View Full Version : Dynamic input form field elements, works IE not FF

07-20-2007, 12:34 PM
I've been looking for a javascript like this example: http://javascript.internet.com/forms/dynamic-input.html

Here you can fill in (in this example) a number of URLS, then this script adds a number of fields on the HTML page.

The example works from internet.com in internet-explorer but not in firefox.

Does anybody has experience to create this javascript cross-browser compatible? Or does anybody has maby another examples by getting these functions.

Thanks in advance!
