用jQuery制作下拉菜单

Question

I'm having a problem getting a dropdown image menu to display properly in my browser. 我在获取下拉图像菜单以在浏览器中正确显示时遇到问题。 The code is as follows 代码如下

<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>jquery test</title>

<style>
#webmenu{
width:340px;
}

</style>
</head>

<body>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script type="text/javascript">
$(window).load(function() { // makes sure the whole site is loaded
$("body select").msDropDown();
    })
</script>


<select name="webmenu" id="webmenu">
<option value="calendar" title="http://www.abe.co.nz/edit/image_cache/Hamach_300x60c0.JPG"></option>
<option value="shopping_cart" title="http://www.nationaldirectory.com.au/sites/itchnomore/thumbs/screenshot2013-01-23at12.05.50pm_300_60.png"></option>
<option value="cd" title="http://www.mitenterpriseforum.co.uk/wp-content/uploads/2013/01/MIT_EF_logo_300x60.jpg"></option>

</select>

</body>
</html>

I found the original code on github at http://jsfiddle.net/GHzfD/357/ but have not been able to reproduce it - am I making some kind of fundamental mistake? 我在github上的http://jsfiddle.net/GHzfD/357/上找到了原始代码，但无法复制它-我犯了某种基本错误吗？

Missing msdropdown plugins 缺少msdropdown插件

msdropdown and css msdropdown和CSS

Include this code befor you call msdropdown 在调用msdropdown之前包含此代码

<link rel="stylesheet" href="http://www.marghoobsuleman.com/mywork/jcomponents/image-dropdown/samples/css/msdropdown/dd.css">
<script src="http://www.marghoobsuleman.com/mywork/jcomponents/image-dropdown/samples/js/msdropdown/jquery.dd.min.js"></script>

in jsFiddle these external links are included too on the left panel here is snapshot . 在jsFiddle中，这些外部链接也包含在左侧面板中，这是快照。

在此处输入图片说明

Also read What is the difference between $(window).load and $(document).ready? 还请阅读$（window）.load和$（document）.ready有什么区别？

Update after OP's comment OP发表评论后更新

You are placing msdropdown plugin before you have included jQuery file . 您要在包含jQuery文件之前放置msdropdown插件。

msdropdown is a jQuery plugin so jQuery file must be added before the plugin script is called. msdropdown是一个jQuery插件，因此必须在调用插件脚本之前添加jQuery文件。

So it should look like this: 所以它应该看起来像这样：

put your scripts at bottom of the page and css at the top to improve page load speed. 将scripts放在页面bottom ，将css放在top以提高页面加载速度。

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="http://www.marghoobsuleman.com/mywork/jcomponents/image-dropdown/samples/js/msdropdown/jquery.dd.min.js"></script>
<script type="text/javascript">
    $(document).ready(function() {
        $("body select").msDropDown();
    });
</script>
