jQuery prev() and next()

I am using jQuery. I have HTML code which looks like this:

<ul>
    <li>123</li>
    <li id="hello">456</li>
</ul>
<ul>
    <li>78开发者_开发问答9</li>
</ul>

I want, with jQuery, to get the li element after #hello (the 789 element). I tried with $('#hello').next(), it does not work.

How do I do?

---

$('#hello').parent().next().children();

• the parent()^[docs] method to go up to the <ul> element

• the next()^[docs] method to go to the next <ul> element

• the children()^[docs] method to get the nested <li> element

---

try something like

$('#hello').parent().next().children().eq(0)
