We can read the selected option of a drop down list box by using onChange event trigger. The onChange event will trigger one JavaScript function and we will try to read the selected item by using getElementById
Here is the code
<html>
<head>
<title>Demo Project on JavaScript listbox onChange</title>
</head>
<script type="text/javascript">
function show_date(){
document.getElementById("msg3").innerHTML= document.getElementById("s1").value;
return true;
}
</script>
