Cross domain javascript function call. That policy is called cors. Let s move on to the next way of making cross domain ajax possible. Like cors the server has to support jsonp.

Call wcf service by using jquery jquery already has support to handle the jsonp. Name it as. After the javascript library is referenced a page level javascript is called in the html body load event.

There are two solutions to call the cross domain wcf service. Basically the client tells the server the callback function for the response. Steps to make asp net web api service.

We ll look at how to set up cors on the server in php how to make the request in javascript and some considerations. Since the data is wrapped in a javascript function this can be consumed by a web page that is present in a different domain. To prove browsers do not allow cross domain ajax calls let s create a new asp net mvc application.

Cors as a concept is broader than just ajax requests but this is it s main use. Cross origin requests those sent to another domain even a subdomain or protocol or port require special headers from the remote side. Jquery library provided function ajax and getjson which can allow to call the wcf service which sends jsonp data in response.

Cross origin resource sharing or cors can be used to make ajax requests to another domain.
