<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.0/jquery.min.js"></script>
<script>
$('#purpose').on('change', function () {
if (this.value === "1") {
$("#business").show();
$("#local").hide();
} else if (this.value === "2") {
$("#business").hide();
$("#local").show();
} else {
$("#business").hide();
$("#local").hide();
}
});

</body>
</html>the above code works fine if i run it in fiddle, but not when i run it on my local computer, can someone help me, what should i do for the above problem, any kind of help i thank you.
The <select id='purpose'> doesn't exist yet when you try to run $('#purpose').on('change', ...). Either move your <script> tag to the end of the <body> tag, or add a defer attribute to the tag (which follows best practices anyways).
Try this, you just needed to move few things around.
$('#purpose').on('change', function() {
if (this.value === "1") {
$("#business").show();
$("#local").hide();
} else if (this.value === "2") {
$("#business").hide();
$("#local").show();
} else {
$("#business").hide();
$("#local").hide();
}
