我正在尝试获取一个按钮来存储按钮值（id answer0，'value2'）以及下拉框选择（id answer1，'value'。由于代码没有保存，尽管我已经设法在以前的尝试中保存按钮“value2”。谷歌搜索了 3 天无济于事。任何建议将不胜感激！

    $('.btn-answer').off('click').on('click', function(evt) {
        var answer0 = $(evt.target).attr("value2");
      //var answer1 = $("#answer1").val();
        var answer1 =$('#answer1 option:selected').text();
        var all_answers = {};
            all_answers['answer0'] = answer0;
            all_answers['answer1'] = answer1;
      if (typeof all_answers != 'undefined') {
        console.log(answer0);
        console.log(answer1);
        pybossa.saveTask(task.id, all_answers).done(function() {
                deferred.resolve();






<div>
            <select name="answer1" class = "btn-success btn-mini">
                <option value="none">Choose a Class</option>
                <option>Woodland and Scrub</option>
                        <option value="A1">Woodland</option>

                        ......
                        <option value="J5">Other Habitat</option>
                        </select>
                </div>




    <h1 id="question2"></h1> <!-- The question will be loaded here -->
    <h2><i class="icon-asterisk"></i> </h2>       
    <div id="answer0">             <!-- Start DIV for the submission buttons -->
        <!-- If the user clicks this button, the saved answer will be value2="Certai-->
        <button class="btn btn-success btn-answer" value2 ="a"><i class="icon icon-white icon-thumbs-up"></i> Certain</button>
        <!-- If the user clicks this button, the saved answer will be value2="Fairly Certain"-->
        <button class="btn btn-answer btn-warning" value2="b"><i class=""></i> Fairly Certain</button>
        <!-- If the user clicks this button, the saved answer will be value2="Fairly Certain"-->
        <button class="btn btn-answer btn-danger" value2="c"><i class="icon icon-white icon-thumbs-down"></i> Unsure</button>
    </div>
    <P></P>
    <!-- End of DIV for the submission buttons -->

更改此行：

var selected_answer1 = $("#answer1").val();

我猜$("#answer1")是input，和$("#answer1").val("value")你一起试图设定它的价值。但是你想获得它的价值。

从下拉列表中获取价值：

$('#id_of_drop_down').val();将返回值，而不是文本。

如果您想要 selected 的文本option，请使用：

$('#id_of_drop_down option:selected').text();.
