Javascrript help

Could someone please tell me how to obtain the Value of the file/browse box on an HTML form using Javascript. (or any form field for that matter.)

Any help appreciated. Whilst my PHP is ok my Javasript is sadly lacking so keep it simple.

Cheers

all you need to do is reference the value of the form field like so.

document.formname.fieldname.value

and assign it to a variable. The following example will show a popup alert of the field value of the input file type when you click the submit button.

<form method="post" name="form1">
<input type="file" enctype="multipart/form-data" name="file" />
<input type="submit" name="submit" value="Submit" onclick="alert(document.form1.file.value);return false;"/>
</form>

note the return false is there to actually prevent the form from being submitted for this example. If you put this code in a page and then browse for a file, then click the submit button, the popup will show the file selected. This method can be used for any form field.
