我如何在Reactjs中遍历表行和单元格
问题描述:
我对Reactjs还是很陌生,我有一个从我的数据库中加载json的组件,看起来像这样
I am pretty new to Reactjs and i have a component that loads json from my db that looks like this
Array[2]
0: Object
_id: "56cf587fe46adb3b8960afe2"
price: 2000
title: "ps3"
url: "www.google.com"
__proto__: Object
1: Object
_id: "56db2bd434df9046e0643d22"
price: 499
title: "HENRIKSDAL"
url: "http://www.ikea.com/se/sv/catalog/products/S59847817/"
__proto__: Object
length: 2
__proto__: Array[0]
我要做的是将数据加载到看起来像这样的表上
what i want to do is to load the data on to the table that looks like this
//start of loop
<tr>
<td className="col-sm-8 col-md-6">
<div className="media">
<div className="media-body">
<h4 className="media-heading"><a href="#">Product name</a></h4>
</div>
</div></td>
<td className="col-sm-1 col-md-1" styles="text-align: center">
<input type="number" name="quantity" min="1" max="10" className="form-control"/>
</td>
<td className="col-sm-1 col-md-1 text-center"><strong>500:-</strong></td>
<td className="col-sm-1 col-md-1 text-center"><strong>$14.61</strong></td>
<td className="actions" data-th="">
<button className="btn btn-info btn-sm"><i className="fa fa-refresh"></i></button>
<button className="btn btn-danger btn-sm"><i className="fa fa-trash-o"></i></button>
</td>
</tr>
<tr>
<td> </td>
<td> </td>
<td> </td>
<td><h3>Total</h3></td>
<td className="text-right"><h3><strong>$31.53</strong></h3></td>
</tr>
//end of loop
但是我不知道如何遍历数组,因此它将为数组中的每个对象创建一个表行.有什么建议?
But i don't know how to iterate through the array so it will create a tablerow for each object in the array. Any suggestions?
答
您可以映射数组并将数据传递到html
You can map the array and pass the data through to the html
{this.state.data.map(( listValue, index ) => {
return (
<tr key={index}>
<td>{listValue.id}</td>
<td>{listValue.title}</td>
<td>{listValue.price}</td>
</tr>
);
})}
