javascript - 渲染搜索数据时未捕获的不变违规

Question

我正在尝试使用 React 实现搜索。我的逻辑流程有 2 个问题:

• 将输入设置为参数
• 呈现我从服务器获取的数据

我在玩的时候遇到了错误信息

Uncaught Invariant Violation input is a void element tag and must not have children or use props.dangerouslySetInnerHTML.

这是我的代码:

import React, { PropTypes } from 'react';
import withStyles from 'isomorphic-style-loader/lib/withStyles';
import s from './Home.scss';
import AWS from 'aws-sdk';

var GetTech = React.createClass({
  render: function() {
    var createItem = function(item) {
      var csd = new AWS.CloudSearchDomain({
        endpoint: 'mycloudsearch.amazonaws.com',
        region: 'us-east-1'
      });
      var params = {
        query: {this.state.text}
      }
      csd.search(params, function (err, data) {
        if (err) console.log(err, err.stack);
        else {
          console.log(JSON.stringify(data));
        }
      });
    }
    return (
      {this.props.items.map(crateItem)}
    )
  }
});

var FilteredTechs = React.createClass({
  getInitialState: function() {
    return {
      text: '',
      items: []
    };
  },
  handleChange: function(event) {
    console.log(event);
    this.setState({
      text: event.target.value
    });
  },
  handleSearch: function(event) {
    event.preventDefault();
    this.setState({
      items: this.props.items,
      text: ''
    });
  },
  render: function() {
    return (
      <div>
        <form onSubmit={this.handleSearch}>
          <input
            type="text"
            value={this.state.text}
            onChange={this.handleChange}
          />
          <input type="button">Search</input>
        </form>
        <GetTech items={this.state.items} />
      </div>
    );
  }
});


function Home({ techs }) {
  <FilteredTechs />
}

Home.propTypes = {
  techs: PropTypes.arrayOf(PropTypes.shape({
  })).isRequired,
};

export default withStyles(Home, s);

我是 React 的新手。请按照您的意愿告诉我，非常感谢您的提示和评论。非常感谢!

错误很明显:input s 必须是空元素；也就是说，它们必须是自动关闭的。

此语法无效:<input type="button">Search</input>

您想要:<input type="button" value="Search" />

或:<button>Search</button>
