Jquery在h1标签内添加div

Question

Using jquery, How would I wrap a div class around the text inside all h1 tags. Eg to make all

<h1> test </h1>

in a document into

<h1> <div class="wrap">test </div></h1> .

I am having a mental block. Any help would be much appreciated.

Answer 1

Try to use use $('h1').wrapInner('<div class="wrap" />');

But use a <span class="wrap" />

Demo jsBin

From the DOCS: http://api.jquery.com/wrapInner/

Answer 2

<div> is not valid inside of <h1> . You would be better off using a <span> . Pure JavaScript:

var h = document.getElementsByTagName('h1')[0],
    d = document.createElement('span');
while(h.firstChild) d.appendChild(h.firstChild);
h.appendChild(d);
d.className = "wrap";

But that said, can't you just apply the "wrap" class to the <h1> ?

Answer 3

// Get and wrap the content from the h1
var content = $('h1').html();
content = '<div class="wrap">' + content + '</div>';

// Reinsert the content into the h1
$('h1').html( content );

This can of course be done in a single line, but this made it a bit more clear.
