呵呵，，不必自定义、就使用原来的属性,例如:、在js中取出验证规则进行验证、然后给出提示。下面是自写的一个验证表单通用js、由于时间关系尚未完善、作为参考提供给你：
//此js是验证规则是固定的：
//如想使用form表单元素自己提供的验证规则：
/*
- 如需效验ip或密码、请将密码id设置为:password、确认密码id设置为：confirmPassword、ip的id设置为ip、效验代码默认将这3个元素id视为:password\confirmPassword\ip、或在效验代码中将这3元素id修改成你自己定义的元素id,否则将无法效验
- */
//oForm:Form表单对象 、值: HTML表单
//minLength:最小长度 、值：大于0的整数
//maxLength:最大长度 、值：无穷大的整数
//isLength:是否效验最大、最小长度、值：true/false
//isEmpty:是否效验是否为空值 、值：true/false
//isSpecial是否效验是否包含特殊字符、值： true/false
//isSpace:是否效验是否包含空格 、值：true/false
//isNotEqual是否效验是否相等、值：true/false
//isNumber是否效验全由数字组成、值：true/false
//isDataFormat是否效验日期格式、值：true/false
//isEmailFormat是否效验邮箱格式、值：true/false
//isPhoneFormat是否效验手机格式、值: true/false
//isPhoneTeleFormat是否效验电话格式、值: true/false

//isMenword是否效验全由汉字组成、值：true/false
//暂未效验日期、邮箱、手机、电话、字母、汉字或其他需求、如有需求可自行实行
//倍数:用于设定textarea元素的字符最大长度,由于textarea元素有可能输入比较多的字符、所以使用自定义的最大长度maxLength乘倍数multiple、[maxLength * multiple]、默认自定义的最大长度maxLength的10倍
