The example in this article describes how jQuery loops through child nodes and obtains values. Share it with everyone for your reference, the details are as follows:

Html code part:

<div class="left_tree_ad_btn_container">
 <ul>
  <li class="tree_ad_btn_bg"><img src="/images/insurance/3lianad_small.jpg" />
  </li>
 </ul>
 <ul>
  <li class="tree_ad_btn_bg have_bg"><img src="/images/insurance/3lianad_small.jpg" /></li>
 </ul>
 <ul>
  <li class="tree_ad_btn_bg"><img src="/images/insurance/3lianad_small.jpg" /></li>
  </ul>
</div>

JS code part:

var arrUl = jQuery(".left_tree_ad_btn_container > ul");
jQuery.each(arrUl, function(){
 alert(jQuery(this).find("img").attr("src"));
 alert(jQuery(this).find("li").attr("class"));
});
