Js monitors IE Firefox to close, refresh, roll back, and forward events, js Firefox
<Html>
Js checks whether the rollback button is executedThis is hard to do. Because the browser processing method is different. Chrome and ie will reload the js and restore all the states. The js that should be taken should be reloaded, but firefox will not. That is to say, setting a flag in Firefox makes it easy to judge, but chrome and ie cannot.
Js captures the page closing event. In my opinion, how can I not refresh in IE and trigger the event upon a refresh?If it is not refreshed once, the page will load and execute onBeforeUnload. When you move the mouse, onmouseout = "ClosesWindow = true;
Another reason may be that these event handler functions are not compatible with ie. Try another method.
