短jquery退出弹出脚本需要以某种方式修改

Question

下面是我在互联网上找到的退出弹出窗口的脚本。

此脚本完美无缺。它会在退出弹出窗口显示时使用Leave / Stay on page按钮同时更改页面。

但是 - 我希望连续两次工作，例如，你在index.php上。

你按退出并且当前页面AJAX加载并覆盖page_exit.php（技术上仍然在index.php上）

用户决定留在页面上并阅读新的重叠div。

尝试再次关闭页面后，但这次使用page_exit_2.php重新加载div。

目前它将继续尝试加载page_exit.php，我不确定如何告诉它在第一次尝试退出后加载page_exit_2.php。

谢谢。

var ExitPopURL = 'page_exit.php'; //This is the URL where your 'exit page' is located.

var AlertBox = "*****************************************************\n\nWait! Stop! Don't Go!\n\nBefore leaving, we have a special offer for you\n\nClick Sty On Page Now\n\n*****************************************************"; // This is what the alert() pop up verbage says.


window.onload = function(){
    // this is where we start our journey...
    createExitPop();
}// end function onunload

function getChildren(n, skipMe){
    var r = [];
    var elem = null;
    for ( ; n; n = n.nextSibling ) 
       if ( n.nodeType == 1 && n != skipMe)
          r.push( n );        
    return r;
};

    return getChildren(n.parentNode.firstChild, n);
