为 Ajax 应用程序启用 back/fwd 键事件 [英] Enabling back/fwd key events for an Ajax Application

问题描述

我有一个在 AJAX 上工作的应用程序.但是我想在其中包含导航功能.为了欺骗 url，我正在更改 location.hash，以生成 URL.但是如果我使用 back/fwd，只有 url 改变，但页面不会重新加载.如何覆盖 hstory.back 以重新加载页面.

I have an application which works heavily on AJAX. However I want to have navigation functionalities in it. To spoof the url, I am changing the location.hash, to generate URL. But if I use back/fwd, only the url changes, but page wont reload. How can I override the hstory.back to reload the page.

推荐答案

我不知道除了连续轮询之外还有什么其他方法可以实现这种行为.实现可能如下所示:

I don't know of any other way than continuous polling to implement this behaviour. An implementation might look like this:

var lastHash = '';

function pollHash() {
    if(lastHash !== location.hash) {
        lastHash = location.hash;
        // hash has changed, so do stuff:
        alert(lastHash);
    }
}

setInterval(pollHash, 100);
