[jQuery] Re: Simple question about Radio Buttons
Well I fixed it, I had to use: $(this).attr(checked) to get the value. Should I have known this?

Am I doing something wrong? here are two of the radios: input name=recvd_loan type=radio value=1 / Yes input name=recvd_loan type=radio value=0 / No Thanks!

You could use either this.checked or $(this).attr(checked). this refers to the dom node, so if you want to use the attr method on this you have to jQuery-ize it. this.checked would be more performant, since you are not executing the jQuery function in that case. -- Josh - Original Message - From: Namlet [EMAIL PROTECTED] To: jQuery (English) jquery-en@googlegroups.com Sent: Friday, September 19, 2008 1:11 PM Subject: [jQuery] Re: Simple question about Radio Buttons Well I fixed it, I had to use: $(this).attr(checked) to get the value.
