Javascript 根据父元素和/或类使用新元素包装元素

我有三个不同的div类：designbox-triple、double和single。有多个div具有不同的类，它们都是浮动的，以便响应

<div class="collageWidgets">
    <div class="design-box-double"></div> <!--width 50%-->
    <div class="design-box-triple"></div> <!--width 33%-->
    <div class="design-box-triple"></div> <!--width 33%-->
    <div class="design-box-triple"></div> <!--width 33%-->
    <div class="design-box-double"></div> <!--width 50%-->
    <div class="design-box-double"></div> <!--width 50%-->
    <div class="design-box-single"></div> <!--width 100%-->
    <div class="design-box-single"></div> <!--width 100%-->
</div>

$（'.single'）.wrap（''）；
var double=$（'.double'）；
对于（var i=0；您正在应用的CSS
。行
是div的默认值。不应该是必需的。我添加了.slice（0,3）以选择相同类型的三个连续。
<div class="collageWidgets">
  <div class="row"> <!--width 100%-->
     <div class="design-box-double"></div> <!--width 50%-->
  </div>
  <div class="row"> <!--width 100%-->
     <div class="design-box-triple"></div> <!--width 33%-->
     <div class="design-box-triple"></div> <!--width 33%-->
     <div class="design-box-triple"></div> <!--width 33%-->
  </div>
  <div class="row"> <!--width 100%-->
     <div class="design-box-double"></div> <!--width 50%-->
     <div class="design-box-double"></div> <!--width 50%-->
  </div>
  <div class="row"><!--width 100%-->
     <div class="design-box-single"></div> <!--width 100%-->
  </div>
  <div class="row"><!--width 100%-->
     <div class="design-box-single"></div> <!--width 100%-->
  </div>
  <div class="row"> <!--width 100%-->
     <div class="design-box-triple"></div> <!--width 33%-->
     <div class="design-box-triple"></div> <!--width 33%-->
     <!-- Example missing triple, but won't look messed up because it is wrapped with a row 100% width, display block, and clearfix-->
  </div>
</div><!--End of Collage Widget Div-->
