JQuery UI的一些函數錯誤TypeError：$（...）。accordion不是一個函數

我嘗試跟隨另一個問題線程在stackoverflow但沒有結果，我得到錯誤TypeError：$（...）。accordion is not一個使用手風琴功能的功能，但對於其他功能的JQuery UI如「效果」，其效果很好。

這是我在我的head.php文件中的代碼

<h3>Our Product</h3> 
<div id="accordion"> 
    <div id="accordion"> 
    <h3>Section 1</h3> 
    <div> 
    <p>Mauris mauris ante, blandit et, ultrices a, susceros. Nam mi. Proin viverra leo ut odio. Curabitur malesuada. Vestibulum a velit eu ante scelerisque vulputate.</p> 
    </div> 
    <h3>Section 2</h3> 
    <div> 
    <p>Sed non urna. Donec et ante. Phasellus eu ligula. Vestibulum sit amet purus. Vivamus hendrerit, dolor at aliquet laoreet, mauris turpis porttitor velit, faucibus interdum tellus libero ac justo. Vivamus non quam. In suscipit faucibus urna. </p> 
    </div> 
    <h3>Section 3</h3> 
    <div> 
    <p>Nam enim risus, molestie et, porta ac, aliquam ac, risus. Quisque lobortis. Phasellus pellentesque purus in massa. Aenean in pede. Phasellus ac libero ac tellus pellentesque semper. Sed ac felis. Sed commodo, magna quis lacinia ornare, quam ante aliquam nisi, eu iaculis leo purus venenatis dui. </p> 
    <ul> 
     <li>List item</li> 
     <li>List item</li> 
     <li>List item</li> 
     <li>List item</li> 
     <li>List item</li> 
     <li>List item</li> 
     <li>List item</li> 
    </ul> 
    </div> 
</div> 
</div> 
</div>

<script src="<?php echo base_url('assets/js');?>/jquery.contenthover.min.js" type="text/javascript"></script>

，這是我的js代碼，我使用外部文件把它放在頁腳

$(function() { 
$(".owl-carousel").each(function() { 
$(this).owlCarousel({ 
    items: 10, 
    singleItem: true, 
    autoPlay: true, 
    stopOnHover: true, 
    transitionStyle: true 
}); 
}); 

**$("#accordion").accordion({ 
    heightStyle: "content" 
});** 
});

我的代碼有什麼問題嗎？
