Hi,

How to detect browser window or tab close event or a redirection on client side.

My requirement is, in my project while submitting a form I am uploading files asynchronously and i dont want user to close the tab or move to the different page until the uplaoding is done. I simply want to show a popup to user to wait until all files are uploaded.

How to achive this using javascript or jQuery??

Kind Regards,
Jay

You can use the onbeforeunload event like this.

window.onbeforeunload = function (e) {

        e = e || window.event;



        // For IE and Firefox prior to version 4 

        if (e) {

            e.returnValue = 'Your Pop up Message Goes here';

        }



        // For Safari 

        return 'Your Pop up Message Goes here.;

    };
