vue的computed的小结

//初始化数据
data() {
    return {     
          testComputed: {value:'v1'}
    };
  },

//1.赋值testComputed，则预期会打印computed
computed: {
    test() {
      console.log('computed');
      return this.testComputed;
    }   
  },

methods: {

click() {
        this.testComputed = null;   
    },
}
 //点击click之后，则会执行computed里的test方法，并打印“computed”
