Avoid mutating a prop directly since the value will be overwritten whenever the parent component re

Vue报错记录原因分析：这是父子组件传值时报的错，先看一下代码：父组件：子组件：props:{loading:{type:Boolean,default:false}},父组件通过:loading方式传值，子组件props接收，然后在里使用这个值。报错的原因：Vue使用单项数据流，为了防止子组件修改父组件的值，子组件应该在接收了父组件的值之后，在自己的data或者computed里定义一个变量来使

Vue2.0 饿了么报错：Avoid mutating a prop directly since the value will be overwritten whenever

报错原因：所有的prop都使得其父子prop之间形成了一个单向下行绑定：父级prop的更新会向下流动到子组件中，但是反过来则不行。（父组件更新，子组件中的prop值也会更新，但子组件不能修改由父组件传递过来的值）解决办法：定义一个本地的data属性并将这个prop用作其初始值，同步对组件的修改，再通知父组件更新相关代码：{{desc.all}}47{{desc.positive}}50{{desc

Vue2.0 之props是数据绑定出错

背景在使用Vue进行组件开发时，对于父组件传递过来的props属性，在子组件内部对这个值进行了更改，就会出现如下的错误信息：[Vuewarn]:Avoidmutatingapropdirectlysincethevaluewillbeoverwrittenwhenevertheparentcomponentre-renders.Instead

一句话总结：基于CNN，用启动子序列预测mRNA丰度研究背景稳态的mRNA丰度由很多调控因子所决定，重点在于选用哪种关键机制来准确预测mRNA丰度。相关研究表明启动子序列单独解释了人类大部分基因表达的变异。本文的方向是希望仅用基因序列的信息预测mRNA丰度,这里结合的是启动子序列和mRNA稳定性相关序列特征的信息（图1）。图1：:Xpresso输入输出概览模型结构Xpresso的结构就是传统的卷积
