JS 获取Button控件的提交类型

 <script type="text/javascript">
<!--获取button控件的类型--->   
        function isAuditOrCancel(value) {
            document.getElementById("audittype").value = value;
        }
 </script>

<!--声明变量，到后台接收---> 
<%: Html.Hidden("audittype")%>

 <li>
   <div class="buttonActive">
    <div class="buttonContent">
     <button type="submit" onclick="isAuditOrCancel('audit')">
       提交审批
     </button>
    </div>
   </div>
 </li>
 <li>
  <div class="buttonActive">
      <div class="buttonContent">
       <button type="submit" onclick="isAuditOrCancel('cancel')">
          撤消
       </button>
      </div>
  </div>
</li>
<li>
  <div class="button">
     <div class="buttonContent">
       <button type="button" class="close">
        关闭
       </button>
     </div>
   </div>
 </li>

后台获取：

 string audittype = Request.Form["audittype"];
if (audittype == "cancel")
            {
                string refreshTab = Request.Form["refreshTab"];
                WorkflowCancel(BusinessId);
                return ReutrnSuccessStr("200", "撤销成功", refreshTab, "closeCurrent");
            }
else if(audittype=="audit" )
{
              string taskid = Request["taskid"];
                string Remark = Request.Form["Remark"] == null ? "" : Request.Form["Remark"];
                Remark = Maxuni.Util.StringUtil.GetFilerStr(Remark);
                string tabname = Request.Form["tabname"] == null ? "" : Request.Form["tabname"];
                string DealwithResult = Request.Form["DealwithResult"] == null ? "1" : Request.Form["DealwithResult"];
                string jumpWorkflowid = Request.Form["NodeRoleName"] == null ? "" : Request.Form["NodeRoleName"];
                bool isSendMsg = Request.Form["isSendMsg"] == "on" ? true : false;
                WorkflowJumpByRole(taskid, DealwithResult, jumpWorkflowid, Remark.Replace("'", """), isSendMsg);
                string IsHasNextNode = Request.Form["IsHasNextNode"];
                if (IsHasNextNode == "no" && DealwithResult == "1")//如果审批已完成
                {
                    AuditCompleteSendMessage(taskid);
                    SaveOProcessRequisitionEmit(BusinessId, 0, mouldNo);
                }
                return ReutrnSuccessStr("200", "提交成功", "", "closeCurrent");
            }
}
