WrapAll() on multiple classes with multiple appearance

问题

Lets say this is my HTML

<ul class="products>
<li class="product">
<div class="product-title></div>
<div class="product-thumbnail></div>
<div class="product-price></div>
<div class="product-discription></div>
</li>
<li class="product">
<div class="product-title></div>
<div class="product-thumbnail></div>
<div class="product-price></div>
<div class="product-discription></div>
</li>
</ul>

Now I want to wrap .product-thumbnail and .product-price in

<div class="left"></div>

Like this

  <ul class="products>
       <li class="product">
        <div class="product-title></div>
        <div class="left">
         <div class="product-thumbnail></div>
         <div class="product-price></div>
        </div>
        <div class="product-discription></div>
       </li>

       <li class="product">
        <div class="product-title></div>
        <div class="left">
         <div class="product-thumbnail></div>
         <div class="product-price></div>
        </div>
        <div class="product-discription></div>
       </li>
    </ul>

This code does the trick if I had only one list item

$(".product-thumbnail, .product-price").wrapAll("<div class='left'></div>");

I've tried an each() on .product-thubnail and .product-price but without results..

Does anyone know how I could do this or how it could be done with each()?

回答1:

Iterate over the .product-title using each() method and combine with the immediate next element using add() method.

$('.product-title').each(function() {
  $(this).add($(this).next()).wrapAll('<div class="left"></div>')
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul class="products">
  <li class="product">
    <div class="product-title"></div>
    <div class="product-thumbnail"></div>
    <div class="product-price"></div>
    <div class="product-discription"></div>
  </li>
  <li class="product">
    <div class="product-title"></div>
    <div class="product-thumbnail"></div>
    <div class="product-price"></div>
    <div class="product-discription"></div>
  </li>
</ul>

Or iterate over the li and get both classes within the element by providing the context.

$('.product').each(function() {
  $('.product-title,.product-thumbnail', this).wrapAll('<div class="left"></div>')
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul class="products">
  <li class="product">
    <div class="product-title"></div>
    <div class="product-thumbnail"></div>
    <div class="product-price"></div>
    <div class="product-discription"></div>
  </li>
  <li class="product">
    <div class="product-title"></div>
    <div class="product-thumbnail"></div>
    <div class="product-price"></div>
    <div class="product-discription"></div>
  </li>
</ul>
