<script type="text/javascript">

function preview(test){
    var source=test.value;
    alert(source);
}
</script>

but in the alert message, i am getting only

Filename.extension

I am not getting full path, but it is showing full path in File Upload box please help how to solve this problem

This is a browser security restriction, in modern browsers you cannot get the full client file-system path of the selected file, nor set a path programmatically...

Maybe for security reason, javascript doesn't allow this to happen. And if you come to think of it, Server side pages cannot access your local files. Not that I have a solution for your question.
