Python Web Scraping：无法从bs4元素中提取文本(Python Web Scraping: Unable to extract text from bs4 element)

 据我所知，你希望将子菜单悬停在上面一级的列表项上 
 
<ul class="submenu">
    <li><a href="#">Working With Us</a></li>
    <li><a href="#">Work Culture</a>
        <ul class="submenu">
            <li><a href="#">Benefits</a></li>
        </ul>
    </li>
</ul>
 
 我将子菜单类添加到我希望它们最初隐藏的所有元素中。 然后我对jquery代码进行了一些修改，以便与所有子菜单一起使用 
 
$('ul.submenu').hide();
$('ul.nav > li, ul.submenu > li').hover(function () {
if ($('> ul.submenu',this).length > 0) {
    $('> ul.submenu',this).stop().slideDown('slow');
}
},function () {
    if ($('> ul.submenu',this).length > 0) {
        $('> ul.submenu',this).stop().slideUp('slow');
    }
});
 
 希望这对你有用http://tsfiddle.net/U7mqM/ 

as far as i understood you want to slidedown the submenu on hovering the list item one level above
 
<ul class="submenu">
    <li><a href="#">Working With Us</a></li>
    <li><a href="#">Work Culture</a>
        <ul class="submenu">
            <li><a href="#">Benefits</a></li>
        </ul>
    </li>
</ul>
 
i added the submenu class to all elements i want them to be initially hidden. then i made some modifications on the jquery code to work with all submenus
 
$('ul.submenu').hide();
$('ul.nav > li, ul.submenu > li').hover(function () {
if ($('> ul.submenu',this).length > 0) {
    $('> ul.submenu',this).stop().slideDown('slow');
}
},function () {
    if ($('> ul.submenu',this).length > 0) {
        $('> ul.submenu',this).stop().slideUp('slow');
    }
});
 
hope this will work for you see http://jsfiddle.net/U7mqM/
