/**
* 检查送出的form的每个表单元素是否符合填写要求
* @fm 需要检查的form元素。
* @return 如果form的所有表单元素都符合要求，将返回true，
* 否则将会报告不符合的原因，同时返回false。
* 示例：
* <form onsubmit="return checkForm(this)">
*  	<input type=submit>
*  	<input name=email title="请填写邮件地址~email!">
* </form>
* 说明：
* 在form表单元素的title属性中指明此表单元素期望的格式。
* 此格式说明如下
*          请填写邮件地址~email!
* 以最后一个"~"为界，前面的是提示信息，后面是格式信息。
* 格式信息请遵守以下规则：
* [number[f]:][type][!]
* 说明：
* number[f]:	一个数值后面跟一个":",表示此域的文本长度不可以超过指定的数值，如果在数值后面有个f表示固定长度必须为多少位
* type可以是如下表达式
*	 email	邮件地址
*	 int		整数
*	 float	浮点数
*	 date		日期
*	 time		时间
*	 hasChinese     含有中文
*	 allChinese	全部是中文
*	 noChinese	没有中文
*	 /.../[gi]	自定义正则式
* !表示此处文本不可以为空。
* 对于<input type=radio > 格式串为
* "请选择一个选项~!"表示此radio组必须选择一个选项
* "请选择一个选项~"表示此radio组的选项可以不选。
* 对于<input type=checkbox >或者<select multiple></select>格式串的意义为
* 说明信息~min:0max:3
* 对于<select ></select>非multiple类型
* "请选择一个选项~!"表示此select不可以选择第一个选项
* "请选择一个选项~"表示此select可以选择第一个选项
