【问题描述】：
我有一种情况试图在现有的 wordpress 菜单中实现以下菜单样式。
// mynewmenu implementation
$('nav ul li').mouseover(function(e){
//Set the aesthetics (similar to :hover)
$('nav ul li').removeClass('hovered');
$(this).addClass('hovered');
});
var pageSize = 4,
$links = $(".pagedMenu li"),
count = $links.length,
numPages = Math.ceil(count / pageSize),
curPage = 1
;
showPage(curPage);
function showPage(whichPage) {
var previousLinks = (whichPage - 1) * pageSize,
nextLinks = (previousLinks + pageSize);
$links.show();
$links.slice(0, previousLinks).hide();
$links.slice(nextLinks).hide();
showPrevNext();
}
function showPrevNext() {
if ((numPages > 0) && (curPage < numPages)) {
$("#nextPage").removeClass('hidden');
$("#msg").text("(" + curPage + " of " + numPages + ")");
} else {
$("#nextPage").addClass('hidden');
}
if ((numPages > 0) && (curPage > 1)) {
$("#prevPage").removeClass('hidden');
$("#msg").text("(" + curPage + " of " + numPages + ")");
} else {
$("#prevPage").addClass('hidden');
}
}
$("#nextPage").on("click", function() {
showPage(++curPage);
});
$("#prevPage").on("click", function() {
showPage(--curPage);
});.hidden {
display: none;
}
body {
font: normal 1.0em Arial, sans-serif;
}
nav.pagedMenu {
color: red;
font-size: 2.0em;
line-height: 1.0em;
width: 8em;
position: fixed;

}
nav.pagedMenu ul {

}
nav.pagedMenu ul li {

<nav class="pagedMenu">

</ul>
</nav>
<div id="pagination">
<a href="#" id="prevPage" class="hidden">Previous</a>
<a href="#" id="nextPage" class="hidden">Next</a>
<span id="msg"></span>
</div>我做了什么：
在自定义CSS 主题部分，我用上面的jsfiddle CSS 代码更新了代码；
我已经更新了header.php，将nav id="full-menu" 替换为nav class="pagedMenu" 如下：
之前
<!-- Start Header -->
...
<div class="small-5 <?php if ($header_style == 'style2') { echo 'medium-8'; } else { echo 'medium-4';} ?> columns menu-holder">
<?php $full_menu_true = ($menu_mobile_toggle_view == 'style2' && $header_style == 'style2');?>
<?php if ($full_menu_true) { ?>
<nav id="full-menu" role="navigation">
<?php if ($page_menu) { ?>
<?php wp_nav_menu( array( 'menu' => $page_menu, 'depth' => 2, 'container' => false, 'menu_class' => 'full-menu', 'walker' => new thb_mobileDropdown ) ); ?>
<?php } else if(has_nav_menu('nav-menu')) { ?>
<?php wp_nav_menu( array( 'theme_location' => 'nav-menu', 'depth' => 2, 'container' => false, 'menu_class' => 'full-menu', 'walker' => new thb_mobileDropdown ) ); ?>
<?php } else { ?>
<ul class="full-menu">
<li><a href="<?php echo get_admin_url().'nav-menus.php'; ?>">Please assign a menu from Appearance -> Menus</a></li>
</ul>
<?php } ?>
</nav>
<?php } ?>
<?php if ($header_search != 'off') { do_action( 'thb_quick_search' ); } ?>
<?php if ($header_cart != 'off') { do_action( 'thb_quick_cart' ); } ?>
<a href="#" data-target="open-menu" class="mobile-toggle<?php if (!$full_menu_true) { ?> always<?php } ?>">
<div>
<span></span><span></span><span></span>
</div>
</a>
</div>
</header>
<!-- End Header -->
之后
<!-- Start Header -->
...
<?php $full_menu_true = ($menu_mobile_toggle_view == 'style2' && $header_style == 'style2');?>
<?php if ($full_menu_true) { ?>
<nav class="pagedMenu" role="navigation">
<?php if ($page_menu) { ?>
<?php wp_nav_menu( array( 'menu' => $page_menu, 'depth' => 2, 'container' => false, 'menu_class' => 'pagedMenu', 'walker' => new thb_mobileDropdown ) ); ?>
<?php } else if(has_nav_menu('nav-menu')) { ?>
<?php wp_nav_menu( array( 'theme_location' => 'nav-menu', 'depth' => 2, 'container' => false, 'menu_class' => 'pagedMenu', 'walker' => new thb_mobileDropdown ) ); ?>
<?php } else { ?>
<ul style="font-size: 28px;">
<li><a href="<?php echo get_admin_url().'nav-menus.php'; ?>">Please assign a menu from Appearance -> Menus</a></li>
</ul>
<?php } ?>
</nav>
<div id="pagination">
<a href="#" id="prevPage" class="hidden">Previous</a>
<a href="#" id="nextPage" class="hidden">Next</a>
<span id="msg"></span>
</div>
<?php } ?>
<?php if ($header_search != 'off') { do_action( 'thb_quick_search' ); } ?>
<?php if ($header_cart != 'off') { do_action( 'thb_quick_cart' ); } ?>
<a href="#" data-target="open-menu" class="mobile-toggle<?php if (!$full_menu_true) { ?> always<?php } ?>">
<div>
<span></span><span></span><span></span>
</div>
</a>
</header>
<!-- End Header -->
在script-calls.php、jquery 和jquery-ui-core 中已入队，我还注册了mynewmenu.js 一个文件，其中包含上面显示的jsfiddle 的jQuery 代码部分。
此时，菜单以某种方式显示，但没有动画，并且缺少下一个/上一个按钮；同样在 Chrome 控制台中，有一个错误 Uncaught TypeError: $ is not a functionreffering 到此行：$('nav ul li').mouseover(function(e){。
实时链接here。有什么想法吗？
