                       ]}
               ]}
       ]},
       {"courseStarted" :[
               {"CategoryName":"CategoryName","courseName" :"Equipment Course1", "seriesName": "Free Education1", "courseDetails" :[
                       {"totalLessons" :"21", "NoLessonComplete":"11", "lastviewed":"date1", "lessonDetails":[
                               {"lessonId":"3423671","quiz":"quizReady"},
                               {"lessonId" :"3453451", "quiz":"quizReady"},
                               {"lessonId":"4354351","quiz":"quizReady"},
                               {"lessonId":"42342341", "quiz":"quizReady"},
                               {"lessonId":"42342341","quiz":"quizPassed"}
                       ]}
               ]}
       ]}

    ]

从此 json 输出中，我如何使用 $.each 函数访问 courseId 的值。

Answer 1

$.each(data, function(){

    // Print course name
    console.log(this.courseStarted[0].courseName);

    $.each(this.courseStarted[0].courseDetails[0].lessonDetails, function(){
        // Print lesson id
        console.log(this.lessonId);
    });

});
