如何知道刷新按钮或浏览器的后退按钮是否被点击在Firefox [英] How to know whether refresh button or browser back button is clicked in firefox
问题描述
如何在Firefox知道刷新按钮是否被点击或浏览器后退按钮被点击...这两个事件的 onbeforeunload（）方式是一个回调。对于IE我正在处理这样的：
How to know in firefox whether refresh button is clicked or browser back button is clicked... for both events onbeforeunload() method is a callback. For IE i am handling like this:
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中的 event.clientX 和 event.clientY 总是为0是否有任何其他的方式来找到它？
But in Firefox event.clientX and event.clientY are always 0. Is there any other way to find it?
推荐答案
在刷新事件使用的
window.onbeforeunload = function(e) {
return 'Dialog text here.';
};
<一个href=\"https://developer.mozilla.org/en-US/docs/Web/API/window.onbeforeunload?redirectlocale=en-US&redirectslug=DOM%2Fwindow.onbeforeunload\">https://developer.mozilla.org/en-US/docs/Web/API/window.onbeforeunload?redirectlocale=en-US&redirectslug=DOM%2Fwindow.onbeforeunload
和
$(window).unload(function() {
alert('Handler for .unload() called.');
});
