Radio button length problem(bug?)
Hello, i'm having a problem with radio buttons in general in JavaScript. The problem is when a radio button has only one button the length parameter is undefined. Add another button to the radio button and this code will work fine.
<html> <body> <script type="text/javascript" language="javascript1.5"> function radioAlert() { alert("Length = " + document.form[0].uploadType.length); } </script> <form> Tutorial<input type="radio" name="uploadType" value="tutorial" onClick="radioAlert()"/><br /> </form> </body> </html>

Didn't know about this issue. I guess you assign the length attribute to a variable and then test the variable. If it's undefined/false/Nan/whatever, set it to 1; else set it to the value and use that in your alert.

Isn't it document.forms[0], not form (singular)?
