I’ve come across it so many times, and each time I forget. So in addition to a tidbit, this is also a note to myself.
How many times has it happened that you’ve been programming, working with Firefox, Chrome or Safari and everything works fine until… you open up Â your page in Internet Explorer and you see that awful “unknown runtime error” .
First thing to check if you’re using ajax and trying to set innerHtml is that there are no html syntax errors.
But it can also happen without any ajax, and 9 times out of 10 it turns out the script that’s giving the error needs a delay. You can easily find out by putting an alert() somewhere at the beginning of the script. If it then works, it means you need a delay, which you can obtain using the setTimeout() function.
Here’s a link with information on that function:Â http://www.w3schools.com/js/js_timing.asp
