Using REST API to upload Multiple  Files to Sharepoint  Document library

 The code I’m going to show you how you can upload multiple  files to  document library using REST

............................................................................................................................................

<div class="div">
<input id="getFile" multiple="multiple" type="file"/>
<input id="addFileButton" type="button" value="Upload" onclick="uploadnewfile()"/> 
</div>

..............................................................................................................................................

function uploadnewfile() {

// Define the folder path for this example.

var serverRelativeUrlToFolder = 'Resume';

// Get test values from the file input and text input page controls.

　
var fileInput = $('#getFile');

var fileName = fileInput[0].files[0].name;

var fileCount = fileInput[0].files.length;


// Get the server URL.

var serverUrl = _spPageContextInfo.webAbsoluteUrl;

var filesUploaded = 0;

for (var i = 0; i < fileCount; i++) {



// Get the local file as an array buffer.

var getFile = getFileBuffer(i);

getFile.done(function (arrayBuffer, i) {

// Add the file to the SharePoint folder.

var addFile = addFileToFolder(arrayBuffer, i);

addFile.done(function (file, status, xhr) {


filesUploaded++;
if (fileCount == filesUploaded) {

alert("All files uploaded successfully");

                   

$("#getFile").value = null;

filesUploaded = 0;
}
});
addFile.fail(onError);
});
getFile.fail(onError);
}
// Get the local file as an array buffer.

function getFileBuffer(i) {

var reader = new FileReader();

reader.onloadend = function (e) {

deferred.resolve(e.target.result, i);

var index = i;

"{0}/_api/web/getfolderbyserverrelativeurl('{1}')/files" +

"/add(overwrite=true, url='{2}')",

serverUrl, serverRelativeUrlToFolder, fileName);
// Send the request and return the response.

// This call returns the SharePoint file.

return jQuery.ajax({
