redux的入門學習 分離的鞏固

1:新建乙個兩個頁面   乙個頁面放使用者的新增    乙個頁面使用者的列表  

import react,  from 'react'

export default class useradd extends component 
}

import react,  from 'react'

import "../css/user.css";
export default class userlist extends component 
}

let   initstate = ]

}let userreducer =(state=initstate,action)=>
export default userreducer;

import   from  "redux"

import numreducer from "../reducer/numreducer"
import userreducer from "../reducer/userreducer";
let allreducer = combinereducers();
export default createstore(allreducer);

import react,  from 'react'

import "../css/user.css";
import store from "../store";
export default class userlist extends component 
render() 刪除)
})})
}}

import react,  from 'react'

import store from "../store";
export default class useradd extends component 
})}}>新增)}
}

let   initstate = ]

}let userreducer =(state=initstate,action)=>
}return state;
}export default userreducer;

常量action/index.js中

export  default

action/useraction.js中

import   actiontype  from  "./index";

let add = (playload)=>
}export

import   actiontype from  "../action"

let initstate = ]
}let userreducer =(state=initstate,action)=>
}return state;
}export default userreducer;

import react,  from 'react'

import store from "../store";
import from "../action/useraction"
export default class useradd extends component ));
}}>新增)}
}

action/index.js中 

export  default

import   actiontype  from  "./index";

let add = (playload)=>
}let del = (playload)=>
}let init =(playload)=>
}export

import   actiontype from  "../action"

let initstate = 
let userreducer =(state=initstate,action)=>
case actiontype.deleteuser:
return 
case actiontype.inituser:
return 
}return state;
}export default userreducer;

import react,  from 'react'

import "../css/user.css";
import store from "../store";
import from "../action/useraction"
export default class userlist extends component 
componentdidmount(),]
store.dispatch(init(list));
this.forceupdate();
}render() 
}>刪除

}

Redux 入門學習

2014年 facebook 提出了 flux 架構的概念，引發了很多的實現。2015年，redux 出現，將 flux 與函式式程式設計結合一起，很短時間內就成為了最熱門的前端架構。redux 是乙個改變狀態 state 的模型，這個模型通過乙個單向操作的方式來改變狀態。redux 和 react...

redux的入門學習 使用react redux

1 使用react redux 簡化的 頁面端的使用 業務的分離的分離不會變 2 減少store的引入 3 簡化state的呼叫 和 state修改的方法的使用 類似vuex中 mapstate和mapmutation 第一步 安心 npm i react redux 第二步 引入和使用 全域性配置...

redux之入門學習

總結 1 頁面上view通過store.dispatch 發出 action，action統一在actioncreators.js檔案中，2 store 收到 action 以後，執行reducer.js中對應的方法，reducer是乙個函式，它接受 action 和當前 state 作為引數，返回...
