View Full Version : Help customising this script

10-16-2008, 08:34 AM
Hey guys

This is so noob it isnt funny. But obviously I know absolutley nothing about JavaScript!

I was googling and found this code on the net. Did the job fine... but I need it so that onload, it shows 'this is paragraph 1' rather then nothing under the drop down box.

Also... I feel like there is junk on there that isn't needed to do something like this... If someone knows a better one I can use please tell me!

But the main issue is that it loads showing div id="one"... If you can show me a better way of doing this then that is a bonus!

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN">


<meta http-equiv="content-type" content="text/html;charset=iso-8859-1">
<title>Untitled Page</title>
<script type="text/javascript"><!--

var lastDiv = "";
function showDiv(divName) {
// hide last div
if (lastDiv) {
document.getElementById(lastDiv).className = "hiddenDiv";
//if value of the box is not nothing and an object with that name exists, then change the class
if (divName && document.getElementById(divName)) {
document.getElementById(divName).className = "visibleDiv";
lastDiv = divName;

<style type="text/css" media="screen"><!--
.hiddenDiv {
display: none;
.visibleDiv {
display: block;
border: 1px grey solid;


<body bgcolor="#ffffff">
<form id="FormName" action="blah.php" method="get" name="FormName">
<select name="selectName" size="1" onchange="showDiv(this.value);">
<option selected value="one">first</option>
<option value="two">second</option>

<div id="one" class="hiddenDiv">This is paragraph 1.</div>
<div id="two" class="hiddenDiv">This is paragraph 2.</div>


Cheers for your time guys/girls :)

<body bgcolor="#ffffff" onload="showDiv('one')" >

hm lol, I failed...

I tried putting it into the body onload but I left it as this.value ...

Shows I am an all time low for javascript basics!

Just curious - is it possible to do this without using the body tag?

For example, in the javascript code itself?

Hm I'm sure this is easy to do though!

Though this is irrelevant to your problem, bgcolor is a deprecated attribute (http://www.codehelp.co.uk/html/deprecated.html).

Hope that helps.
