在jQuery中每2个元素周围包裹一个div

Question

I have some HTML like this:

<span>Header Here</span>
<span>Content Here</span>
<span>Another Header</span>
<span>Some Other Content Here</span>

As you can see the HTML isn't really formatted in a very accessible way, and unfortunately I can't change the output, what I need to do is wrap every 2 spans with a div so the output becomes this:

<div class="row">
    <span>Header Here</span>
    <span>Content Here</span>
</div>
<div class="row offsetRow">
    <span>Another Header</span>
    <span>Some Other Content Here</span>
</div>

The offsetRow class will repeat every other row.

Is this even possible in jQuery?

You can use .wrapAll() like

 var $els = $('span'); for (var i = 0; i < $els.length; i += 2) { $els.slice(i, i + 2).wrapAll('<div class="row ' + (i > 0 && i % 2 == 0 && i % 4 != 0 ? 'offsetRow' : '') + '"></div>') } 

 .row { color: grey } .offsetRow { background-color: lightblue; } span { border: 1px solid red; }
