示例1: GetProperty
/// <summary> Gets an indexed property from an object or any object in its prototype chain.
/// <p>
/// Searches the prototype chain for a property with integral index
/// <code>index</code>. Note that if you wish to look for properties with numerical
/// but non-integral indicies, you should use getProperty(Scriptable,String) with
/// the string value of the index.
/// <p>
/// </summary>
/// <param name="obj">a JavaScript object
/// </param>
/// <param name="index">an integral index
/// </param>
/// <returns> the value of a property with index <code>index</code> found in
/// <code>obj</code> or any object in its prototype chain, or
/// <code>Scriptable.NOT_FOUND</code> if not found
/// </returns>
