.wrapAll()

Categories: Manipulation > DOM Insertion, Around

.wrapAll( wrappingElement ) Returns: jQuery

Description: Wrap an HTML structure around all elements in the set of matched elements.

  • version added: 1.2.wrapAll( wrappingElement )

    wrappingElementAn HTML snippet, selector expression, jQuery object, or DOM element specifying the structure to wrap around the matched elements.

The .wrapAll() function can take any string or object that could be passed to the $() function to specify a DOM structure. This structure may be nested several levels deep, but should contain only one inmost element. The structure will be wrapped around all of the elements in the set of matched elements, as a single group.

Consider the following HTML:

<div class="container">
  <div class="inner">Hello</div>
  <div class="inner">Goodbye</div>
</div>

Using .wrapAll(), we can insert an HTML structure around the inner <div> elements like so:

$('.inner').wrapAll('<div class="new" />');

The new <div> element is created on the fly and added to the DOM. The result is a new <div> wrapped around all matched elements:

<div class="container">
  <div class="new">
    <div class="inner">Hello</div>
    <div class="inner">Goodbye</div>
  </div>
</div>

Examples:

Example: Wrap a new div around all of the paragraphs. 

<!DOCTYPE html>
<html>
<head>
  <style>

  div { border: 2px solid blue; }
  p { background:yellow; margin:4px; }
  </style>
  <script src="http://code.jquery.com/jquery-1.7rc2.js"></script>
</head>
<body>
  <p>Hello</p>
  <p>cruel</p>
  <p>World</p>
<script>$("p").wrapAll("<div></div>");</script>

</body>
</html>

Example: Wraps a newly created tree of objects around the spans. Notice anything in between the spans gets left out like the <strong> (red text) in this example. Even the white space between spans is left out. Click View Source to see the original html. 

<!DOCTYPE html>
<html>
<head>
  <style>

  div { border:2px blue solid; margin:2px; padding:2px; }
  p { background:yellow; margin:2px; padding:2px; }
  strong { color:red; }
  </style>
  <script src="http://code.jquery.com/jquery-1.7rc2.js"></script>
</head>
<body>
  <span>Span Text</span>
  <strong>What about me?</strong>
  <span>Another One</span>
<script>$("span").wrapAll("<div><div><p><em><b></b></em></p></div></div>");</script>

</body>
</html>

Example: Wrap a jQuery object double depth div around all of the paragraphs. Notice it doesn't move the object but just clones it to wrap around its target. 

<!DOCTYPE html>
<html>
<head>
  <style>

  div { border: 2px solid blue; margin:2px; padding:2px; }
  .doublediv { border-color:red; }
  p { background:yellow; margin:4px; font-size:14px; }
  </style>
  <script src="http://code.jquery.com/jquery-1.7rc2.js"></script>
</head>
<body>
  <p>Hello</p>
  <p>cruel</p>
  <p>World</p>
  <div class="doublediv"><div></div></div>
<script>$("p").wrapAll($(".doublediv"));</script>

</body>
</html>
