I have a button that activates a script to create a new radio button. I want the radio button to be of the class draggable. However, my code isn't quite working.

Any thoughts on this are appreciated.

		<script Language="JavaScript">

function modify(){
	var newElem= document.createElement("radio")
	newElem.id = "newradio"
	document.getElementById("emphasis1").childNodes[0].nodeValue = "first "
<button onClick="modify()">Add a radio</button>


Do you mean CSS class? If so setAttribute should work. I've not tested this.

newElem.setAttribute("class", "draggable")

newElem.setAttribute("class", "draggable")

That works (no errors returning)! Thanks.

However, it still doesn't create a radio button on the page. I'm kind of a newbie, and any advice is appreciated.

You have to append it to the DOM once you have created it. It's an input element so I assume you want it in a form? rather than appending to the body element.


You have this ?????


I'm not sure what happens when you append an element to itself.

Also I think document.createElement("radio") should be document.createElement("input") then set it's type to radio newElem.type = "radio"

Thanks! Unfortunately the code

var newElem= document.createElement("input")
	newElem.type = "radio"

Creates a null when the code attempts the append child method:


Hmmm I've had a go myself. This is what I got:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

    <script type="text/javascript">
var radioNum = 1;

function addRadio()
            var radio = document.createElement("input");
            radio.id = "radio" + radioNum; //Gotta love that loosley typed implicit conversion!!!!
            radio.setAttribute("type", "radio");
            radio.setAttribute("name", "radios");
            radio.value = "myvalue";
            //radio.setAttribute("onclick", function(){alert(this.value);});

    <form id="form1" method="POST" action="#">
        <input type="button" id="btnAddRadio" value="Add radio" onclick="addRadio();" />
        <div id="divRadiolist"></div>

It works great in Firefox, but in IE7 when I click a radio button it doesn't stay selected!

Anyone got any ideas?
