Vue监听页面放大缩小事件

Vue监听页面放大缩小事件  ，使用window.addEventListener，methods中方法

 ChangeWin(){
      let ratio = this.getRatio();
      let Pwidth = window.screen.width*this.getRatio()/100;
      let PHeight = window.screen.height*this.getRatio()/100;
       //1920 *1080
      if (ratio == 100) {
        if (Pwidth == '1920' && PHeight == '1080') {
          this.$el.style.setProperty('--mg_top1', '3.5vh')
        }
      }
    }

使用：

mounted() {
    window.addEventListener('resize', this.ChangeWin);
  },
