日常JS页面验证封装
/************************************ JSP页面输入有效性校验* author:* create date:* update date:* update content: 此文件在原先使用文件checkvalue.jsp基础上，结合原先的使用经验做了如下改进* 1 增加函数CheckSpecChar(FormName)，直接校验整个form的所有输入控件是否包含非法字符。* 2 函数CheckInputValue原先传入参数输入框内容，改为输入框对象名称，这样一旦校验不通过，光标可以定位到对象。* 3 优化日期校验，原先对日期格式只校验输入字符，没有校验长度以及yyyy-mm-dd格式中年月日各自是否满足要求。* 4 优化Email格式校验* 5 原先输入框允许为空，同时如果输入内容有最短长度限制时候，无法校验，现已修改，能够支持。** 增加系数Rate类型，不能大于1* 增加时间Time类型，24h:mi格式*********************************///提交表单时清理所有的非隐藏表单元素值的左右空格并校验是否含有非法字符--liuchuangfunction submitclean(FormName){var str = "'<>"";
