小提琴脚本在网站上不起作用

Question

如果我从此处复制代码： https : //jsfiddle.net/agt10exp/
它可以在小提琴上正常工作，但是当我在PC上制作一个新文件并将代码粘贴到其中时，我得到了相同的布局，但是它无法正常工作（添加了<html></html>和<script src....></script>到我的代码：
（请注意，我是Python程序员，所以问题可能出在我的HTML / Js知识上）

<html>
I am a </span><select name="parent_selection" id="parent_selection">
            <option value="">-- Please Select --</option>
            <option value="patient">Patient</option>
            <option value="doctor">Doctor or physician</option>
            <option value="school">School or parent</option>
            <option value="worker">Case worker</option>
        </select>
        <br /><span>and I need information on</span>
        <select name="child_selection" id="child_selection" onchange="location = this.options[this.selectedIndex].value;">
        </select>
</html>

              case 'patient':

您声明自定义脚本并添加jquery，但是它们必须是分开的：

<script src="http://code.jquery.com/jquery-latest.min.js"></script>
<script>

+注意jquery src url

编辑：此代码在我的Chrome浏览器中正常工作

<html>
I am a </span><select name="parent_selection" id="parent_selection">
        <option value="">-- Please Select --</option>
        <option value="patient">Patient</option>
        <option value="doctor">Doctor or physician</option>
        <option value="school">School or parent</option>
        <option value="worker">Case worker</option>
    </select>
    <br /><span>and I need information on</span>
    <select name="child_selection" id="child_selection" onchange="location = this.options[this.selectedIndex].value;">
    </select>
