jquery loops iterate through the child nodes and gets the value of the method _jquery

The example in this article describes how jquery loops through subnodes and gets values. Share to everyone for your reference, specific as follows:

HTML code section:

<div class= "Left_tree_ad_btn_container" >
 <ul> <li class= "TREE_AD_BTN_BG" >
  </li>
 </ul>
 <ul>
  <li class=" Tree_ AD_BTN_BG have_bg "></li>
 </ul>
 < ul>
  <li class= "TREE_AD_BTN_BG" ></li>
  </ul>
</div>

JS Code section:

var Arrul = JQuery (". Left_tree_ad_btn_container > ul");
Jquery.each (Arrul, function () {
 alert (jQuery). FIND ("img"). attr ("src"));
 Alert (JQuery (this). Find ("Li"). attr ("class"));
