不支持canvas

vue+cordova实现退出app效果

//vue钩子函数created方法中添加监听等待设备API库加载好
created(){
  var that = this;
  document.addEventListener("deviceready", that.onDeviceReady, false);
}
methods:{
    //设备API可以使用了,然后在vue的methods中添加如下方法
  onDeviceReady() {
    var that = this;
       document.addEventListener("backbutton", that.eventBackButton, false);
  },
  //监听返回键按钮事件
  eventBackButton(){
    var that = this;
       that.$toast('再按一次退出');//这里使用的是vantUI框架的弹窗提示,此处可根据自身项目进行更改
       document.removeEventListener("backbutton", that.eventBackButton, false); //注销返回键
       document.addEventListener("backbutton", that.exitApp, false);//绑定退出事件
       var intervalID = setInterval(() => {
         document.clearInterval(intervalID);
         document.removeEventListener("backbutton", that.exitApp, false);
         document.addEventListener("backbutton", that.eventBackButton, false);
       },2000);
  },
  // 关闭app
  exitApp() {
      var that = this;
      navigator.app.exitApp();
  }
}
//页面离开时销毁监听事件
destroyed() {
  var that = this;
  document.removeEventListener("backbutton", that.exitApp, false);
  document.removeEventListener("backbutton", that.eventBackButton, false);
},
