大家好，我在

Hey guys here i am calling

UpdateUserLogoutSession

事件中调用

window.onbeforeunload

...
现在的问题是，它在IE和Chrome上都可以正常工作..但是在Firefox浏览器上却无法工作...
此功能确定页面是已刷新还是已关闭........
因此，我想在刷新事件上使用

event...
Now the problem is this works great on IE and Chrome..but it doesnt work on Firefox browser...
This function identify whether the page is REFRESHED or Closed........
So i want to use

UpdateUserResetSession 

并在关闭时使用

UpdateUserLogoutSession

.
有没有办法在Firefox中做到这一点?
为何不起作用?
还有一件事....如果我放

on close..!

Is there a way to do this in Firefox?
And Why it is not working?
One more thing....if i put

alert("hi");

在

setCookie('session', sessionID, 1);
            var cookieSU = getCookie('session');
            if (cookieSU != null) {
                getSyncData('strSessionId=' + sessionID, 'UpdateUserLogoutSession');
            }

很好用..但是当我尝试时没有警报..它不起作用吗?

有什么问题?

it just works great..but when i try without alert..it doesnt work?

Whats the problem?

推荐答案

(``document'').bind(''keypress''，函数(e){ 如果(e.keyCode == 116){ validNavigation = true; } });

(''document'').bind(''keypress'', function (e) { if (e.keyCode == 116) { validNavigation = true; } });

("a").bind("click"，function(){ validNavigation = true; });

("a").bind("click", function () { validNavigation = true; });

("form").bind("submit"，function(){ validNavigation = true; });

("form").bind("submit", function () { validNavigation = true; });
