我有3个用HTML设计的菜单项。 我希望我的第一个菜单项默认展开。
这是我的小提琴: FIDDLE
发布我的任何内容:
HTML
<div id="example1">
<ul id="menu1" class="example_menu">
<li><a class="expanded" href="#">Program 111</a>
<ul>
<li><a href="#">258275h</a>
</li>
<li><a href="#">264007</a>
</li>
<li><a href="#">270650b</a>
</li>
</ul>
</li>
<li><a class="collapsed" href="#">Program 112</a>
<ul>
<li><a class="collapsed" href="#">25875d</a>
</li>
<ul>
<li><a href="#">Release 1- Early Upgrade - 1404</a>
</li>
<li><a href="#">Release 2 - MDPP Umbrella Insurance</a>
</li>
</ul>
<li><a class="collapsed" href="#">269162a</a>
<ul>
<li><a href="#">Release 1- Early Upgrade - 1404</a>
</li>
<li><a href="#">Release 2 - MDPP Umbrella Insurance</a>
</li>
</ul>
</li>
</ul>
</li>
<li><a class="collapsed" href="#">Program 113</a>
<div>Hello</div>
<ul>
<li><a href="#">245875f</a>
</li>
<li><a href="#">2587940</a>
</li>
<li><a href="#">201254d</a>
</li>
</ul>
</li>
</ul>
</div>
JQuery的
$(document).ready(function () {
$('#menu1 li a').click(function () {
$(this).parent().children('ul').slideToggle('medium').toggleClass('collapsed').toggleClass('expanded');
//$(this).parent('ul').slideToggle('medium').toggleClass('collapsed').toggleClass('expanded');
$(this).parent().children('div').slideToggle('medium').toggleClass('collapsed').toggleClass('expanded');
});
});

一切都按预期工作,但我希望默认情况下展开第一个菜单项。 请保持温和,我是JQuery的新手。
