Display one div if nothing is selected
- by Levani
I use this javascript to display different div classes upon selection. I need to display one div class if nothing is selected, for example when page is loaded, and that replace it with one of the divs according to the selection...
<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;
}
}
//-->
</script>
css:
<style type="text/css" media="screen"><!--
.hiddenDiv {
display: none;
}
.visibleDiv {
display: block;
border: 1px grey solid;
}
--></style>
HTML:
<form id="FormName" action="blah.php" method="get" name="FormName">
<select name="selectName" size="1" onChange="showDiv(this.value);">
<option value="">Choose One...</option>
<option value="one">first</option>
<option value="two">second</option>
<option value="three">third</option>
</select>
</form>
<p id="one" class="hiddenDiv">This is paragraph 1.</p>
<p id="two" class="hiddenDiv">This is paragraph 2.</p>
<p id="three" class="hiddenDiv">This is paragraph 3.</p>
Can anyone please help?
