快应用可通过id属性拿到组件元素的
类似于:
const el = this.$element('elId')

虽然有点挖坟,但考虑到可能还是会有和我们历史老项目的人,如果搜到了这个,好消息是现在快应用是有了获取组件元素的API:组件公共方法 ,不过1.x的taro文档没有提及怎么获取当前快应用组件实例,可以在taro组件内的 this.$scope 来代替快应用组件的 this

// 假定内部想要获取的快应用组件元素id是"abc" 
// 注意先做环境判断,毕竟是快应用才有的API
if (IS_QUICKAPP) {
  console.log(this.$scope.$element("abc"));
}
