1.样式

validatebox(验证框)的设计目的是为了验证输入的表单字段是否有效。如果用户输入了无效的值，它将会更改输入框的背景颜色，并且显示警告图标和提示信息。该验证框可以结合form(表单)插件并防止表单重复提交。

2.练习1：验证输入字符长度及非空

<!DOCTYPE html> 
<html> 
<head> 
<meta charset="UTF-8"> 
<title>validatebox</title> 
<!-- 引入css文件 --> 
<link rel="stylesheet" href="themes/default/easyui.css" rel="external nofollow" rel="external nofollow" rel="external nofollow" type="text/css"></link> 
<link rel="stylesheet" href="themes/icon.css" rel="external nofollow" rel="external nofollow" rel="external nofollow" type="text/css"></link>   
<!-- 引入js文件 --> 
<script type="text/javascript" src="js/jquery.min.js"></script> 
<script type="text/javascript" src="js/jquery.easyui.min.js"></script> 
<script type="text/javascript" src="js/easyui-lang-zh_CN.js"></script> 
</head> 
<body> 
  姓名：<input id="validateboxID"/><p/> 
</body> 
<script type="text/javascript"> 
 $("#validateboxID").validatebox({ 
  required:true, 
  validType:['length[1,6]','zhongwen'] 
 }); 
</script> 
</html>

 <!-- 邮箱：<input id="emailID"/><p/> 
 密码：<input id="passwordID"/><p/> --> 
</body> 
<script type="text/javascript"> 
 $("#validateboxID").validatebox({ 
  required:true, 
  validType:['length[1,6]','zhongwen'] 
 }); 
 $.extend($.fn.validatebox.defaults.rules,{ 
  zhongwen:{ 
   validator:function(value){ 
    //如果符合中文 
    if(/^[\u3220-\uFA29]*$/.test(value)){ 
     return true; 
    } 
   }, 
   //如果不符合中文，以下就是提示信息
