如何将div包裹在物品周围？

Question

我的代码在每个5个子div周围包装了一个div。 但是包装只能在div“ partnerwrap”中进行，有人可以帮助我吗？

 var divs = $(".partnerwrap > .partner_item"); for (var i = 0; i < divs.length; i += 5) { divs.slice(i, i + 5).wrapAll("<div class='group'></div>"); } 

 .partner_item { width: 50px; height: 50px; margin: 10px; float: left; background-color: #999; } 

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <div class="content1"> <div class="partnerwrap"> <div class="partner_item even">1</div> <div class="partner_item odd">2</div> <div class="partner_item even">3</div> <div class="partner_item odd">4</div> <div class="partner_item even">5</div> <div class="partner_item odd">6</div> <div class="partner_item even">7</div> <div class="partner_item odd">8</div> </div> </div> <div class="content2"> <div class="partnerwrap"> <div class="partner_item even">9</div> <div class="partner_item odd">10</div> </div> </div>

如果使用Id标识内容div，并使用类对它们进行分组，则可以执行以下操作：

 $(".content").each(function() { var divs = $(".partnerwrap > .partner_item", this); for (var i = 0; i < divs.length; i += 5) { divs.slice(i, i + 5).wrapAll("<div class='group'></div>"); } }); 

 .partner_item { width: 50px; height: 50px; margin: 10px; float: left; background-color: #999; } 

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <div class="content1"> <div class="partnerwrap"> <div class="partner_item even">1</div> <div class="partner_item odd">2</div> <div class="partner_item even">3</div> <div class="partner_item odd">4</div> <div class="partner_item even">5</div> <div class="partner_item odd">6</div> <div class="partner_item even">7</div> <div class="partner_item odd">8</div> </div> </div> <div class="content2"> <div class="partnerwrap"> <div class="partner_item even">9</div> <div class="partner_item odd">10</div> </div> </div>
