uni-app中打包App时，boundingClientRect无效的问题

问题:  App内，rect首次无效

const query = uni.createSelectorQuery().in(getCurrentInstance().proxy);

query
.select('#botEnter')
.boundingClientRect(rect => {

})
.exec();

解决办法：采用this

uni
      .createSelectorQuery()
      .in(this)
      .select('#botEnter')
      .boundingClientRect(res => {
        console.log('=====res==botEnter==', res);
        resolve(res);
      })
      .exec();
