调用控制器操作在BrowserControl中无法按预期工作

Question

我有一个MVC应用程序，包括电子学习材料和每门课程的相关调查。我的调查是为了点击下一个按钮而调用课程控制器和GoForward方法，就像在Course / GoForward中一样，它在所有浏览器中运行良好。然而，当尝试将其连接到我们的遗留软件时，在浏览器控件中向用户显示内容时，我无法在第二个问题上单击下一个，这似乎只是停滞不前。是否有任何阻止BrowserControl在我的课程控制器上调用POST操作的东西。这是第一个问题的第一个问题，并成功地显示我的问题出现的第二个问题。我的代码如下：

if (questionType == 'Multiple Choice') {
        var multiChoice = document.getElementsByName("radio");
        var hasAnswer = 0;
        for (var i = 0; i < multiChoice.length; i++) {
            //If the radio button is checked submit the answer
            if (multiChoice[i].checked) {
                hasAnswer = 1;
                var id = multiChoice[i].id;
                var splitID = id.split(" ");
                var surveyID = $('#surveyID').text();
                var questionID = splitID[0];
                var answerID = splitID[1];
                var comment = document.getElementById(questionID + " Comment");
                if (comment != null) {
                    comment = comment.value;
                }

                var postData = {
                    'surveyID': surveyID,
                    'questionID': questionID,
                    'answerID': answerID,
                    'answerText': null,
                    'comment': comment,
                    'questionType': questionType
                };
                if (button == "Next") {
                    $.post('/Course/GoForward/', postData, function (data) {
                        $('#SurveyDiv').html(data);
                    });
                }
                if (button == "Previous") {
                    $.post('/Course/GoBackward/', postData, function (data) {
                        $('#SurveyDiv').html(data);
                    });
                }
                if (button == "Submit") {
                    $.post('/Course/SurveyComplete/', postData, function (data) {
                        $('#SurveyDiv').html(data);
                        //$('#surveyDiv').hide();
                        var surveyID = $('#surveyID').text();

                        var postData = {
                            'surveyID': surveyID
                        };

                        $.post('/Course/SurveyAnswers/', postData, function (data) {                               
                        });
                    });
                }
            }

            //If there are no selected answers at the end of the for loop
            if (i == multiChoice.length - 1 && hasAnswer == 0) {
                //Check if the question requires an answer
                if (requiresAnswer == 1) {
                    $('#validationNoAnswer').show();
                }
                //else submit empty answer
                else {
                    var id = multiChoice[0].id;
                    var splitID = id.split(" ");
                    var surveyID = $('#surveyID').text();
                    var questionID = splitID[0];

                    var comment = document.getElementById(questionID + " Comment");
                    if (comment != null) {
                        comment = comment.value;
                    }

                        'questionType': questionType
                    };

                    if (button == "Next") {
                        $.post('/Course/GoForward/', postData, function (data) {
