利用HTML5 history新特性replaceState方法可以修改当前页面地址栏参数，示例代码：
//选择日期后改变地址栏var urlSearch = location.href;var unformatStr = changeURLArg(urlSearch, "depDate", Qdate);if (!!(window.history && history.pushState)) {history.replaceState(null, "", unformatStr);}function changeURLArg(url, arg, arg_val) {var pattern = arg + ‘=([^&]*)‘;var replaceText = arg + ‘=‘ + arg_val;if (url.match(pattern)) {var tmp = ‘/(‘ + arg + ‘=)([^&]*)/gi‘;tmp = url.replace(eval(tmp), replaceText);return tmp;} else {if (url.match(‘[\?]‘)) {return url + ‘&‘ + replaceText;} else {return url + ‘?‘ + replaceText;}}} 类似的方法还有pushState，具体请参考以下资料。
