jQuery - use wrap() to wrap multiple elements?

Question

How would I go about using wrap() to wrap multiple elements (with different classes) inside a <div>?

For example, on the form I'm working on there is a big list of checkbox inputs and labels in the form of:

<input>
<label>
<input>
<label>

etc

I'm wanting to wrap a <div> around the input and label, so the result would be:

<div>
  <input>
  <label>
</div>
<div>
  <input>
  <label>
</div>

Thanks!

Answer 1

You can use the .wrapAll() method.

$('form > input').each(function(){
    $(this).next('label').andSelf().wrapAll('<div class="test"/>');
});

If your markup has always the exact same order, I'd prefer to use:

var $set = $('form').children();    
for(var i=0, len = $set.length; i < len; i+=2){
    $set.slice(i, i+2).wrapAll('<div class="test"/>');
}    

Should be significant faster.
