I want to change URL without without reloading the page. The possible solution I found is
我想在不重新加载页面的情况下更改 URL。我发现的可能解决方案是

window.history.pushState('page2', 'Title', '/page2.php');
but some browser like Firefox 3.5, IE6+ does not support this, so for them solution is
但是一些浏览器如 Firefox 3.5, IE6+ 不支持这个，所以对他们的解决方案是
var uri = window.location.href;

if (history.pushState) {
// supported.
}
Quickest test is to run this in the browser console to see if it's supported:
最快的测试是在浏览器控制台中运行它以查看它是否受支持：
if (history.pushState) { alert('supported'); }
Also notice that in FF typeof(history.pushState)returns "function", while in IE it returns "undefined"
另请注意，在 FF 中typeof(history.pushState)返回“函数”，而在 IE 中返回“未定义”
