Question

我希望有人能帮助我用javascript解决这个小问题。我确实创建了一个javascript函数，根据用户从选择框中选择的值自动呈现2种不同的表单。用户单击按钮时会触发该功能。问题是不会生成表单而是收到错误消息：＆＃34;未捕获的ReferenceError：未定义addFields＆＃34;。

Html代码：

<div class="form-group " style="margin-left: 80%">

                                    <div class="col-sm-10">
                                        <button type="button" class="btn btn-success btn-lg" onclick="addFields()">Formular erstellen</button>
                                    </div>
                                </div>

Javascript代码：

<script type="text/javascript">
        function addFields() {
            // Number of inputs to create
            var number = document.getElementById("anzahlFragen").value;
            // Type of Quiz
            var type = document.getElementById("quizTyp");
            var selectedType = type.options[type.selectedIndex].text;
            // Container <div> where dynamic content will be placed
            var myContainer = document.getElementById("myContainer");
            // Clear previous contents of the container
            while (myContainer.hasChildNodes()) {
                myContainer.removeChild(myContainer.lastChild);
            }
            if (selectedType === "Multiple choices") {

Answer 1

您已在变量声明optionT1，optionT2，optionT3和optionT4上方的行末尾放置逗号而不是分号。
