在使用window.onbeforeunload时捕获用户响应 [英] Capture user response when using window.onbeforeunload
本文介绍了在使用window.onbeforeunload时捕获用户响应的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
如果用户离开页面,我只需要做一些事情。
解决方案
这是我正在使用的解决方案,只有当用户从页面导航时,我才需要做某些事情(如清除会话)。
我有2个全局变量
var clearSession = true;
var confirmExit = true;
window.onbeforeunload = function(){return confirmExit(); }
window.onunload = function(){return clearSession(); }
函数confirmExit(){
if(needToConfirm == true){
返回退出页面;
}
}
函数clearSession(){
if(clearSession == true){
alert(杀死服务器上的会话!!!);
PageMethods.ClearSession();
}
}
然后当然,在每一页上提交/按钮/下拉列表等...您需要确保上述全局变量设置为false。
希望这有助于某人。
Is there a way to capture whether the user clicked OK or CANCEL?
I need to do something ONLY if the user is leaving the page....
解决方案
Here is the solution I am using in a situation where I need to do something (such as clear the session) ONLY when the user navigates from the page.
I have 2 global vars
var clearSession = true;
var confirmExit = true;
window.onbeforeunload = function() { return confirmExit(); }
window.onunload = function() { return clearSession(); }
function confirmExit() {
if (needToConfirm == true) {
return "exit page?";
}
}
function clearSession() {
if (clearSession == true) {
alert("Killing the session on the server!!!");
PageMethods.ClearSession();
}
}
Then of course, on every page submit/button/drop down list etc...you need to make sure that the above global variables are set to false.
Hope this helps someone.
