微信小程序调用组件方法

在父组件中

wxml:

  <stree-togrid-assign id="streeTogridAssign" watchList="{{watchList}}" watchListText="{{watchListText}}"></stree-togrid-assign>

js:

  const streetComponent = this.selectComponent('#streeTogridAssign');

    streetComponent.receiveData();

receiveData为stree-togrid-assign 子组件中自定义的方法
