SharePoint 2010/2013 通过List Item的内容菜单(BCD)来拷贝Item

本文讲述SharePoint 2010/2013 通过List Item的内容菜单(BCD)来拷贝Item的方案。

项目中有时会遇到需要在原有列表项的基础上拷贝列表项进行编辑并保存的的需求，本文将阐述如何实现这一需求。

效果为：

思路是使用List Item的内容菜单(BCD) 和 ashx ，增加一个copy item的菜单(CopyMenuElement)：

<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
  <CustomAction
   Location="ScriptLink"
  ScriptSrc="~site/_layouts/15/CopyItem/jquery-1.11.0.min.js"
  Sequence="99" />
  <CustomAction
     Location="ScriptLink"
    ScriptSrc="~site/_layouts/15/CopyItem/CopyItem.js"
    Sequence="100" />
  <CustomAction
     Id="65695319-4784-478e-8dcd-4e541cb1d682.CopyItem"
     RegistrationType="List"
     RegistrationId="100"
     Location="EditControlBlock"
     Sequence="10001"
     Title="Copy Item"> 
    <UrlAction Url="javascript:CopyItemById(‘{ListId}‘, ‘{ItemId}‘,‘{SiteUrl}‘)" />   
  </CustomAction>
</Elements>

function CopyItemById(listId, itemId, siteUrl) {   
    var ajaxRequestUrl = siteUrl + "/_layouts/15/CopyItem/CopyItem.ashx?listId=" + listId + "&itemId=" + itemId;
    $.ajax(ajaxRequestUrl)
       .done(
           function (copyResult)
           {
               if (!copyResult.ErrorMessage) {
                   var editUrl = GetSiteUrl() + copyResult.UpdateFormUrl + "?ID=" + copyResult.NewItemId + "&source=" + document.location.href;
                   openDialogForMeetingRecord(editUrl, ‘Update the copied item‘);
               }
               else {
                   console.error("Copy Item error:" + copyResult.ErrorMessage);
                   console.error("StackTrace:" + copyResult.ErrorDetail);
               }
           }
       )
       .fail(function (error) {
           errorCallBack(error);
       });
}
function openDialogForMeetingRecord(url, title) {
    var options = {
        url: url,
        title: title,
        dialogReturnValueCallback: CallBackfromDialog
    };
    SP.UI.ModalDialog.showModalDialog(options);
}

function CallBackfromDialog(dialogResult) {
    document.location.reload();
    /*if (dialogResult == 1) {
        // TBD：refresh the data        
    }
    else {
        // Do nothing
    }*/
}

function GetSiteUrl() {
    var port = "";
    if (document.location.port && document.location.port.lenght > 0) {
        port = ":" + document.location.port;
    }

    return document.location.protocol + ‘//‘ + document.location.host + port;
}
