Update record using OData and JQuery in CRM 2011

The following function could be used to update records in json/ajax.This could be useful in scenario where we want to update some records in the background

function updateRecord(id, entityObject, odataSetName) {

    //debugger;

    var jsonEntity = window.JSON.stringify(entityObject);

    // Get Server URL

    var serverUrl = Xrm.Page.context.getServerUrl();

    //The OData end-point

    var ODATA_ENDPOINT = "/XRMServices/2011/OrganizationData.svc";

    //Asynchronous AJAX function to Update a CRM record using OData

    $.ajax({

        type: "POST",

        contentType: "application/json; charset=utf-8",

        datatype: "json",

        data: jsonEntity,

        url: serverUrl + ODATA_ENDPOINT + "/" + odataSetName + "(guid'" + id + "')",

        beforeSend: function (XMLHttpRequest) {

            //Specifying this header ensures that the results will be returned as JSON.

            XMLHttpRequest.setRequestHeader("Accept", "application/json");

            //Specify the HTTP method MERGE to update just the changes you are submitting.

            XMLHttpRequest.setRequestHeader("X-HTTP-Method", "MERGE");

        },

        success: function (data, textStatus, XmlHttpRequest) {

            //alert('Updated successfully');

        },

 

        error: function (XmlHttpRequest, textStatus, errorThrown) {

            if (XmlHttpRequest && XmlHttpRequest.responseText) {

                alert("Error while updating " + odataSetName + " ; Error – " + XmlHttpRequest.responseText);

            }

        }

    });

 

}

 

The above function can be called in the following manner, for eg. if I want to call this function to update a picklist/optionset value on the incident entity

var caseId = Xrm.Page.data.entity.getId();

var incidentObj = new Object();

incidentObj.fieldname_optionsettypeoffield = { Value: 1 };

updateRecord(caseId, incidentObj, "IncidentSet");

 

Note: This will require json2 and jquery1.4.1.min.js to be preloaded on your form as shown below
