javascript - 使用 Jquery .find() 遍历按类选择元素并存储 Prop

Question

我正在尝试使用以下代码搜索元素“service-block”的后代以查找具有类“title”的特定元素。除了“未定义”之外，我无法让 var 分配任何东西。任何帮助将不胜感激 -

<div class="col-md-4">
        <div id="service-block" class="wp-block default grey-glow">
            <div class="figure">
                <img alt="..." src="~/images/services/nav-icon-white.jpg" class="img-responsive">
            </div>
            <div class="wp-block-body services-text">
                <h2 id="test" class="title">Lorem Ipsum <span class="heavy-header" style="color:#001990;">Lorem Ipsum</span> Lorem Ipsum</h2>
                <p>Lorem Ipsum.</p>
            </div>
        </div>
    </div> 

$("#service-block").hover(function () {
    var originalHeight = $(this).find('.title').prop("id");
});

这是你想要的吗？

$("#service-block").hover(function () {
    var $elem = $(this).find('.title');
    console.log("id of element: ", $elem.attr("id"));
    console.log("height of element: ", $elem.height()); //added due to your variable name
});
