Wrap some text in jQuery

Question

What I have:

<ul id="myId">
    <li>
        My text
        <ul class="myClass">
            <li>blahblahblah</li>
        </ul>
    </li>
</ul>

What I want:

<ul id="myId">
    <li>
        <span>My text</span>
        <ul class="myClass">
            <li>blahblahblah</li>
        </ul>
    </li>
</ul>

I don't have access to the HTML markup, and I want to do it using jQuery, Something like:

$('.myClass').get_the_text_ubove().wrap('<span>');

There must be some way to select "My text", although it does not have a class / id

Answer 1

Try:

$('#myId > li').each(
    function(){
        $(this.firstChild).wrap('<span></span>');
    });

Regarding the addition classto ul:

$('#myId > li').each(
    function(){
        $(this.firstChild).wrap('<span></span>');
        $(this).find('ul').addClass('myClass');
    });

Answer 2

Answer 3

var ul = document.getElementById("myId");
var li = ul.firstElementChild;
var text = li.firstChild;
var ul = li.childNodes[1];
ul.classList.add('myClass');
var span = document.createElement("span");
span.textContent = text.data;
li.replaceChild(span, text);

Old fashioned DOM to the rescue.
