Looks like javascript to me? And it sounds like something you would need javascript for anyway. PHP cannot do this alone, so if you don't want to use javascript you will need AJAX. A moderator should move this to the javascript forum soon.

What has this got to do with PHP??

I'll move this to the JavaScript forum.

Show the HTML code. Do you get any errors?

Hello friends..... is it possible to enable radio button in the "onchange" function of an dropdown list using java script in php.

function tlkdisp(Object)
{
var index=Object.ta k.selectedIndex ;
var value=Object.ta k.options[index].value;
document.form1. radiobutton[0].disabled=false ;
document.form1. radiobutton[1].disabled=false ;
document.form1. action="Vresurv ey.php?tak="+va lue;
document.form1. submit();

return false;
}

<select name="tak" class="style21" style="font-family:MLB-TTRevathi" onChange="tlkdi sp(document.for m1)"

this is my code... but i am not able to enable the radio button, it just blinks when i select the dropdownlist..

thanks.

This has nothing to do with php.

I'd recommend looking for an AJAX solution to this - shouldn't be terribly difficult!

Pointless using ajax when there's a pure (and incredibly basic) javascript solution. Using ajax would take up unecessary server resources.

Ask in the JS forum
