Accessing File input text.

[Mike]

Hello,
I am trying to access the text in the file input field.
This is not working:


The function:
function post_value(){
opener.document.TestForm.parentform.value =
document.childform.fileinput.value;
self.close();
}

This is the form:
<form action="" method="get" enctype="application/x-www-form-
urlencoded" name="childform">
<input name="fileinput" type="file" />
<input type="submit" name="UploadandClose" id="UploadandClose"
value="UploadandClose" onclick="post_value();" />
</form>

Thanks
Mike

If this is an attempt to upload a file through an AJAX object, it will
fail. There are security reasons that javascript can't upload
arbitrary files on a client's computer.

If you want to upload a file without refreshing the main window, it
needs to be done with a combination of javascript and an iFrame. See:

Neither is "javascript" a necessity in this case, nor is an `iframe'.
An existing `iframe' element can be hidden with CSS, and instead of
an `iframe' element a `frame' element or another window can be used.

I am not concerned with uploading the file.
After I click the browse button and the file name is in the text box,
I want to access the text to pass it to a parent document.
Thanks

On the web you can't do that, it is formally forbidden !

You can only (try) to do it in local.


(*) try : the file given in the attached text-field will not be reached
so easily : there are so many ways to type a file's address ...
(depends of browser, depends of system)

Please adhere to the aforementioned advisory and don't full-quote either.

<form action="" onsubmit="post_value(this); return false">
<script type="text/javascript">
function post_value(o)
{
// see FAQ 4.10
var w;
if ((w = window.opener) && !w.closed)
{
w.document.forms["TestForm"].elements["parentform"].value =
o.elements["fileinput"].value;
}

window.close();
}
</script>

<input type="file" name="fileinput">
<input type="submit" value="Upload">
</form>

If eventually no upload would be involved, I wonder what you would do with
the local file path, though.
