“后退按钮”

vue

methods: {
    goBack(){
    let state = {
        title: '',
        url: window.location.href
    };
    window.history.pushState(state, state.title, state.url);
    }
},
mounted() {
    if (window.history && window.history.pushState) {
    history.pushState(null, null, document.URL); //这里有没有都无所谓，最好是有以防万一
    window.addEventListener('popstate', this.goBack, false);
    // 回退时执行goback方法
    }
},
// 页面销毁时，取消监听。否则其他vue路由页面也会被监听
destroyed(){
    window.removeEventListener('popstate', this.goBack, false);
}
