Question

I just learned something interesting. The add method for the javascript select object in IE 6 takes only one parameter. It throws an error when you pass it two parameters which I believe is the standard, even as documented on the MSDN site.

My question is this. What is your best-practice recommendation for programmatically adding option elements to a select element in javascript?

• Call the add method differently based on the value of the user agent?
• Wrap the select object in a class that provides the proper method signature?
• Use a javascript library which does this for you (specify which library)?

You can use a try-catch block for doing this :

              try     {         //Standards compliant         list.add(optionTag, null);     }     catch (err)     {         //IE         list.add(optionTag);     }
