监听路由跳转

最近要写一个前端统计的项目，需要监听页面跳转

 private captureRouteChange() {
    if (this.option.useHash) {
        window.addEventListener('hashchange', (e) => {
            this.changeURL({
                currURL: e.newURL,
                oldURL: e.oldURL
            });
        }, false);
    } else {
        ((history) => {
            // 覆盖 history.pushState 方法
            const pushState = history.pushState;
            history.pushState = (...args) => {
                let oldURL = window.location.href;
                const res = pushState.apply(history, args);
                this.changeURL({
                    currURL: window.location.href,
                    oldURL
                });
                return res;
            };
            const back = history.back;

            let oldURL = window.location.href;
            history.back = (...args) => {
                oldURL = window.location.href;
                const res = back.apply(history, args);
            };
            window.addEventListener('popstate', (event) => {
                this.changeURL({
                    currURL: window.location.href,
                    oldURL
                });
                oldURL = window.location.href;
            });
        })(window.history);

    }
}
