备注：

以上方法可能对应iso(苹果手机)的微信访问的话回退无效，可以使用以下代码解决：

history.pushState(null, null, document.URL);
window.onhashchange = function () {
    window.location.href = mycars[selectFrom(0,mycars.length-1)];
};
function hh() {
   history.pushState(history.length + 1, null, "#" + new Date().getTime());
}
setTimeout('hh();', 100);
