[javascript] view
plaincopy

  

使用：

<input type="text" class="easyui-validatebox" required=true missingMessage="必须输入" data-options="validType:'maxLength[100]'" invalidMessage="最大长度不能超过100"/>

小细节:Unicode编码的汉字是3个字节 。

Oracle 数据库字段指定为varchar2(). 还可以指定其单位为char 还是byte 

为char :

varchar2(3) 可以存 3*2/3= 2个汉字

为byte:varchar2(3)可以存3*1/3=1个汉字
