如何使2个jQuery函数工作？

我的网站上有两个jQuery函数：一个fotoslider和一个Scrollit函数。但是我只能使用一个函数，因为另一个函数不起作用。这取决于我把哪个放在底部

<link href="ppgallery/css/ppgallery.css" rel="stylesheet" type="text/css" />
<link href="ppgallery/css/dark-hive/jquery-ui-1.8.6.custom.css" rel="stylesheet" type="text/css" />
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.6/jquery-ui.min.js"></script> 
<script type="text/javascript" src="ppgallery/js/ppgallery.js"></script> 
<script type="text/javascript">
$(document).ready(function() {
    $('#gallery').ppGallery();
});

我几乎不了解jQuery，但我需要在我的网站上使用这些功能

<link href="ppgallery/css/ppgallery.css" rel="stylesheet" type="text/css" />
<link href="ppgallery/css/dark-hive/jquery-ui-1.8.6.custom.css" rel="stylesheet" type="text/css" />
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.6/jquery-ui.min.js"></script> 
<script type="text/javascript" src="ppgallery/js/ppgallery.js"></script> 
<script type="text/javascript">
$(document).ready(function() {
    $('#gallery').ppGallery();
});

在这里工作的函数是fotoslider，因为它位于底部

<link href="ppgallery/css/ppgallery.css" rel="stylesheet" type="text/css" />
<link href="ppgallery/css/dark-hive/jquery-ui-1.8.6.custom.css" rel="stylesheet" type="text/css" />
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.6/jquery-ui.min.js"></script> 
<script type="text/javascript" src="ppgallery/js/ppgallery.js"></script> 
<script type="text/javascript">
$(document).ready(function() {
    $('#gallery').ppGallery();
});

Html:

<link href="ppgallery/css/ppgallery.css" rel="stylesheet" type="text/css" />
<link href="ppgallery/css/dark-hive/jquery-ui-1.8.6.custom.css" rel="stylesheet" type="text/css" />
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.6/jquery-ui.min.js"></script> 
<script type="text/javascript" src="ppgallery/js/ppgallery.js"></script> 
<script type="text/javascript">
$(document).ready(function() {
    $('#gallery').ppGallery();
});

PS:Fotoslider是一个插件

使用jquery

<link href="ppgallery/css/ppgallery.css" rel="stylesheet" type="text/css" />
<link href="ppgallery/css/dark-hive/jquery-ui-1.8.6.custom.css" rel="stylesheet" type="text/css" />
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.6/jquery-ui.min.js"></script> 
<script type="text/javascript" src="ppgallery/js/ppgallery.js"></script> 
<script type="text/javascript">
$(document).ready(function() {
    $('#gallery').ppGallery();
});

现在，您可以在jquery代码中使用$j而不是$

<link href="ppgallery/css/ppgallery.css" rel="stylesheet" type="text/css" />
<link href="ppgallery/css/dark-hive/jquery-ui-1.8.6.custom.css" rel="stylesheet" type="text/css" />
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.6/jquery-ui.min.js"></script> 
<script type="text/javascript" src="ppgallery/js/ppgallery.js"></script> 
<script type="text/javascript">
$(document).ready(function() {
    $('#gallery').ppGallery();
});

这些javascript库之间总是有冲突的可能

您有两个版本的jquery

1.4

和

1.8

，这是不允许的，这样您只能使用其中一个版本。因此，您可以选择

1.8

@Jai是正确的，我认为删除第二个文件并检查hi-thnx以获得回复。但是当我离开的时候

<link href="ppgallery/css/ppgallery.css" rel="stylesheet" type="text/css" />
<link href="ppgallery/css/dark-hive/jquery-ui-1.8.6.custom.css" rel="stylesheet" type="text/css" />
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.6/jquery-ui.min.js"></script> 
<script type="text/javascript" src="ppgallery/js/ppgallery.js"></script> 
<script type="text/javascript">
$(document).ready(function() {
    $('#gallery').ppGallery();
});
