Hide/Unhide div using Radio button onClick

Hide/Unhide div using Radio button onClick

I've been trying this for days. JavaScript isn't even firing. Any Suggestions?? I'm using it with Coldfusion.

<script language="JavaScript" type="text/javascript">
function hide(divToHide) {
var me = document.getElementByID(divToHide);
if (me.style.display == "none"){
me.style.display = "block";
} else {
me.style.display = "none";

<div class = "col-md-12">
<label class="radio-inline">
<input type="radio" value=1 name="decision" class="grey" onClick="hide('hideThis');">
<span style="color:red">Reject</span></label>
<label class="radio-inline">
<input type="radio" value=2 name="decision" class="grey" onClick="hide('hideThis');">
<span style="color:green">Approve</span></label>

<div id="hideThis" style="display:none;">
<button class = "btn btn-blue btn-block" type = "submitAssign" name ="submitAssign" id = "submitAssign">
Assign <i class = "fa fa-arrow-circle-right" ></i>

RE: Hide/Unhide div using Radio button onClick

Javascript is case sensitive. getElementById is different to getElementByID.

This should have popped up an error in the Js console of whatever browser you are using. Something like: Uncaught TypeError: document.getElementByID is not a function

Still not working. No errors! Works in the Tryit Editor on the w3schools website. Just can't get it to work in my ColdFusion page.

should be hide(this.id)

RE: Hide/Unhide div using Radio button onClick

I found the issue after some removing and added back sections and pieces of code around the Radio buttons. The culprit was the class="grey" in <input type="radio" value=1 name="decision" class="grey" onClick="hide('hideThis');"> It was the onClick event that wasn't working because of that piece of code, the JavaScript was working fine. Works like a charm now.

Thanks to all anyway for the responses.
