To exchange data with the back-end that is often used in the front-end, ajax is usually used. This article mainly introduces various related knowledge of the front-end ajax and the back-end interaction, which has a good reference value. Let’s take a look with the editor below, I hope it can help everyone.
But there are many ways to interact, many of which depend on the properties of your backend. Here I will mainly list two methods that are commonly used in my current projects
--One is our common web api and controller,
First of all, let’s take a closer look at the interaction data between ajax and webapi
