I am currently making a wysiwyg editor for an application, and trying to keep it as unobtrusive as I can.

the type of code I keep running into (which does work) looks like.

 
//set to always drop content into input box onsubmit;
		document.getElementById('wysiwyg_input:'+i).form.onsubmit = (
			function(i,old_onsubmit) {
				return function(){
					if(document.getElementById('wysiwyg_input:'+i))
						document.getElementById('wysiwyg_input:'+i).value = document.getElementById('wysiwyg_editor:'+i).innerHTML;
					if(old_onsubmit) old_onsubmit();
				}
			}
		)(i,document.getElementById('wysiwyg_input:'+i).form.onsubmit);

Open in new window


this code takes the value of the wysiwyg_editor and puts it into the wyswyg_input to be sumbitted by a form.  The i value is saying which wysiwyg_editor on the page it is because i loop through every one and assign this when they are created.

This code just is hard for me follow and although it does work i am looking for a better way of doing it.

I think you are looking for attachEvent
 However the code you have is ok and works so why mess with the two versions of attaching events you need, one for IE<9 and one for the rest?

looking into it, its not perfect but i like the attachEvent way better.

it makes it easier to put it in an outside function and clean up the main script.

Thank you for pointing me in the right directions
