element-ui 组件二次封装
就考了这个知识点 label绑定的值就是Radio 的 value。我这里选定label与日期绑定。也可以和地址绑定，仔细观察数据。可以发现每一行都是不一样的。然后给radio绑定了一个change事件。通过与这个事件绑定的方法使得label 的值与value的值一致。一致则被选中
<template>
<div class="main">
<el-table
ref="singleTable"
highlight-current-row
:data="tableData"
stripe
border
style="width: 100%"
>
<el-table-column label="单选" width="80">
<!-- TODO：完善单选按钮组件，实现需求（DOM 结构不能修改） -->
<template slot-scope="scope">
<el-radio :label=scope.row.date v-model="currentRow" @change="changeRadio(scope.row)" > </el-radio>
</template>
</el-table-column>
<el-table-column label="日期" width="180">
<template slot-scope="scope">
📅<span style="margin-left: 10px">{{ scope.row.date }}</span>
</template>
</el-table-column>
<el-table-column prop="name" label="姓名" width="180"> </el-table-column>
<el-table-column prop="address" label="地址"> </el-table-column>
</el-table>
<div class="tools">
<el-button @click="setCurrent(tableData[1])">选中第二行</el-button>
<el-button @click="setCurrent()">取消选择</el-button>

http应用
就是基础的node.js
// TODO: 待补充代码
const http=require('http')
const server =http.createServer()
server.on('request',function(req,res){
console.log('访问成功');
})
server.listen(8080,function(){
console.log('8080启动成功');
})

成语学习
-
every()是对数组中每一项运行给定函数，如果该函数对每一项返回true,则返回true。
-
some()是对数组中每一项运行给定函数，如果该函数对任一项返回true，则返回true。
-
some一直在找符合条件的值，一旦找到，则不会继续迭代下去。
-
every从迭代开始，一旦有一个不符合条件，则不会继续迭代下去。
some和every的用法
var arr = [ 1, 2, 3, 4, 5, 6 ];
console.log( arr.some( function( item, index, array ){
console.log( 'item=' + item + ',index='+index+',array='+array );
return item > 3;
}));
console.log( arr.every( function( item, index, array ){
console.log( 'item=' + item + ',index='+index+',array='+array );
return item > 3;
}));
