Hi there I was using the sdk 2013 Odata Sample
retrieveMultipleRecords: function (type, options, successCallback, errorCallback, OnComplete) {
///<summary>
/// Sends an asynchronous request to retrieve records.
///</summary>
///<param name="type" type="String">
/// The Schema Name of the Entity type record to retrieve.
/// For an Account record, use "Account"
///</param>
///<param name="options" type="String">
/// A String representing the OData System Query Options to control the data returned
///</param>
///<param name="successCallback" type="Function">
/// The function that will be passed through and be called for each page of records returned.
/// Each page is 50 records. If you expect that more than one page of records will be returned,
/// this function should loop through the results and push the records into an array outside of the function.
/// Use the OnComplete event handler to know when all the records have been processed.
/// </param>
///<param name="errorCallback" type="Function">
/// The function that will be passed through and be called by a failed response.
/// This function must accept an Error object as a parameter.
/// </param>
///<param name="OnComplete" type="Function">
/// The function that will be called when all the requested records have been returned.
/// No parameters are passed to this function.
/// </param>
this._stringParameterCheck(type, "SDK.REST.retrieveMultipleRecords requires the type parameter is a string.");
if (options != null)
this._stringParameterCheck(options, "SDK.REST.retrieveMultipleRecords requires the options parameter is a string.");
this._callbackParameterCheck(successCallback, "SDK.REST.retrieveMultipleRecords requires the successCallback parameter is a function.");
this._callbackParameterCheck(errorCallback, "SDK.REST.retrieveMultipleRecords requires the errorCallback parameter is a function.");
this._callbackParameterCheck(OnComplete, "SDK.REST.retrieveMultipleRecords requires the OnComplete parameter is a function.");
var optionsString;
if (options != null) {
if (options.charAt(0) != "?") {
optionsString = "?" + options;
}
else
{ optionsString = options; }
}
var req = new XMLHttpRequest();
req.open("GET", this._ODataPath() + type + "Set" + optionsString, true);
req.setRequestHeader("Accept", "application/json");
req.setRequestHeader("Content-Type", "application/json; charset=utf-8");
req.onreadystatechange = function () {
if (this.readyState == 4 /* complete */) {
req.onreadystatechange = null;
if (this.status == 200) {
var returned = JSON.parse(this.responseText, SDK.REST._dateReviver).d;
successCallback(returned.results);
if (returned.__next != null) {
var queryOptions = returned.__next.substring((SDK.REST._ODataPath() + type + "Set").length);
SDK.REST.retrieveMultipleRecords(type, queryOptions, successCallback, errorCallback, OnComplete);
}
else
{ OnComplete(); }
}
else {
errorCallback(SDK.REST._errorHandler(this));
}
}
};
req.send();
},
what are the steps to use the above function for the following code to check for the existing phone
function ValidateContactInformation(econtext)
{
if(Xrm.Page.getAttribute("telephone1") != null)
{
if(Xrm.Page.getAttribute("telephone1").getValue() != null)
{
var mobileNumber = Xrm.Page.getAttribute("telephone1").getValue();
var serverUrl = Xrm.Page.context.getServerUrl();
var oDataEndpointUrl = serverUrl + "/XRMServices/2011/OrganizationData.svc/";
oDataEndpointUrl += "ContactSet?$select=Telephone1&$filter=Telephone1 eq '" + mobileNumber + "'";
var service = GetRequestObject();
if(service != null)
{
service.open("GET", oDataEndpointUrl, false);
service.setRequestHeader("X-Requested-Width", "XMLHttpRequest");
service.setRequestHeader("Accept", "application/json, text/javascript, */*");
service.send(null);
if (service.status != 200)
{
alert("Unable to get Bill To Information using OData Call. ");
return;
}
var requestResults = eval('(' + service.responseText + ')').d;
if(requestResults != null)
{
if(requestResults.results[0] != null)
{
alert("This Phone number is already exist please try to set another one. thanks");
econtext.getEventArgs().preventDefault();
//Xrm.Page.context.getEventArgs().preventDefault();
}
}
}
}
}
}
function GetRequestObject()
{
if (window.XMLHttpRequest)
{
return new window.XMLHttpRequest;
}
else
{
try
{
return new ActiveXObject("MSXML2.XMLHTTP.3.0");
}
catch (ex)
{
return null;
}
}
}
