jquery, wrap elements inside a div

问题:

I have this:

<div>content element</div>
<div class="accordionTrigger">
  <div><h1>title</h1></div>
  <p>text</p>
  <p>text</p>
  <p>text</p>
  ...
</div>
<div>content element</div>
<div>content element</div>

I need to wrap all the p-tags inside a div like this:

    <div>content element</div>
    <div class="accordionTrigger">
      <div><h1>title</h1></div>
      <div class="moreInfo">    
        <p>text</p>
        <p>text</p>
        <p>text</p>
        ...
      </div>
    </div>
    <div>content element</div>
    <div>content element</div>

can it be done with jQuery?

If I have more than one <div class="accordionTrigger"></div>, like this:

<div>content element</div>
<div class="accordionTrigger">
  <div><h1>title</h1></div>
  <p>text</p>
  <p>text</p>
  ...
</div>
<div>content element</div>
<div class="accordionTrigger">
  <div><h1>title</h1></div>
  <p>text</p>
  <p>text</p>
  ...
</div>

the result will be:

<div>content element</div>
<div class="accordionTrigger">
  <div><h1>title</h1></div>
  <p>text</p>
  <p>text</p>
  <p>text</p>
  <p>text</p>
  ...
</div>
<div>content element</div>
<div class="accordionTrigger">
  <div><h1>title</h1></div>
</div>

can I avoid that?

回答1:

Check the .wrapAll() method:

$('.accordionTrigger p').wrapAll('<div class="moreInfo"></div>');

The wrapAll() method will wrap all the elements matched into another element (compared to the .wrap() method which wraps the matched elements individually)

Check this it will work out as per expectation

<div>content element</div>
<div class="accordionTrigger">
  <div><h1>title</h1></div>


  <p>text</p>
  <p>text</p>
  <p>text</p>
  <script type="text/javascript"> 
      $("p").wrapAll("<div class='moreinfo'/>"); 
  </script>
</div>
<div>content element</div>
<div>content element</div>
