Question

I have found This http://jsfiddle.net/YCTDQ/对我来说对我的项目有用，但是当我看到包含库文件时，我没有在外部资源中看到它们，但它们包含在jsfiddle中。

如何让这2个外部资源正确使用它们。

在jsfiddle中，代码显示正确，但我无法在下面显示的代码段中添加库文件。

$(function(){
    $('select').combobox();
});

/* 
    Combobox widget 
    - taken from http://jqueryui.com/autocomplete/#combobox
    - added support for
      - default option
      - combo uses width of original select
      - autoFocus
    - removed
      - tooltips
      - setting value to "" if invalid (instead sets to default)

你可以在这里找到它们并选择你想要的网址。

https://cdnjs.com/libraries/jqueryui

然后添加为脚本（通常在页眉或页脚中）

这方面的一个例子是：

<script src="https://cdnjs.cloudflare.com/ajax/libs/jqueryui/1.9.2/jquery-ui.min.js"></script>

其他更新：

因此，这两个脚本是https://cdnjs.cloudflare.com/ajax/libs/jquery/1.9.1/jquery.min.js和https://cdnjs.cloudflare.com/ajax/libs/jqueryui/1.9.2/jquery-ui.min.js

在你的html中你应该有类似下面的东西来使这个脚本工作。

<head>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jqueryui/1.9.2/jquery-ui.min.js"></script>
<script src="yctdq_script.js"></script> 
<!-- you ca copy code to external file and call it yctdq_script.js or whatever you want to name it. Or you can paste it between the two script tags -->
</head>
......

<body> 
.....
<select style="width:300px">
    <option value>-Select a number-</option>
    <option value="1">One</option>
    <option value="2">Two</option>
    <option value="3">Three</option>
    <option value="4">Four</option>
    <option value="5">Five</option>
    <option value="6">Six</option>
    <option value="7">Seven</option>
    <option value="8">Eight</option>
    <option value="9">Nine</option>
    <option value="10">Ten</option>
</select>
.....
</body>
