Why Doesn't input.setAttribute("onblur", "myFunction(this)") Work in IE?

You have to use input.onblur unfortunately

IE interprets what you have as input[onblur] = "myFunction(this)" with the JS as a string.

That doesn't work using

input.onblur = "myFunction(this)"

This is going to be annoying then to try and get the "this" to perform properly. I may have to change the code to use a cloneNode(true)

I didn't suggest addEventListener because it is not well supported but forgot I tackled this same issue earlier. If you are interested, here is the cross browser compatible function I use. It invokes addEventListener, attachEvent or a pseudo method I conjured up that I use for this sort of stuff. Should work in your case.

e.g.
addEvent('input', 'blur', 'myFunction');

function myFunction(evt) {
// ...

Also see:
http://www.captain.at/howto-addeventlistener-attachevent-parameters.php

function addEvent(ele, event, callback) {
  if (typeof(ele) == "string")
    ele = byId(ele);
  if (ele.addEventListener) {
    ele.addEventListener(event, callback, false);
  } else if (ele.attachEvent) {
    ele.attachEvent("on"+event, callback);
  } else {
    psuedoAttachEvent(ele, event, callback);
  ele["on"+event] = function() { psuedoTriggerEvents(ele, event) };
  }
}
 
function psuedoAttachEvent(ele, event, callback) {
  if (!ele.psuedoEvents) ele.psuedoEvents = {};
  if (!ele.psuedoEvents[event]) ele.psuedoEvents[event] = [];
  ele.psuedoEvents[event][ele.psuedoEvents[event].length] = callback;
}
 
function psuedoTriggerEvents(ele, event){
  if (ele && ele.psuedoEvents && ele.psuedoEvents[event])
    for (var i=0, len=ele.psuedoEvents[event].length; i<len; i++)
      ele.psuedoEvents[event][i]();
}

Select allOpen in new window

thanks a lot. Actually what I did was had a dummy template node with the onblur already in there and set it to display:none

and then I clone it and change the id to make it unique.

Thanks for your help
