2,191,749 | I need to focus out from the textbox when it focus in.
I try to set focus for outer div and its working fine in IE but not in mozilla.
How do I do this?
This is my current code:
```
<div id="outer"> <input type = "textbox" /></div> Onfocus: document.getElementById("outer").focus()

] | I wonder what's the purpose of using a textbox in this case if the user can never write anything inside. Just add a `disabled="disabled"` attribute or `readonly="readonly"` (in case you want to post the value). | Where is the point in that? JS would be (didn't test it):
```
$('#textbox').focusin(function() {
$(this).focusout();
});

In JS:
```
document.getElementById("input1").onfocus = function () { this.blur(); }

Some elements cannot accept focus without being editable. | Where is the point in that? JS would be (didn't test it):

$('#textbox').focusin(function() {
