javascript - 在其他类(class)之后将内容导入类(class)

Question

是否可以使用 jQuery 将嵌套元素的文本存储在变量中？就我而言，内容是“SEO SEM”。

我唯一的引用是第一个名为 event_490 的类，我想获取类 evcal_event_title 等于“Seo SEM”的子元素的内容.

<div class="evo_lightbox_body eventon_list_event evo_pop_body evcal_eventcard event_489">
<div class="evopop_top" style="border-left-width: 3px; border-left-style: solid; border-left-color: rgb(33, 119, 189);">
<span class="ev_ftImg" data-img="http://localhost/academia/wp-content/uploads/2016/05/JBW2PXDOL6.jpg" data-thumb="http://localhost/academia/wp-content/uploads/2016/05/JBW2PXDOL6.jpg" style="background-image:url(http://localhost/academia/wp-content/uploads/2016/05/JBW2PXDOL6.jpg)"></span>
<span class="evcal_cblock " data-bgcolor="#2177bd" data-smon="junho" data-syr="2016">
    <em class="evo_date">
        <span class="start">11<em>jun</em>
        </span>
        <span class="end"> - 12</span>
    </em>
    <em class="evo_time">
        <em class="evo_day">jun 11</em>
        <span class="start">9:00</span>
        <em class="evo_day end">jun 12</em></em>
        <em class="clear"></em>
    </span>
    <span class="evcal_desc evo_info hide_eventtopdata " data-location_status="false">
        <span class="evo_above_title"></span>
        <span class="evcal_desc2 evcal_event_title" itemprop="name">Digital Stratety</span>
        <span class="evo_below_title">
            <span class="evcal_event_subtitle">09:00 - 18:00 | 16h | 155€</span>
        </span>
        <span class="evcal_desc_info"></span>
        <span class="evcal_desc3"></span>
       </span><em class="clear"></em>
    </div>
</div>

Answer 1

如果页面中的类不重复，您可以只使用类选择器 . 和 text() 函数:

$('.event_490 .evcal_event_title').text();

希望这有帮助。
