How To Check Document Set In Document Library

In this blog, you will learn how to check if a Document Set already exists in Document Library, using JSOM.

Introduction

A Document Set is a group of related documents that can be created in one step and then managed as a single entity.

Source Code

$(document).ready(function() {
       getDocSet('Documents','Orders',success,logError);

    });


function getDocSet(listTitle,docSetName, success,error) {
    var context = SP.ClientContext.get_current();
    var list = context.get_web().get_lists().getByTitle(listTitle);
    var items = list.getItems(createGetDocSetQuery(docSetName));
    context.load(items);
    context.executeQueryAsync(
      function() {
         var docSetItem = (items.get_count() > 0 ? items.getItemAtIndex(0) : null);
         success(docSetItem);
      },
      error
    );


    function createGetDocSetQuery(docSetName)
    {
        var query = new SP.CamlQuery();
        var viewXml =
        "<View>" +
        "<Query>" +
           "<Where>" +
               "<And>" +
                   "<Eq>" +
                      "<FieldRef Name=\"FSObjType\"/>" +
                      "<Value Type=\"Integer\">1</Value>" +
                   "</Eq>" +
                   "<Eq>" +
                      "<FieldRef Name=\"FileLeafRef\" />" +
                      "<Value Type=\"Text\">" + docSetName + "</Value>" +
                   "</Eq>" +
               "</And>" +
           "</Where>" +
        "</Query>" +
        "<RowLimit>1</RowLimit>" +
        "</View>";
        query.set_viewXml(viewXml);
        return query;
    }
}

Activate Document Set Feature

We need to activate it before we can create or configure new Document Set content types.

• Go to the top-level site in the site collection for which you want to enable Document Sets.
  
• Go to Site Actions menu-->click Site Settings.
  
• Now, go to Site Collection Administration - Site collection features.
  
• Find Document Sets in the list, and then click Activate.

Add Document Set as a Content Type to your Document Library

• Go to Document Settings and change the Advanced Settings to: Allow management of content types
  
  
  
  
• Then, go to the Settings, add from existing site content types, and find the Document Set content type. Select Document Set and click Add:
  
  
  
  
• Go to your Document library and select New Document -> Document Set from the drop-down list.

That's it. I hope you liked this blog.
