Jquery gets the property of the first li in ul when the list is loaded

Get the first li tag of ul by $("#top_menu li:first"). And then you can use it

Change the properties such as: $(" # top_menu li: first "). Attr (" class ", "select");

Trigger event: $("#top_menu li:first").click();

If you want to get the a tag under li, it is as follows:

$(" # top_menu li: first a ")

$("#top_menu li:first a").attr("","");

Trigger event: $("#top_menu li:first a").click();

<ul class="nav white" id="top_menu" name="top_menu">

<!--  Level 1 menu  -->

<s:iterator value="list" status="st">

<li><a onclick=""><s:property value="menuName" /></a></li>

</s:iterator>

</ul>
