javascript - jQuery AJAX 未输入 "success"

Question

$(function(){
    $(document).ready(function(){
        $.ajax({
            url: "src/cookiecheck.php",
            type: "POST",
            async: true,
            success: function(json){
                if(json.visitedBefore!="true"){
                    $("#cookiepolicy").fadeIn();
                }
            }
        });
        window.alert(5);
        $.ajax({
            url: "src/lessons.php",
            type: "POST",
            async: true,
            success: function(json){
                window.alert(1);
            }
        });
    });
});

这是我的应用程序的 jQuery 部分，它成功执行第一个 ajax 调用并显示“window.alert(5);”中的 5。进行了第二次调用，但由于某种原因未触发成功。以下是“lessons.php”的输出:

{"ID":"5"}
{"Name":["111","2","3","4","5","123123"]}
{"Location":["1112","2","3","4","5","3123123"]}

Answer 1

这不是有效的 json:

{"ID":"5"}
{"Name":["111","2","3","4","5","123123"]}
{"Location":["1112","2","3","4","5","3123123"]}

也许可以这样格式化:

{
"things": {"ID":"5"},
"names": {"Name":["111","2","3","4","5","123123"]},
"locations": {"Location":["1112","2","3","4","5","3123123"]}
}
