Question

I need to control the page behavior when user click on IE refresh button or from right click -> refresh. Is it possible to detect these action , if yes How?

Answer 1

您可以在重新加载之前执行操作-OnBeforeUnload（）。

Answer 2

 window.onbeforeunload = function (e) {
e = e || window.event;
// For IE and Firefox prior to version 4
if (e) {
    e.returnValue = 'Are you sure? You will lose unsaved changes.';
}
// For Safari
return 'Are you sure? You will lose unsaved changes.';
};

here is the snippet which checks the reload functionality on a page.
