Beginning Web Development, Silverlight, and ASP.NET AJAX

CHAPTER 12 ■ AJAX EXTENSIONS FOR ASP.NET 303
Figure 12-19. Accessing the JavaScript proxy
This proxy file will look something like this:
var DataService=function() {
DataService.initializeBase(this);
this._timeout = 0;
this._userContext = null;
this._succeeded = null;
this._failed = null;
}
DataService.prototype={
GetCountryForRegion:function(
strRegion,succeededCallback, failedCallback, userContext)
{
return this._invoke(DataService.get_path(),
'GetCountryForRegion',false,{strRegion:strRegion},
succeededCallback,failedCallback,userContext); }}
DataService.registerClass('DataService',Sys.Net.WebServiceProxy);
DataService._staticInstance = new DataService();
DataService.set_path = function(value)
{ DataService._staticInstance._path = value; }
DataService.get_path = function()
{ return DataService._staticInstance._path; }
DataService.set_timeout = function(value)
{ DataService._staticInstance._timeout = value; }
