Menu
I have created a form in a iframe (using Walter Zorn’s wz_tooltip.js) and I want to use javascript to validate the contents before posting. I’m not sure what parameter in the DOM to use to retrieve the data. When not in an iframe I can use (document.testit1.form1.value) and data is returned properly. When I attempt this (document.testit2.form2.value) when the form is in an iframe I receive the error
document.testit2.form2 is undefined
document.write(document.testit2.form2.value);
The link for the sample code is [url]http://www.schuckman.com/misc/testform/testform.html
Follows is sample code to demonstrate the problem
Any help will be appreciated.
