vue项目中如何动态的设置iframe的高度的呢，这里主要用到了监听的功能，页面高度变化时，设定的动态高度也会相应的改变。

### template中： ###

### data()中： ###

fullHeight: document.documentElement.clientHeight , 
      timer: true

### watch中： ###

watch: {
         
        fullHeight(val) {
         
          if (!this.timer) {
        //防止多次触发监听页面卡顿 
            this.fullHeight = val; 
            this.timer = true; 
            let that = this; 
            setTimeout(function() {
         
              that.timer = false; 
            }, 400); 
          } 
        } 
      },

### mounted中： ###

window.onresize = () => {
         
          return (() => {
         
            window.fullHeight = document.documentElement.clientHeight; 
            this.fullHeight = window.fullHeight ; 
          })(); 
        };
