I use JSOM to upload document in library. I use this JS:

var file;
var fileCreateInfo;
function CreateFile()
    // Ensure the HTML5 FileReader API is supported
    if (window.FileReader)
        input = document.getElementById("fileinput");
        if (input)
            file = input.files[0];
            fr = new FileReader();
            fr.onload = receivedBinary;
        alert("The HTML5 FileSystem APIs are not fully supported in this browser.");

// Callback function for onload event of FileReader
function receivedBinary()

    var clientContext = new SP.ClientContext('http://pk-sp:88//');
    this.oWebsite = clientContext.get_web();
    var list = this.oWebsite.get_lists().getByTitle("Documents"); 

    fileCreateInfo = new SP.FileCreationInformation();
    fileCreateInfo.set_content(new SP.Base64EncodedByteArray());

    // Read the binary contents of the base 64 data URL into a Uint8Array
    // Append the contents of this array to the SP.FileCreationInformation
    var arr = convertDataURIToBinary(this.result);
    for (var i = 0; i < arr.length; ++i)

    // Upload the file to the root folder of the document library
    this.newFile = list.get_rootFolder().get_files().add(fileCreateInfo);

    clientContext.executeQueryAsync(onSuccess, onFailure);

function onSuccess()
    // File successfully uploaded

function onFailure()
    // Error occurred
    alert("Request failed: " + arguments[1].get_message());
    console.log("Request failed: " + arguments[1].get_message());

// Utility function to remove base64 URL prefix and store base64-encoded string in a Uint8Array
// Courtesy: https://gist.github.com/borismus/1032746
function convertDataURIToBinary(dataURI)
    var BASE64_MARKER = ';base64,';
    var base64Index = dataURI.indexOf(BASE64_MARKER) + BASE64_MARKER.length;
    var base64 = dataURI.substring(base64Index);
    var raw = window.atob(base64);
    var rawLength = raw.length;
    var array = new Uint8Array(new ArrayBuffer(rawLength));

    for (i = 0; i < rawLength; i++)
        array[i] = raw.charCodeAt(i);
    return array;

How can i get Id of uploaded file?

I can use SPServices library to get last id or find by Title. But I think that the best way to get this ID from the fileCreateInfo object. Is that possible?



You can get the ID from newFile, check out SP.File.listItemAllFields

You'll need to include the property in your load:

clientContext.load(newFile, 'ListItemAllFields');

Then you can access the ID with:

  • 1
