I have a simple question that I can't seem to find an answer to any where else:
What do I need to do to find out which radio button is "checked," for the purpose of writing a cookie depending on which option is selected. I've tried to do it as I would a checkbox, but can't get it or any variations to work. Any help would be most appreciated. Thank you! HyperWhiz aka Tyler

It'd be easier to help if you provide a code sample, but here goes:
First off, I checked the Javascript reference at http://developer.netscape.com and it appears that radio buttons have a "checked" property just like checkboxes do, but in an array, one per button. A code example: <script language="JavaScript"> <!-- function test() { for (i=0; i<document.myForm.myRadio.length; i++) { if (document.myForm.myRadio[i].checked) { alert(document.myForm.myRadio[i].value); } } } // --> </script> </head> <body> <form name="myForm"> <input type="radio" name="myRadio" value="first"><br> <input type="radio" name="myRadio" value="second"> <p> <input type="button" value="test" onClick="test()"> </form> </body> Hope this helps, Ton [This message has been edited by tvanbart (edited October 08, 2000).]
