/*
函数名称：limitLength(value, byteLength, title, attribute, spanid, lang)
作用：限制输入框的字节输入长度
value: 输入字符串；
byteLength：数据库字节长度；
title：字段中文名称；
attribute：属性名称；
spanid： 需要显示数字的span控件名称
lang：提示语言种类，“cn”代表中文，“en”代表英文

使用方法说明：
添加 （1） onkeyup="limitLength(this.value,100,'名称','name')"
     （2） id="name" 或【struts标签】styleId="name"
注意：id名称和 attribute属性名称要一样
例子：
<textarea  name="explain" id="explain" onkeyup="limitLength(value,5,'语义说明','explain','cn')" >   </textarea>
<input type="text" name="txt_explain"  id="txt_explain" onkeyup="limitLength(value,5,'explain','txt_explain','en')" >
