Question

I have a few radiobuttons in a jsp page. I run a javascript method once the page is loaded that seeks for certain radio buttons and change its name so they work like a radio group.

I’m doing it this way because the radio buttons are inside jsf table and I have no access to the name property when coding and I want all of the radio buttons work like a radio group.

Anyways the script run without problems and the radio buttons’ names are changed properly.

But while this works in FF 3 (the work like a radio group) it doesn’t work in IE 6 or IE7 though they have the same ‘name’ property. Does anyone know how can I solve this?

function setRadioGroup (nombreRadio){     var listaRadios = document.getElementsByTagName('input');     var tam = listaRadios.length;     for (i = 0; i < tam; i++){         if (listaRadios[i].type == 'radio' && listaRadios[i].title == 'Seleccionar'){         listaRadios[i].name = nombreRadio;        }     } } 

EDIT: Added the code output of the webpage:

Answer 1

I finally got the answer!

The solution come from this blog, but with some modification (the blog, as many others, solve the problem for create a new element, not to modify an existant one).

The problem is that Internet Explorer does not allow some attributes modification during the run time. One of these is the attribute name. As it can not be modified, the behaviour is not what you’re expecting. The solution is to create a new element, remove the old one and replace it by the new one.

Here the solution (work with Firefox 3 and IE 7):

<script> function setRadioGroup (name){   var listaRadios = document.getElementsByTagName('input');   var tam = listaRadios.length;   for (i = 0; i < tam; i++){     cur = listaRadios[i];     if (cur.type == 'radio' ){       try {       // if not IE, raise an error and go to catch.                       element = document.createElement('<input onclick='alert(this.name + this.value);' type='radio' name='' + name + '' value='' + cur.value + ''>');           parentNode = cur.parentNode;           parentNode.insertBefore(element, cur);           parentNode.removeChild(cur);         } catch (err ) {           cur.setAttribute('name', name);           cur.setAttribute('onclick', 'alert(this.name + this.value);');         }      }   } } </script>  <html>   <head>     <title>My Page</title>   </head>   <body onload='setRadioGroup('test')'>     <form name='myform' action='http://www.mydomain.com/myformhandler.cgi' method='POST'>       <div align='center'><br>         <input type='radio' value='Milk'> Milk<br>         <input type='radio' value='Butter' > Butter<br>         <input type='radio' value='Cheese'> Cheese         <hr>         <input type='radio' value='Water'> Water<br>         <input type='radio' value='Beer'> Beer<br>         <input type='radio' value='Wine' > Wine<br>       </div>     </form>   </body> </html>
