1、子组件调用父组件方法

     子组件this.triggerEvent('finish');

    startShare(e) {let url = config.apiUrl + "/business/lzShare/edit";let data = this.data.currentData;util.httpPut(url, data).then((res) => {this.triggerEvent('finish');console.log(res.result);})},

父组件监听

bind:finish="finishShare"

    <view class="padding flex flex-col flex-space-between " ><share bind:finish="finishShare"  data="{{shareData}}"  style="margin-top:40px"></share></view>

2、父组件调用子组件方法

父组件index.json引用子组件

 父组件引用子组件，子组件设置id值 

调用

this.selectComponent('#filedir')

    saveMoveData(e) {this.filedir = this.selectComponent('#filedir')let url = config.apiUrl + "/business/lzDocs/changeDir";let param = {id: this.data.selectData.id, parentId: this.filedir.getSelect().id}util.httpPost(url, param).then((res) => {this.loadData();this.setData({showMove : false})})},

子组件的方法

// components/filedir/filedir.js
const icon = require('../../utils/icon.js');Component({/*** 组件的属性列表*/properties: {data:{}},observers: {'data': function(newVal, oldVal) {console.log("newVal====", newVal)this.setData({currentData: newVal, dirData: newVal})this.setData({navData: []})}},/*** 组件的初始数据*/data: {navData:[],currentData:[],},/*** 组件的方法列表*/methods: {getSelect() {if (this.data.navData.length == 0) {return null;} else {return this.data.navData[this.data.navData.length-1];}},}
})
