继上个月使用weui以后，我把react和weui结合起来做了一个表单，对输入的内容进行检验，检验内容有姓名、学号、手机号。

引用的文件如下，均为weui或react的文件：

<link rel="stylesheet" href="css/weui.css"/>
<link rel="stylesheet" href="css/example.css"/>
<script src="js/react.js"></script>
<script src="js/react-dom.js"></script>
<script src="js/browser.min.js"></script>

核心代码如下：

<body ontouchstart>
 <div id="container">
 </div>
 
<script type="text/babel">
  var MyForm = React.createClass({
    getInitialState: function() {
      return {
      };
    },
    handleNumber: function(e) {
      var value = e.target.value;
      var error = '';
      if(!(/[0-9]{12}/.test(value))) {
        error = 'weui_cell_warn';
      }
      this.setState({
        number: value,
        numberError: error
      });
    },
    handleName: function(e) {
      var value = e.target.value;
      var error = '';
      if(value.length < 2) {
        error = 'weui_cell_warn';
      }
      this.setState({
        name: value,
        nameError: error
      });
    },
    handlePhone: function(e) {
      var value = e.target.value;
      var error = '';
      if(!(/^1[3|4|5|8]\d{9}$/.test(value))) {
        error = 'weui_cell_warn';
      }
      this.setState({
        phone: value,
        phoneError: error
      });
    },
    handleName2: function(e) {
      var value = e.target.value;
      var error = '';
      if(value.length < 2) {
        error = 'weui_cell_warn';
      }
      this.setState({
        name2: value,
        name2Error: error
      });
    },
    render: function() {
      return (
<div>
