I need to add a new item in a document library using JSOM. The document library also possesses custom columns.

I am able to upload file but unable to get proper method to add the custom column values to the library using JSOM.

Following is the code that I have used for updating:

function receivedBinary() {
  clientContext = new SP.ClientContext.get_current();
  parentList = clientContext.get_web().get_lists().getByTitle("Lib_MasterDataDetails");
  fileCreateInfo = new SP.FileCreationInformation();
  fileCreateInfo.set_content(new SP.Base64EncodedByteArray());
  var arr = convertDataURIToBinary(this.result);
  for (var i = 0; i < arr.length; ++i) {
  newFile = parentList.get_rootFolder().get_files().add(fileCreateInfo);
  clientContext.executeQueryAsync(function (newFile) {
  var myListItem = newFile.get_listItemAllFields();
  myListItem.set_item("ClientLegalName", "NewValue");
  clientContext.executeQueryAsync(function (sender, args) {
         console.log("Item updated");
     }, genericFailHandler);
  }, genericFailHandler);

You'll need to upload the file using the SP.FileCreationInformation object, you can write to the list item that corresponds to the file by calling <file>.get_listItemAllFields()

When you use get_listItemAllFields() you'll have a regular list item object that you can use get_item() and set_item() on.

Here is a complete example, you can paste the entire thing into your browser dev tools and run it, just sub the list name in var oList and the field name in myListItem.set_item("Note", "NewValue")

var clientContext = SP.ClientContext.get_current();
var oWebsite = clientContext.get_web();
var oList = oWebsite.get_lists().getByTitle("Documents");

var fileCreateInfo = new SP.FileCreationInformation();
fileCreateInfo.set_url("my new file.txt");
fileCreateInfo.set_content(new SP.Base64EncodedByteArray());
var fileContent = "The content of my new file";

for (var i = 0; i < fileContent.length; i++) {

var newFile = oList.get_rootFolder().get_files().add(fileCreateInfo);
var myListItem = newFile.get_listItemAllFields();
myListItem.set_item("Note", "NewValue")

clientContext.executeQueryAsync(function(sender, args) {
    // success on setting item values
    console.log("Item updated");
}, genericFailHandler);

function genericFailHandler(sender, args) { 

Edit: I've included a complete working snippet, substitute the string in fileContent for the actual contents of your file and you should be up and running; but this example will create a sample text file then modify one of its list item field values. You can also do this with a single call to executeQueryAsync, so I've updated my answer to show that too.

  • Hi John, Thanks for your reply,i have tried this already and it is not working in this way while we add an item to the document library. I can only be able to upload the file using SP.FileCreationInformation(), but cannot able to update the custom fields.

What you want is not easy to explain and long.

I recommend you to use REST API instead JSOM. JSOM can upload file up to 1.5M according MSDN.

As I say the solution is long and if you want to, you can visit this post, is in Spanish and written by me just a few minutes ago as an answer to your problem.

The function is a little long

function GuardarArchivosAcciones(archivo) {
    var getFile = getFileBuffer(archivo);
    getFile.done(function(arrayBuffer) {
        var doUpload = uploadDocumentAcciones(arrayBuffer, archivo.name);
        doUpload.done(function(file, status, xhr) {
            var getItem = getListItemDocument(file.d.ListItemAllFields.__deferred.uri);
            , status, xhr) {
                var doGetListItemEntityTypeFullName = getListItemEntityTypeFullNameAcciones();
                doGetListItemEntityTypeFullName.done(function(archivo, status, xhr) {
                    var itemMetadata = {
                            '__metadata': {
                                'type': archivo.d.ListItemEntityTypeFullName
                            'AccionId': (data)

                        url: listItem.d.__metadata.uri,
                        data: JSON.stringify(itemMetadata),
                        type: 'POST',
                        contentType: 'application/json;odata=verbose',
                        headers: {
                            'X-HTTP-Method': 'MERGE',
                            'X-RequestDigest': $("#__REQUESTDIGEST").val(),
                            'Accept': 'application/json;odata=verbose',
                            'IF-MATCH': '*'
                        success: function(item) { 
                            Alert('Documento subido exitosamente');
                        error: function(err) {
                            Alert('Falló la subida de los archivos');
                        complete: function(item) { }

Upload files REST


Try this code.

byte[] content = Encoding.Unicode.GetBytes("file_content");

ClientContext ctx = new ClientContext(new Uri("http://your_site/"));
List l = ctx.Web.Lists.GetByTitle("Shared Documents");

File f = l.RootFolder.Files.Add(
       new FileCreationInformation() { Url = "File.aspx", Overwrite = true, Content = content }

ListItem item = f.ListItemAllFields;
item["ContentType"] = "Basic Page";
