推荐答案

简短的回答是使用URI的#hash部分，这部分如果更新不刷新页面，并且在大多数浏览器，使历史的检验点然而在大多数浏览器说，这意味着在IE6不支持，我认为IE7。 另一种方法是，当你发现IE浏览器，你可以嵌入1个像素的iframe，并设置它的源页面上您的域，使你的JavaScript将它的？该URL的一部分，所以页面刷新，而在这种情况下，IE浏览器将保存历​​史点。 这个问题解决了IE8

The short answer would be use the #hash part of the uri, this part if updated doesn't refresh the page, and in most browsers makes a history checkpoint, however by saying in most browsers, means that no support in IE6, and I think IE7. The other way is when you detect IE, you can embed a 1 pixel iframe and set it's source to a page on your domain, and make your javascript sets its ? part of the url so the page refreshes, and in this case IE will save history point. This problem is solved in IE8
