In this example i am trying to retrieve Account entity information in form load script using ODATA and JSON in CRM 2011
To use ODATA service you need two resource files
JSON and JQuery
you can download these popular resource in web...
Now write following java script in the new web resource file
function init()
{
// write required ODATA query
var odataSelect = "http://server/orgname/XRMServices/2011/OrganizationData.svc/AccountSet(guid'6C2EFF37-BD39-E011-91D1-000C2971AF13')";
$.ajax({
type: "GET",
contentType: "application/json; charset=utf-8",
datatype: "json",
url: odataSelect,
beforeSend: function (XMLHttpRequest) { XMLHttpRequest.setRequestHeader("Accept", "application/json"); },
success: function (data, textStatus, XmlHttpRequest)
{
// Use this method for a selection that return single entitie
RetrieveEntityData(data.d);
// Use this method for a selection that may return multiple entities
RetrieveMultipleEntities(data.d.results);
},
error: function (XmlHttpRequest, textStatus, errorThrown) { alert('OData Select Failed: ' + odataSelect); }
});
}
function RetrieveEntityData(Entity)
{
// get the fields from the Entity object
var accountNumber = Entity.AccountNumber;
var AccountName = Entity.Name;
alert(Entity.Name);
}
function RetrieveMultipleEntities(ManyEntities)
{
for( i=0; i< ManyEntities.length; i++)
{
// get the fields from the Entity object
var Entity = ManyEntities[i];
var accountNumberAttribute = Entity.AccountId;
var AccountName = Entity.Name;
alert(Entity.Name);
}
}
Just call the init method from the CRM form events, but make sure you have to add JSON and JQuery web resources to the event library before adding this web resource. It has to follow the sequence JSON,JQuery and Custom web Resource.
To get the Required entity ODATA set use the following url
