Uncaught TypeError：无法读取未定义的属性“状态”

问题描述

 未捕获的类型错误：无法读取未定义的属性'状态'
  

out

class Accordion extends React.Component {


解决方案

您需要绑定这个。

this.onSelect - > this.onSelect.bind（this）

this.enhanceSection - > this.enhanceSection.bind（this）

I am trying to change from React.createClass to React.Component, but I am getting below error.

Uncaught TypeError: Cannot read property 'state' of undefined

I googled for the error but an not able to figure it out

class Accordion extends React.Component {

解决方案

You need to bind this.

this.onSelect -> this.onSelect.bind(this)

this.enhanceSection -> this.enhanceSection.bind(this)
