使用AJAX返回按钮和刷新

Question

I need a solution for the page refresh and the back button when using AJAX.

I'm using simple javascript for the AJAX implementation.

If anybody could send a code snippet I would be very grateful.

Answer 1

如果你正在使用jQuery，那就是历史插件 。

Answer 2

Here's a solution that I've used in some of my pages. Add this to pages that changes are made at.

window.onbeforeunload = function() {
     window.name = "reloader"; 
}

this triggers when you leave those pages. You can also trigger it if there were changes made. So that it won't unnecessarily reload the page that needs reloading. Then on pages that you want to get reloaded on after a the browser "back" use.

if (window.name == "reloader") {
    window.name = "no";
    location.reload();
}

this will trigger a reload on the page you need reloading to.

Answer 4

essentially, you need to use & monitor the hash portion of the url...

http://.../path?parms#hashpart

Whan you change the hash, iirc window.location.hash , it won't reload the page, but your ajax can monitor, and respond to it.

Answer 5

尝试PathJS它不需要jQuery或任何其他额外的lib。

Answer 6

The onbeforeunload event can be useful to guard against refreshing but it fires if you navigate away or refresh. If you require that users login to the app you can always show a generic message advising against navigating away and refreshing. If users click your app log out button set a var to disable the warning. Could probably also make a 'Close' button that does the same thing.
