Detailed explanation of the steps to call WCF service with jQuery+ajax

This time I will bring you a detailed explanation of the steps for jQuery ajax to call WCF services. What are the precautions for jQuery ajax to call WCF services? The following is a practical case, let's take a look.

The example in this article describes how jQuery implements ajax to call WCF services. Share it with everyone for your reference, the details are as follows:

Regarding AJAX calling WCF services, there are two methods: cross-domain and non-cross-domain. Today we will first introduce the non-cross-domain calling method. DEMO was written in VS2008.

After testing and research, it was found that AJAX calling WCF service must meet the following conditions

1. The communication method of wcf must use webHttpBinding

2. Must set < ;endpointBehaviors>The value of the node
3. The implementation of the service must add the mark

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]

4. The following mark must be added in front of the method

[WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Json)]

5. The parameter name passed in the ajax method must be the same as The parameter method names provided in the wcf service are the same

The following is the code I wrote, the colors marked are the places that need attention
