vuejs用mounted创建监听事件，用destroyed销毁监听

mounted() {
	//d创建监听
    window.addEventListener("popstate", this.listenerPopstate, true);
},
destroyed() {
	//销毁监听
	window.removeEventListener("popstate", this.listenerPopstate, true);
},
methods: {
	//监听方法
	listenerPopstate() {
      ZWJSBridge.close();
    }
}
