Window.onbeforeunload fires in IE for partial postback events

I want to warn users when updating or clicking a browser button if they have entered something in the text fields. So I used the window.onbeforeunload function to do this.

window.onbeforeunload = function () {
    if (if user hasn't entered any thing) {
        return;
    }
    return 'Entered data will be lost.';
};

this javascript code works fine in Firefox and Chrome. But in IE, this function works for buttons with partial feedback. Any solution to solve this problem in IE? Thank:)

  • This is due to an error in IE.

window.onbeforeunload IE . " ". href= "javascript:...." (ASP.Net LinkButton ), IE . dirtyflag

var __ignoreDirtyFlag = false;

$(document).ready(function () {
    if ($.browser.msie) {
        $('[href^="javascript:"]').bind('click.ignoreDirtyFlag', function () {
            __ignoreDirtyFlag = true;
        });
    }
});

, , , href ^ = "javascript:", . , __ingoreDirtyFlag ;

window.onbeforeunload = function globalWindowUnload() {
    if (!__ignoreDirtyFlag && isDataFilled == true) {
        return "You have unsaved changes on this page. If you leave this page, those changes will be lost.";
    }
    __ignoreDirtyFlag = false;
    return;
};

The goal is to log out every time you close your browser or manually change the recipient's URL

var url_auth = '';var __ignoreDirtyFlag = false;$(document).ready(function () {if ($.browser.msie) {$('a').live('click', function () { __ignoreDirtyFlag = true;}); $('*').bind('submit', function () { __ignoreDirtyFlag = true; });window.onbeforeunload = function () {if (!__ignoreDirtyFlag) {if (window.location.href.indexOf("DEV2") != -1) {$.post("/DEV2/SSQ/AUTH/LOGOUT", null);return 'Tem certeza que deseja encerrar a sessão ?';}}};
