  • Is it a cross-domain issue? What does your browser console window say?

    This could be the problem then. Can you deploy your Web Service under the Tridion IIS Website and therefore it would not be cross domain? Or, add CORS to the C# web service and also jQuery? I've lost a lot of time before with these cross domain issues and sometimes hosting it under the Tridion CMS website is the easiest.

  • robrtc do you have any links to call service form jquery code to web service into the tridion and its steps...i seen usually they are using GET Method of AJAX..to request server...every where they are registering name spaces

  • Another idea could be that your popup is a Web App (not .html with jQuery) and then you pass the WebApp the URIs of items you want to process, and use Core Service within the WebApp to do the work.

I would suggest not trying to use jQuery for this.

It is unnecessary as there is already a framework available that provides you with everything you need to call your web service model.

In fact, as soon as you configure the service in your model, a proxy JavaScript object is automatically created that allows you to call the web methods and handle success & failure. It is named the same as the fully qualified name of your web service, but with lowercase letters for the namespace.

The process for creating your own model is pretty simple and is documented on the following page (requires login): Creating a Data Model
