1、此按钮添加到“页面” tab页；

2、需要编辑页面才能看到效果；

3、javascript执行不来，不知道怎么回事；

最后改用urlaction

    <CustomAction
  Id="SelectTemplate"
  GroupId="SiteActions"
  Location="Microsoft.SharePoint.StandardMenu"
  Sequence="1000"
   Title="自定义" Description=描述"
  ImageUrl="/_layouts/images/visualupgradehh.png"
   Rights="ManagePermissions">
        <UrlAction Url="~site/_layouts/settings.aspx"/>
    </CustomAction>
