如何隐藏“保存”按钮

请问如何隐藏表单上的“保存”按钮？

1 全局隐藏

 修改Portal\WFRes\_Scripts\MVCSheet\MvcSheet.js，搜索如下代码，大概594行，把this.SaveAction屏蔽掉。
 然后增加\Portal\MvcSheet.master 文件中MvcSheet.js引用的版本号。

//添加默认的事件
      AddDefaultActions: function () {
          this.Actions.splice(0, this.Actions.length,
                  this.RetrieveInstanceAction,
                  //this.SaveAction,
                  this.ViewInstanceAction,
                  this.PreviewParticipantAction,
                  this.PrintAction,
                  this.ViewedAction,
                  this.CancelInstanceAction,
                  this.SubmitAction,
                  this.RejectAction,
                  this.FinishInstanceAction,
                  this.ForwardAction,
                  this.AssistAction,
                  this.ConsultAction,
                  this.CirculateAction,
                  this.AdjustParticipantAction,
                  this.LockInstanceAction,
                  this.UnLockInstanceAction,
                  this.CloseAction
              );
      },

2 个别表单隐藏
 表单加载完成后直接用jq隐藏，简单粗暴

$.MvcSheet.Loaded = function (sheetInfo) { 
  $("li[data-action='Save']").hide();
}

非常感谢！
