【react】map 遍历json数据

数据格式：（此数据写在了getInitialState方法中）

list: [{
     "id":"1",
     "title":"123",
     "time":"2017",
     "person":"cheny0815",
     "type":"type",
     "operation":"operation"
   },{
     "id":"2",
     "title":"456",
     "time":"2017",
     "person":"cheny0815",
     "type":"type",
     "operation":"operation"
   },{
     "id":"3",
     "title":"789",
     "time":"2017",
     "person":"cheny0815",
     "type":"type",
     "operation":"operation"
   }]

页面中遍历方法（此处用this.state.list便可以取到值）

<table>
    <tbody>
        <tr className="first_tr">
          <td>内容</td>
          <td>发起人</td>
          <td>类型</td>
          <td>时间</td>
          <td>操作</td>
        </tr>
        {
          this.state.list.map(function(name){
            return (
                <tr key={name.id}>
                  <td>{name.title}</td>
                  <td>{name.person}</td>
                  <td>{name.type}</td>
                  <td>{name.time}</td>
                  <td>{name.operation}</td>
               </tr>
            )
          })
        }
    </tbody>
</table>

使用map遍历时,需要给子元素添加一个key,作为唯一的标识,而且key值必须要连续,否则会报错
