javascript – 如何知道Firefox中是否单击了刷新按钮或浏览器后退按钮

如何在Firefox中了解是单击了刷新按钮还是单击了浏览器后退按钮…对于这两个事件onbeforeunload()方法都是回调.对于IE我正在这样处理:
function CallbackFunction(event) {
if (window.event) {
if (window.event.clientX < 40 && window.event.clientY < 0) {
alert("back button is clicked");
}else{
alert("refresh button is clicked");
}
}else{
// want some condition here so that I can differentiate between
// whether refresh button is clicked or back button is clicked.
}
}
<body onbeforeunload="CallbackFunction();">
但在Firefox中,event.clientX和event.clientY始终为0.还有其他方法可以找到它吗?
解决方法:
用于刷新事件
window.onbeforeunload = function(e) {
return 'Dialog text here.';
};
和
$(window).unload(function() {
alert('Handler for .unload() called.');
});
