onbeforeunload替代Chrome [英] onbeforeunload alternative for Chrome

问题描述

是否有任何替代windows.onbeforeunload for Chrome.It在IE中工作正常但不在chrome中，这是我的代码..





window.onbeforeunload = CloseSession;



函数CloseSession（）{

//如果浏览器关闭则从需求中注销用户如果（（（window.event.clientY< 0）&&（window.event.clientX> 40））

按下或按下alt + f4不用于后退按钮

||（event.altKey == true && event.keyCode == 0））

window.open（'LogOffUser.aspx'，'_ parent'，'left = 9999，top = 9999，width = 1px，height = 1px'）;

}

Is there any alternative for window.onbeforeunload for Chrome.It working fine in IE but not in chrome,here is my code..


window.onbeforeunload = CloseSession;

function CloseSession() {
//log out the user from demand if browser close or alt+f4 is pressed not for backbutton
if (((window.event.clientY < 0) && (window.event.clientX > 40))
||(event.altKey == true && event.keyCode == 0))
window.open('LogOffUser.aspx', '_parent', 'left = 9999, top = 9999,width=1px, height=1px');
}

推荐答案

这是我用来设置onbeforeunload事件的代码，它可以工作对于Chrome。

它写的顺序是至关重要的，否则它不会起作用。

This is the code that I used to set the onbeforeunload event and it works for Chrome.
The order it was written is crucial though else it wouldnt work.

<script>

    var unloadEvent = function (e) {
        var confirmationMessage = "Warning: Leaving this page will result in any unsaved data being lost. Are you sure you wish to continue?";

        (e || window.event).returnValue = confirmationMessage; //Gecko + IE
        return confirmationMessage; //Webkit, Safari, Chrome etc.
    };
    window.addEventListener("beforeunload", unloadEvent);
</script>
