AjaxMethod 的问题


 [AjaxPro.AjaxMethod]
    public void Mark(string strTerm,string bCode) 
    {
        PartManageSyst.Model.AppraisalMark modelMark = new PartManageSyst.Model.AppraisalMark();
        int total = 0;
        int edit = 0;
        if (!string.IsNullOrEmpty(strTerm)) 
        {
            if (strTerm.Contains(',')) 
            {
                string[] strList = strTerm.Split(',');
                if (strList != null && strList.Length > 0) 
                {
                    int count=strList.Length;
                    for (int i = 0; i < count; i++) 
                    {
                        if (!string.IsNullOrEmpty(strList[i]) && strList[i].Contains('|')) 
                        {
                            total++;
                            string[] strArray = strList[i].Split('|');
                            if (strArray != null && strArray.Length > 0) 
                            {   
                                modelMark.bCode = bCode;
                                modelMark.cCode = strArray[2];
                                modelMark.OwnGrade = strArray[0];
                                modelMark.OrganizationGrade = strArray[1];
                                modelMark.OrgTime = DateTime.Now;
                                modelMark.OwnerTime = DateTime.Now;
                                modelMark.Year = DateTime.Now.Year.ToString();
                                PartManageSyst.BLL.AppraisalMark managerMark = new PartManageSyst.BLL.AppraisalMark();
                                int temp=managerMark.Add(modelMark);
                                if (temp > 0)
                                {
                                    edit++;
                                }
                            }
                        }
                    }
                }
            }
        }
        if (edit.Equals(total) && !edit.Equals(0))
        {
            Page.ClientScript.RegisterStartupScript(this.GetType(), "alert", "<script>alert('评分成功!')</script>");
        }
        else 
        {
            Page.ClientScript.RegisterStartupScript(this.GetType(), "alert", "<script>alert('并未全部评分成功,请重新添加!')</script>");
        }
    }
  为什么弹提示框弹不出来呢？调试的话，它也走“Page.ClientScript…” 然后就报错了…麻烦高手给看看，讲讲…
