The following examples are used to illustrate, first look at Action

[HttpPost] public ActionResult Test(List model) { return Json(null, JsonRequestBehavior.AllowGet); }

Debug mode monitoring parameters, when the button is clicked, the monitored parameters are as follows

Method 2: Use JavaScript objects as parameters to pass values. The parameter name is the parameter name corresponding to the Action method, and the parameter value is a JavaScript array
