使用 Javascript 以编程方式访问共享点中文档集中的文件

Question

我想访问文档库中特定文档集中的文件。

到目前为止，我能够使用 JSOM 获取特定的文档集名称和 ID，如下所示。如何读取文档集中的所有文件

<script type="text/javascript" src="//ajax.aspnetcdn.com/ajax/4.0/1/MicrosoftAjax.js"></script>
<script type="text/javascript" src="_layouts/15/sp.runtime.js"></script>
<script type="text/javascript" src="_layouts/15/sp.js"></script>
 
<script type="text/javascript">
   ExecuteOrDelayUntilScriptLoaded(MainFunction, "sp.js");
 
    function MainFunction() {
        var clientContext = new SP.ClientContext.get_current();
        var oList = clientContext.get_web().get_lists().getByTitle('Planner Session');
 
        var camlQuery = new SP.CamlQuery(); //initiate the query object
 
        camlQuery.set_viewXml('<View><Query><Where><Lt><FieldRef Name="ID" /><Value Type="Counter">3</Value></Lt></Where><OrderBy><FieldRef Name="ID" Ascending="FALSE"/></OrderBy></Query><RowLimit>1</RowLimit></View>');
 
        this.collListItem = oList.getItems(camlQuery);
 
        clientContext.load(collListItem);
        clientContext.executeQueryAsync(
            Function.createDelegate(this, this.onQuerySucceeded),
            Function.createDelegate(this, this.onQueryFailed)
        );
    }
 
    function onQuerySucceeded(sender, args) {
        var DocSet = "";
        var listItemEnum = collListItem.getEnumerator();
 
        while (listItemEnum.moveNext()) {
            var oListItem = listItemEnum.get_current();
            DocSet += '\n\nID: ' + oListItem.get_id() + '\nName: ' + oListItem.get_item('FileLeafRef');
        }
 // Here i would like to get the file inside the documentSet 
        alert(DocSet.toString());
    }
 
    function onQueryFailed(sender, args) {
        alert('Request failed. ' + args.get_message() +
            '\n' + args.get_stackTrace());
    }
</script>
 
<input type="button" value="Get Products" onclick="MainFunction()"/>

如何通过 SharePoint CSOM 获取文档集的文件

假设结构如下：

Documents (library)
    |
    2013 (Document set)

基于查询的方法

以下示例演示如何使用 CAML query return 位于文档集中的文件：

function getListItems(listTitle,folderUrl,success,error)
{
   var ctx = SP.ClientContext.get_current();
   var web = ctx.get_web();
   var list = web.get_lists().getByTitle(listTitle);
   var qry = SP.CamlQuery.createAllItemsQuery();
   qry.set_folderServerRelativeUrl(folderUrl);
   var items = list.getItems(qry);
   ctx.load(items,'Include(File)');
   ctx.executeQueryAsync(
      function() {
          success(items); 
      },
      error);
}

要点：

SP.CamlQuery.folderServerRelativeUrl property习惯于return 仅位于特定 url

用法

var listTitle = 'Documents';
var docSetUrl = '/Documents/2013';  
getListItems(listTitle,docSetUrl, 
     function(items){
        for(var i = 0; i < items.get_count();i++) {
            var file = items.get_item(i).get_file();
            console.log(file.get_title());
        }
     },
     function logError(sender,args) 
     {
        console.log(args.get_message());
     });

使用SP.Web.getFolderByServerRelativeUrl方法

使用SP.Web.getFolderByServerRelativeUrl Method to get Document Set object located at the specified server-relative URL and then SP.Folder.files property获取文档集中包含的所有文件的集合

完整示例：

function getFiles(folderUrl,success,error)
{
    var ctx = SP.ClientContext.get_current();
    var files = ctx.get_web().getFolderByServerRelativeUrl(folderUrl).get_files();
    ctx.load(files);
    ctx.executeQueryAsync(
      function() {
          success(files); 
      },
      error);
}

用法

var docSetUrl = '/Documents/2013';  //<-- '2013'
getFiles(docSetUrl, 
     function(files){
        for(var i = 0; i < files.get_count();i++) {
            var file = files.get_item(i);
            console.log(file.get_title());
        }
     },
     function logError(sender,args) 
     {
        console.log(args.get_message());
     });

请找到执行以下操作的完整代码 1.根据我的条件获取需要的docset 2. 通过检查自定义列

中的值获取该特定文档集中的所有文件
