Component({
  methods: {
    getRect() {
      this.success = ""; //换一个名字，比如this._success就好使
      //   this.fail = "";
      //   this.complete = "";
      var query = wx.createSelectorQuery().in(this);
      query
        .select(".wrap .content")
        .boundingClientRect(function (res) {
          console.log(res);
        })
        .exec();
    },
  },
});

在组件内部，给组件的success赋值（this.suceess,this.fail,this.complete）,再调用boundingClientRect，回调函数不会执行。

报黄：An SelectorQuery call is ignored because no proper page or component is found. Please considering using `SelectorQuery.in` to specify a proper one.
