each ajax is defined as an object because there are more ajax queries in the page and $. When (), is used. For example,

var a1 = $.post({
        url : "/report/A/rank/1",
        data: p1,
        contentType:"application/json;charset=UTF-8",
        dataType : "json",
        success : function(data, textStatus, jqXHR) {}
    });
var a2 = $.post({
        url : "/report/A/rank/2",
        data: p1,
        contentType:"application/json;charset=UTF-8",
        dataType : "json",
        success : function(data, textStatus, jqXHR) {}
    });
$.when(a1, a2).done(function(r1, r2) {
//
});

now, due to some other requirements, I want to dynamically reload a1Maga2 and $.when (a1Magina2), and change the incoming parameter to p2.

alternative: encapsulate the code of the three objects into a function for processing. However, as there are already many ajax on the page and are encapsulated by function, if you encapsulate the code again on this basis, it will affect the readability of the code. Is there a simple way to call it?
