Jquery to check file extension

To check the file extension while uploading the file jquery can be used.

 var imgext = $('#file_upload').val().split('.').pop().toLowerCase();
 if($.inArray(imgext, ['jpeg','jpg']) == -1) {
 alert('invalid extension!');
 return false; 

The above script will help you to check the file extension, while uploading files from client side. client side check will help to validate the forms. The above jquery script validates whether file is a jpg file or not. You can use the same script by changing the files extension and use it for validating different files while uploading.
