常用JS验证控件

jskey_validator.js

View Code

/**
* 名称命名规则说明
* 首字母大写,非常少用的尽可能用Custom
* 注:如果添加了方法形式的,记得在Validate中的case中补上
* --------------------------------------------------------
* skey:增加了默认的msg提示,以大量减少页面上的msg属性
* skey:修改使支持非表单形式的元素值校验,如根据父元素ID校验所有需要校验的子元素
* skey:增加alertMsg提示,弹出的信息可以与页面显示信息不同,默认与msg一致
* skey:修改部分正则表达式,并重命名所有内部函数
* skey:删除从未使用的部分验证,并作了部分小修改
* 最后更新时间:2012-05-13 23:30
