【uni-app框架】组件传参props传入对象之后报的错误：undefined is not an object (evaluating 'event.detail.$parent.$childre

错误的核心代码：**undefined is not an object (evaluating 'event.detail.$parent.$children'); \[Component\] Event Listener Error @ wx-view\#(anonymous)**

**错误分析：出现这个的原因其实就是父组件传入的数据类型结构和子组件传入的数据结构不一致，而导致undefined 错误类型：**

**还有一个特殊情况：计算属性传入props传参的时候，如果对象稍微复杂点【如：\[\{\}\]】类型之后，直接计算属性传入参数也会报underfined错误，但是在data中做一个初始化之后如：wallet：\[\{\}\] 之后，计算属性在计算会发现正常【总而言之，APP端太多的问题了，所以各种用法还是不断测试保守用即可----毕竟Vue还是专门为H5开发的，所以app只能将就！】**
