问题描述
[在taro1.2.2 (只考虑微信小程序)中使用不了 createIntersectionObserver]

复现步骤
两种方法都不行

  1. 第一种 :
componentDidMount() {
    this.observer = wx.createIntersectionObserver(this);
    this.observer.relativeTo('#container')
    .observe('.search_sticky_box', (res) => {
      console.log(res);
      console.log("aabbbcc");
    })
  }

错误
回调不执行,没有打印任何日志
2. 第二种 :

  componentDidMount() {
    this.observer = this.createIntersectionObserver();
    this.observer.relativeTo('#container')
    .observe('.sentinel_for_search', (res) => {
      console.log(res);
      console.log("aabbbcc");
    })
  }

错误
报错如下,也没有执行回调

期望行为
[可以使用API]
