嵌套的AJAX调用不起作用

I'm having trouble getting a nested AJAX call to work properly. All I want is to have the inner AJAX call executed if and after the outer AJAX call completed successfully.

var diningHours = $("#diningHours");
var facStaffDiningData = $("#facStaffDiningData");
var diningCommonsData = $("#diningCommonsData");
if($.trim(diningHours.html()).length == 0) {
    var season;
    //This call executes fine (tested it with console logging)
    $.get("data/dining-hours.php", {summer: "check"}, function(seasonData, seasonStatus) {
        if(seasonStatus == "success") {
            season = seasonData;
            //This is the call that isn't being executed
            $.get("data/dining-hours.php", function(hoursData, hoursStatus) {
                if(hoursStatus == "success") {
                    var hours = $(hoursData).find("hours dining");
                    var html = hoursFeed(hours, season);
                    diningHours.append(html).collapsibleset("refresh");
                }
            });
        }

    });
}

Am I doing something wrong?

I think seasonStatus is redundant, because the callback will be executed on success.

This should works

var season;
    //This call executes fine (tested it with console logging)
    $.get("data/dining-hours.php", {summer: "check"}, function(season, seasonStatus) {
           console.log('CB1',season);
            $.get("data/dining-hours.php", function(hoursData) {
                    console.log('CB2',hoursData);
                    var hours = $(hoursData).find("hours dining");
                    var html = hoursFeed(hours, season);
                    diningHours.append(html).collapsibleset("refresh");

            });
        }

    });

I'd try something like this:

var diningHours = $("#diningHours"),
    facStaffDiningData = $("#facStaffDiningData"),
    diningCommonsData = $("#diningCommonsData");

if(!$.trim(diningHours.html()).length) {
    var XHR = $.get("data/dining-hours.php", {summer: "check"});
        XHR.success(function(seasonData) {
            var season = seasonData,
                XHR2 = $.get("data/dining-hours.php");
                XHR2.success(function(hoursData) {
                    var hours = $(hoursData).find("hours dining"),
                        html = hoursFeed(hours, season);
                    diningHours.append(html).collapsibleset("refresh");
                });
        });
}​

The question is, what exactly is hours dining, and how do you expect the find() function to find it ?

Digging deeper into the issue I found the true source of my problem. The XML document had a bunch of encoding errors (there were things like reserved and copyright symbols in with the data). Removing these and replacing them with the correct entities fixed the problem. My original code that I thought was the issue now works perfectly fine.
