Warn user on leaving page

Question

I want to warn user before closing page, but only if the page is processing or uploading its data to the server. Its asp.net web application. I have used onbeforeunload javascript event to show the message, but it seems to be not fitting in my scenario.

  $(document).ready(function () { $('.saveButton').click(function () { window.btnClicked = true; }); }); function closeEditorWarning() { if (window.btnClicked) { return 'It looks like you have been uploading something -- if you leave before submitting your changes will be lost.' } } 

Answer 1

Can you put your code for how you are calling closeEditorWarning(). Anyway I tried this on similar lines and it is working -

$(document).ready(function(){
    $("#save").click(function(){ window.btnClicked = true; }
    );
});

window.onbeforeunload = function(e){ 
    if(window.btnClicked)
        return "Are you sure, you want to leave?";
}

Hope it helps.
