I have one button on clicking I need multiple things need to be done, so I went for AJAX and PHP:

$('.go_nxt_lsn').live('click',function(e){
    e.stopPropagation();
    var user_id = $('input[name=user_id]').val();
    var course_id = $('input[name=course_id]').val();
    var taskName = "SaveActivity";
    var subTask = "watchvideo";
    var lesson_id = $(this).attr('data-lesson-id');
    var video_id = $(this).attr('data-video-id');
    var course_box = '.course_'+course_id;
    var refresh_boo = 1;

    $.ajax({
        type        : 'POST', 
        url         : 'url']?>learn/pages/syllabus/saveitems.php',
        datatype    : 'html',
        data        : {subtask:subTask,lessonid:lesson_id,theSubModID:video_id,userid:user_id,prodid:course_id,taskname:taskName},
        success:function(data)
        {
            taskName = "GoToNextLesson"
            $.ajax({
                type        : 'POST', 
                url         : 'url']?>learn/pages/syllabus/saveitems.php',
                datatype    : 'html',
                data        : {subtask:subTask,lessonid:lesson_id,userid:user_id,prodid:course_id,taskname:taskName},
                success:function(data)
                {   
                    $.ajax({
                        type        : 'POST', 
                        url         : 'url']?>learn/pages/syllabus/learn.php',
                        datatype    : 'json',
                        data        : {user_id:user_id,course_id:course_id},

                        {
                            $.ajax({
                                type        : 'POST', 
                                url         : 'url']?>mod/event_calendar/views/default/event_calendar/instantlearn.php',

The chain of Ajax calls can be set programmatically, instead of being "hardcoded" as in your code. The next snippet shows a possible approach.

However, as Piotr pointed out, you should study your application a bit more to determine whether that is a good solution.

// First generate an array with all the ajax calls than need to be done, in order.
var ajaxCalls = [

    // First ajax
    function(){
        return $.ajax({
            type        : 'POST', 
            url         : 'url']?>learn/pages/syllabus/saveitems.php',
            datatype    : 'html',
            data        : {subtask:subTask,lessonid:lesson_id,theSubModID:video_id,userid:user_id,prodid:course_id,taskname:taskName}
        });
    },

    // Second ajax
    function(data){
        return $.ajax({
            type        : 'POST', 
            url         : 'url']?>learn/pages/syllabus/saveitems.php',
            datatype    : 'html',
            data        : {subtask:subTask,lessonid:lesson_id,userid:user_id,prodid:course_id,taskname:taskName}
        });
    },

    ...

    // Last function doesn't need to return a promise
    function(data){
        $(course_box).replaceWith(data);
        $(".accordion").accordion({     
            active: false, 
            collapsible: true,
            heightStyle: "content"
        });
    }
];
