直接引入以下代码就可以实现
XBack = {};
(function(XBack) {
= 'x - back';
;
= function(event) {
=== && ();
(); //初始化事件时，push一下
};
= function(state) {
(state, null, );
};
= function() {
var event = ('Events');
(, false, false);
(event);
};
= function(listener) {
(, listener, false);
};
= function() {
= ('span');
('popstate', );
();
};
})(XBack); // 引入这段js文件
();
(function() {});
