如何获取多个范围的html内容并将值添加为类

Question

我的HTML：

<div class="inside">
   <ul class="fourcol first">
       <li class="amenity-item">Something: <span>0</span></li>
       <li class="amenity-item">Something: <span>0</span></li>
       <li class="amenity-item">Something: <span>1</span></li>
       <li class="amenity-item">Something: <span>0</span></li>
       <li class="amenity-item">Something: <span>1</span></li>
       <li class="amenity-item">Something: <span>0</span></li>
       <li class="amenity-item">Something: <span>1</span></li>
       <li class="amenity-item">Something: <span>1</span></li>
       <li class="amenity-item">Something: <span>0</span></li>
   </ul>
</div>

我要完成的工作：

<div class="inside">
   <ul class="fourcol first">
       <li class="amenity-item">Something: <span class="amenity-val-0">0</span></li>
       <li class="amenity-item">Something: <span class="amenity-val-0">0</span></li>
       <li class="amenity-item">Something: <span class="amenity-val-1">1</span></li>
       <li class="amenity-item">Something: <span class="amenity-val-0">0</span></li>
       <li class="amenity-item">Something: <span class="amenity-val-1">1</span></li>
       <li class="amenity-item">Something: <span class="amenity-val-0">0</span></li>
       <li class="amenity-item">Something: <span class="amenity-val-1">1</span></li>
       <li class="amenity-item">Something: <span class="amenity-val-1">1</span></li>
       <li class="amenity-item">Something: <span class="amenity-val-0">0</span></li>
   </ul>
</div>

我的尝试：

$(function() {

    var value_of_span = $.each('span.amenity-val').html()

    if (value_of_span == 0) {
        $('span.amenity-val').addClass('amenity-val-0');
    }

    if (value_of_span == 1) {
        $('span.amenity-val').addClass('amenity-val-1');
    }

})

Answer 1

您可以使用：

1） $.each()遍历.amenity-item内的所有span元素：

2） text()获取跨度内的文本

3） addClass()分别基于检索到的文本添加类

$.each($('.amenity-item span'), function () {
    var text = $(this).text();
    $(this).addClass('amenity-val-' + text);
});

Answer 2

DEMO

$('span').each(function() {
    var x = $(this).text();
    $(this).addClass('amenity-val-' + x);
});

这将遍历每个span标记，获取其文本并将其保存为var x，然后我们只需将类添加到该span即可。
