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>

结果:

3.练习2:自定义规则作为输入框验证规则


<!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/> 
 <!-- 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 
 message:'姓名必须全为中文' 
 } 
 }); 
</script> 
</html> 

结果:

4.练习3:验证邮箱


<!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> 
 邮箱:<input id="emailID"/><p/> 
</body> 
<script type="text/javascript"> 
 $("#emailID").validatebox({ 
 required:true, 
 validType:['length[1,30]','email'] 
 
 }); 
</script> 
</html> 

结果:
