[Vue warn]: Avoid mutating a prop directly since the value will be overwritten whenever the parent component re-renders. Instead, use a data or computed property based on the prop's value. Prop being mutated: "openFlag" 此错误出现的原因是:vue设计是单向数据流,数据的…
[Vue warn]: Avoid mutating a prop directly since the value will be overwritten whenever the parent component re-renders. Instead, use a data or computed property based on the prop's value. Prop being mutated: 'mode' 这个错误是我在子组件里操作父组件传过来的值时报的错,看了官方文档说要…

今天在做Vue的时候,子组件关闭的时候,报如下错误 报错:vue.esm.js?65d7:610 [Vue warn]: Avoid mutating a prop directly since the value will be overwritten whenever the parent component re-renders. Instead, use a data or computed property based on the prop's value. Prop being m…
Avoid mutating a prop directly since the value will be overwritten whenever the parent component re-renders. 这个错误是因为,因为我们直接修改父组件传递过来的参数,这样会存在影响外部 组件的风险. 解决方案: 在组件内部再构建一套属性域,来存储父组件传递过来的参数,从而与外界解耦…
报错:Avoid mutating a prop directly since the value will be overwritten whenever the parent component........ 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) 不能直接对父组件传来的值进行双向绑定,要先子组件里定义新的变量…
vue不推荐直接在子组件中修改父组件传来的props的值,会报错 [Vue warn]: Avoid mutating a prop directly since the value will be overwritten whenever the parent component re-renders. Instead, use a data or computed property based on the prop's value. Prop being mutated: "result&…
对于父子组件之间的互相传值,报错如下: [Vue warn]: Avoid mutating a prop directly since the value will be overwritten whenever the parent component re-renders. Instead, use a data or computed property based on the prop's value. Prop being mutated: "propTextTip" 大概…
最近做项目,遇到一个问题 列表滚动,上拉加载功能 采用了better-scroll 插件,将better-scroll 封装成组件,采用父组件传递值给子组件的方式,子组件 采用$emit 方式 通知父组件值得变化,所以在父组件上获取总的数据(ajax),此时问题出现了,只要一上拉加载,就会报错,原因是改变了,父组件传递过去的总的数据. [Vue warn]: Avoid mutating a prop directly since the value will be overwritten wh…
原文地址:http://www.cnblogs.com/kidsitcn/p/5409994.html 所有的vuejs组件都是被扩展的vue实例: var MyComponent = Vue.extend({ //扩展选项对象 }) var myComponentInstance = new MyComponent(); 每个Vue实例都会代理这个实例的data属性对象里的所有属性: var data = { a: 1 } var vm = new Vue({ data: data }) vm…
