Question

<ul id="tab">
  <li onclick="clicker()" class="li01">one test</li>
  <li onclick="clicker()" class="li02">two test</li>
  <li onclick="clicker()" class="li03">three test</li>
  <div class="web_clear"></div>
</ul>
<div class="web_index">
  content....
</div>

I used document.getElementsByTagName("ul").childNodes; to get all the li. But it doesn’t work.

Answer 1

You can use the id

document.getElemensById("tab").childNodes;

Or if its the only ul then

document.getElementsByTagName("ul")[0].childNodes;
