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

I am dynamically creating elements and want to set onblur to do something, this works in FF but not IE,

input.setAttribute("onblur", "myFunction(this)")

So basically the node will look something like this in the end:

<input type="text" onblur="myFunction(this)">

Is there an easy fix?

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)

Yep, I think this is the closest you can get:

input.onblur = myFunction;

What is it you are trying to achieve with this scripting? I think a different approach is needed.

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]();
}

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
