一、JS添加代码，判断是否有OnSubmit事件

文件位置：YZSoft/Forms/src/Validator.js

//=====判断是否有OnSubmit事件=====        if (typeof (OnSubmit) != 'undefined')        {            var func = OnSubmit;            if (func(validationGroup) === false)                return false;        }

二、OnSubmit方法

代码位置：需要判断的表单中

三、ajax一般处理程序

<%@ WebHandler Language="C#" Class="CollectionManagement" %>using System;using System.Web;using System.Linq;using System.Collections.Generic;using System.Collections;public class CollectionManagement : IHttpHandler {        public void ProcessRequest (HttpContext context) {                string PID=context.Request["PID"];        //PID = "GC422444";        //string json = "{\"P\":\"F\"}";        string flag = "true";        using (CollectionManagementDataClassesDataContext cm = new CollectionManagementDataClassesDataContext())        {            List
      
        P = cm.EngineeringManagement.Where(r => r.ProjectID == PID).ToList();            if (P.Count != 0)            {                flag = "false";            }        }        context.Response.Write(flag);        context.Response.End();    }    public bool IsReusable    {        get        {            return false;        }    }    }
