Create a Ajax call to a controller function with your parameter individually like
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "Controller/ActionMethod",
data: "{ STVal: '247', Name : 'abc', Cat : 'general' }",
dataType: "json",
success: function(response) { alert("item added"); },
error: function(xhr, ajaxOptions, thrownError) { alert(xhr.responseText); }
});
Receive the values in the Action Method and pass to a view like,
[HttpPost]
public ActionResult ActionMethod(string STVal, string Name, string Cat )
{
// your code
return view();
}
