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({
