Here you can call like this Let this is my Input File control
<input type="file" title="search image" id="file" name="file" onchange="show(this)" />
Now here is my Jquery which get called once you select the file
<script type="text/javascript">
function show(input) {
var fileName = input.files[0].name;
alert('The file "' + fileName + '" has been selected.');
}
</script>
