[自定義組件](https://developers.weixin.qq.com/miniprogram/dev/framework/custom-component/behaviors.html) [TOC] # behavior > 用于組件間代碼共享的特性 ## 相同的屬性 ``` var common = Behavior({ properties:{ title:String, content:String, src:String } }) export {common}; ``` ## 引用 ``` import {common} from "../common" Component({ behaviors:[common] }) ``` # 重點 ## 子組件向父組件傳參 ``` var behavior = this.data.isLike; this.triggerEvent('isLike',{ behavior }) ``` ## 父組件接受 ``` <v-like like="{{like}}" count="{{count}}" bind:isLike="onLike"></v-like> //獲取組件中的傳值 onLike(e) { var behavior = e.detail.behavior; }, ``` ## attached() > //當組件觸發 attached 生命周期時，會依次觸發 my-behavior 中的 attached 生命周期函數和 my-component 中的 attached 生命周期函數
