I have a form that allows a user to upload a file. When they select a
file (onChange), I call a JS function that analyzes the filename for
specific keywords and then populates a multiple select box with the
keywords.
The problem is, IE for Mac doesn't do the onChange properly. In all
other browsers, as soon as I select the file, the onChange fires and
the filename gets analyzed, etc. In IE for Mac, I have to click away
from the file input box for the onChange to take effect. The user won't
know to do this.
I've tried a ton of things already, including setting timers that force
the file input to lose focus. Nothing seems to work.
Here's a link to the page: http://web.cfa.arizona.edu/memoria/tools/upload.php
Anyone have any ideas?
Thanks.

onchange is supposed to fire when the control loses focus, so in fact
IE Mac is doing it by the book.
"The onchange event occurs when a control loses the input focus and
its value has been modified since gaining focus. This attribute
applies to the following elements: INPUT ,SELECT , and TEXTAREA ."
<URL:http://www.w3.org/TR/html4/interact/scripts.html#ad ef-onchange>
What's the fix? Change your UI so that users know to click away from
the input, say with an 'analyse file path' button or such. Or just
expect that some users will not have their path analysed - those
without JavaScript won't either.

Rob,
Thanks for the response. I think the other browsers are doing it
according to spec also. The difference is that they blur the file input
field automatically, which is nice. There's no reason not to. I feel
like IE/Mac is being lazy.
I'll consider the exta button. I was hoping I wouldn't have to do that.
It's a pretty streamlined process when it auto-analyzes.
Thanks again.

I'm trying to validate some HTML form elements when the
user tabs out of each element. However, I'm having some
problems.
It appears that the order of events is onChange followed
some time afterwards by onBlur. I believe this to be the
case because in my onChange script, if the validation fails,
I force focus back to the field element. However, the focus
still falls to the next field and not back to the field I tried to

Hi there
I'm adding form fields on the fly with some javascript DOM programming.
I basically just clone a hidden <div>, then adjust node properties to
make this new <div> have unique values (style, size, etc.)
the original code of the input tag is:
<input type="file" onchange="alert('original')" size="30" id="filea"
name="filea">

I'm trying to handle the onChange event in an <input type="file">
element. In IE, there's no problem: the event fires when a file in the

value of the element.
But in Netscape 7, onChange doesn't fire until focus leaves the
element. When you double-click a file name or click "open" in the Open
