[推荐]通用控件校验函数

PHP代码:

--------------------------------------------------------------------------------
<INPUT type="button" name="b_splcJbxx_new" value="test" onclick="validate('RS','splcValue.String(DM_WSZL)','文书种类','R','splcValue.String(MC_SPLC)','审批流程名称');return document.returnValue">

--------------------------------------------------------------------------------

对于每一个控件是这样定义的
需要三个参数
1.校验类型
2.控件name
3.中文含义
