/*
命名规则为需要一个label和input或select,textarea对应，前缀都为三位后缀应当相同
label的前缀应当为"lbl",例子见后

第一位			第二位		第三位					第四位
必须输入标志		数据类型种类	总长度					小数部分长度
  Y或者N  		数字型	   （如是数字型则包括小数点）
			浮点	N
			整数	I
			长整数	L
			字符型	S
			日期	D
			时间	T
			日期时间E
			按钮	B

	各位之间用逗号（","）隔开
	如：	要求的数据			表示为
		 必须输入的整数			Y,I
		必须输入的浮点精度为4.2	Y,N,4,2

通过关键字dwRules给元素添加控制
