在通过ODdata方式获取CRM数据时，默认查询出来的results只有50条数据，可以通过JSON返回的Object中的“_next”属性作为URL循环获取直到该属性为空

示例代码如下：

relatedAccounts = [];

function onload() {

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

    var oDataUri = serverUrl + "/xrmservices/2011/OrganizationData.svc/AccountSet?$select=AccountId,Name,&$filter=StateCode/Value eq 0";

    GetRecords(oDataUri);

    var totalRecords = relatedAccounts.length;

}

function GetRecords(url) {

    jQuery.ajax({

        type: "GET",

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

        datatype: "json",

        url: url,

        async: false,

        beforeSend: function (XMLHttpRequest) {

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

        },

        success: function (data, textStatus, XmlHttpRequest) {

            if (data && data.d != null && data.d.results != null) {

                AddRecordsToArray(data.d.results);

                FetchRecordsCallBack(data.d);

            }

        },

        error: function (XmlHttpRequest, textStatus, errorThrown) {

            alert("Error :  has occured during retrieval of the records ");

        }

    });

}

function AddRecordsToArray(records) {

    for (var i = 0; i < records.length; i++) {

        relatedAccounts.push(records[i]);

    }

}

function FetchRecordsCallBack(records) {

    if (records.__next != null) {

        var url = records.__next;

        GetRecords(url);

    }

}
