Mozilla and Opera, but I get a nasty runtime error in Internet Exploder Explorer.

Can you see what I don't?!

Update

Something should be said for giving your brain a day's break from any issue! While I was posting a reply to Vince, I happen to look at the markup for my example again. As I wanted to reference the ID of the <div>-tag that I used, I found that I had actually used a <p>-tag, which wouldn't handle a now-nested paragraph via the innerHTML method. After changing the <p> to a <div>, it began working as designed!
