1.父子传值,父组件通过属性的方式去给子组件传递值,子组件在properties属性去接收父组件传递过来的值:
父组件部分:
<view class="pcolor"><customer id="child" bind:changSex="changSex" sex="{{sex}}" checked="{{checked}}"></customer><view>父组件的值:{{sex}}</view>
</view>
子组件部分:
properties: {sex:{type:String,value:'女'},checked:{type:Boolean,value:false}},通过 this.triggerEvent('changSex','女')去修改父组件的值
2.组件之间的传值:
需要使用pubsub-js这个插件,下载npm install pubsub-js
在组件1 引入import PubSup from 'pubsub-js', 通过PubSup.publish('info',{name:'zhansgan',age:20});去传递值
在组建2 引入import PubSup from 'pubsub-js',在生命周期去接收
lifetimes:{attached() {PubSup.subscribe('info',(name,value)=>{console.log(name,value)})}},
3.页面间的传值:
跳转页面:
jump:function() {wx.navigateTo({url: '/pages/list/list',events:{send1:(e)=>{console.log(e)}},success:(res)=>{console.log(res)res.eventChannel.emit('send',{name:'zhangsan'})}})},
接收页面:
onLoad() {const openerEventChannel = this.getOpenerEventChannel();console.log('111')openerEventChannel.on('send',(res)=>{console.log(res)})openerEventChannel.emit('send1',{age:10})}
