If you don't want the script to load on a page, then don't include it. 
如果您不希望脚本加载到页面上，则不要包含它。 If you're using a CMS for your site, then post the CMS that you're using so we can help you. 如果您的网站使用的是CMS，请发布您正在使用的CMS，以便我们为您提供帮助。
If all that fails, you can set up something like an ID on your body tag. 如果一切失败，则可以在body标签上设置类似ID的内容。 Then you can test the ID of the body, if it passes, execute the code, if it fails, then don't execute it. 然后，您可以测试主体的ID，如果它通过了，则执行代码，如果它失败，则不要执行它。

An example would be something like this.. 一个例子就是这样。
<body id="home">
<script language="JavaScript">
function init() {
if(document.getElementsByTagName('body')[0].id == 'home') {
// We're grabbing the head and the script
var headElement = document.getElementsByTagName('head')[0],
scriptElement = document.createElement('script');
// We're setting the new script element to use the URL of the script we want
scriptElement.type= 'text/javascript';
scriptElement.src= 'http://slideshow.googlecode.com/files/jquery-ui.min.js';
// We're adding this newly created element to the head
headElement.appendChild(scriptElement);
}
}
init();
</script>
...
</body>
Try something like that. 尝试类似的事情。 For a greater explanation for using dynamic JavaScript elements, check out this page: http://unixpapa.com/js/dyna.html 有关使用动态JavaScript元素的更多说明，请查看以下页面： http : //unixpapa.com/js/dyna.html

If you want to controll this behaviour on the client side I would try this approach: 如果要在客户端控制此行为，请尝试以下方法：
<script>location.pathname == '/' && document.write('<script src="http://slideshow.googlecode.com/files/jquery-ui.min.js">\x3C/script>')</script>
But of course better to let you CMS/server code handle it for you. 但是，当然最好让CMS /服务器代码为您处理它。 But based on the information you provided I can only give you client-side solution. 但是根据您提供的信息，我只能为您提供客户端解决方案。

I believe you do something wrong, if you don't need script, just don't load it as Tim answered. 我相信您做错了什么，如果不需要脚本，请不要按照Tim的回答加载它。
Anyway possible workaround, you can create script yousrcipt.js , include it in every page. 无论如何，您都可以创建脚本yousrcipt.js包含在每个页面中。 In this script you can write something similar to this 在此脚本中，您可以编写类似以下内容
if (window.location == 'whateverhomepage') {
var head= document.getElementsByTagName('head')[0];
var script= document.createElement('script');
script.type= 'text/javascript';
script.src= 'http://slideshow.googlecode.com/files/jquery-ui.min.js';
head.appendChild(script);
}
