<script language="javascript" type="text/javascript">  
$(document).ready(function(){

    $("#Button1").click(function(){  

                updateMetadata(1);
    });
});           


function updateMetadata(id) {
alert('buttonIn'+id);
    var url = _spPageContextInfo.webAbsoluteUrl +"/_api/Web/Lists/getByTitle('MyDocuments')/Items(" + id + ")";

    alert(url);

    var dfd = $.Deferred();

    $.ajax(

    {

        'url': url,

        'method': 'POST',

        'data': JSON.stringify({

            '__metadata': {'type':'SP.MyDocumentsListItem'},

            'Title': 'Update Field Again'

        }),

        'headers': {

            'accept': 'application/json;odata=verbose',

            'content-type': 'application/json;odata=verbose',

            'X-RequestDigest': $('#__REQUESTDIGEST').val(),

            'X-Http-Method': 'MERGE',

            "If-Match": "*"

        },

        'success': function (data) {
alert('updated'+data);
            var d = data;

            dfd.resolve();

        },

        'error': function (err) {
alert(err);
            dfd.reject();

Try using "Patch" instead of "Merge":

'X-Http-Method': 'PATCH'
  • Hi Alok, Thank you for your quick response. but it is not working for both PATCH and MERGE. same time its not giving any error also. i have placed an alert in Success method it is prompting as well. – rajendar Apr 10 '17 at 6:18
  • Hi Rajendar, pls check deferred implementation as per link sharepointempower.com/Lists/Posts/Post.aspx?ID=22 – Alok Kumar Gupta Apr 10 '17 at 7:37

 '__metadata': {'type':'SP.MyDocumentsListItem'},

if your library name is MyDocuments that should be

 '__metadata': {'type':'SP.MyDocumentsItem'},
  • No luck. this one also not resolved my issue. still not updating the item. – rajendar Apr 10 '17 at 9:13
  • Just to rule this out, if you open /_api/Web/Lists/getByTitle('MyDocuments')/Items in the browser you should get a bunch of xml code. The item type is in there like this <category term="SP.Data.Shared_x0020_DocumentsItem" ... In this example the name of the library is just documents, so it's not necessarily derived from the current library name – JJD Apr 11 '17 at 6:55
