使用JQuery获取TextArea

Question

我正在使用JQuery提交表单.表格如下所示

<form class="ask-more-form">
<div class="product_info_2">
<textarea name="product_question" class="textbox" placeholder="Ask You Question Here"></textarea>
</div>
<input type="hidden" name="product_id" value="1" id="product_id">
<a href="#" class="whiteButton submit" id="ask-more-submit-button">Ask Question</a>
</form>

并且用于捕获表单的JQuery看起来像这样:

$('#ask-more').on('submit', '.ask-more-form', function() {
        var product_id = $(this).children('input[name=product_id]').val();
        var product_question = $(this).children('textarea[name="product_question"]').text();

alert(product_question);
//submitQuestion(product_id, product_question);

                });

始终读取product_id,但产品问题始终为null.谁能告诉我为什么会这样？

.children 只下降一级..find改为使用:

$('#ask-more').on('submit', '.ask-more-form', function () {
    var product_id = $(this).children('input[name=product_id]').val();
    var product_question = $(this).find('textarea[name="product_question"]').text();
    alert(product_question);
    //submitQuestion(product_id, product_question);
});
