确认导航不工作

Confirm navigation not working

本文关键字：工作 导航 确认      更新时间：2023-09-26

我看到过这个用法，但它对我不起作用

 var needToConfirm = true;
window.onbeforeunload = confirmExit;
function confirmExit() {
    if (needToConfirm)
        return "You have attempted to leave this page.  If you have made any changes to the fields without clicking the Save button, your changes will be lost.  Are you sure you want to exit this page?";
}

我能够使用jQuery的在IE和FF中工作

$(window).bind('beforeunload', function(){
});
