Retrieve Option Set text from CRM 2011/2013/2015 in JavaScript

Hi,
 
Today I got a requirement to write JavaScript code to get text of the option set value and perform some business validations.
 
Its really pretty simple to get the option set text from the particular entity and attribute.
 
We just need to add SDK.Metadata.js reference. This can found under (SDK\SampleCode\JS\SOAPForJScript\SOAPForJScript\Scripts) and use the below code.

function GetOptionSetText(EntityLogicalName, AttributeLogicalName) {

    SDK.Metadata.RetrieveAttribute(EntityLogicalName, AttributeLogicalName, "00000000-0000-0000-0000-000000000000", true,
       function (result) {
            for (var i = 0; i < result.OptionSet.Options.length; i++) {
                var text = result.OptionSet.Options[i].Label.LocalizedLabels[0].Label;
                var value = result.OptionSet.Options[i].Value;
            }
        },
        function (error) { }
    );
}

Hope this helps.
