/*
*V2.0 (2008-02-14)马超修改内容
*  1、修改Form中对象的最大长度判断
*     ①去掉验证中的textarea属性
*     ②根据maxlength或maxLength属性进行判断（文本框的最大长度属性应为maxLength）
*     ③根据validrule.cn来判断汉字，一个汉字为两个字符，且最大长度小于Form中对象的实际长度时才提示，等于最大长度时不提示
*     ④文本框也可以进行最大长度的验证，通过maxLength属性，最大限度防止字符串超常引起SQL语句错误
*V2.1 马超修改内容
*  1、加入“非汉字”的验证方式（validrule.nocn）
*  2、加入“月-日”的验证方式（validrule.monthday）
*V2.2 韩林平修改内容
*  1、注释掉原2.0版本中一个汉字为两个字符的验证方式，原因：此验证方式不友好，用户还能录入但是实际已经超过录入上限。
*V3.0 (2012-02-17)马超修改内容
*  1、解决验证方法浏览器兼容性问题（Firefox等浏览器此验证函数永远返回true，等于无法进行验证，原因_elem.vmode在Firefox中无法获得vmode的值，原写法不规范只支持ie）
*     ①将所有获取对象自定义属性值的语句例如：从“_elem.vmode”改成“_elem.getAttribute("vmode")”
*     ②加入“getElement(strID)”方法用于获取对象
*V3.1 (2012-04-25)杨彦彬修改内容
*  1、添加doValidateInfo()校验方法，用于将全部不合格校验信息集中展示。保留原来逐条校验功能。
*V3.2 (2012-07-12)马超修改内容
*  1、修改float、double的验证正则表达式，原有正则表达式存在bug，原为“/^((([-\+]?\d+)(\.\d+))|(\.\d+)|(\d*))?$/”现改为“/^([-\+]?(((\d+)(\.\d+))|(\.\d+)|(\d*)))?$/”。原bug为输入“-11”或“-.5”会验证不过去。
*V3.3 (2012-08-06)马超修改内容
*  1、加入NoSingleQuotes的验证正则表达式，验证不含有单引号的字符串。
*V3.4 (2013-01-14)杨飞修改内容
*  1、加入decimal的验证正则表达式，小数点后最多3位 。
*  2、加入decimalStr的验证正则表达式，验证输入的是符合如（15,2）格式的字符串。
*
