我想插入 jQuery 插件下拉登录表单 让我的网站更漂亮，但我真的很困惑在哪里以及如何将 jQuery 插入到我的代码中。例如，以下是我的 index.php：

<?php
    include ('book_fns.php');
    session_start();
    do_html_header("Welcome to Store");
    echo "<p>Please choose a category:</p>";

    // Get categories out of database
    $cat_array = get_categories();

    // Display as links to cat pages
    display_categories($cat_array);

    //If logged in as admin, show add, delete, edit cat links.
    if(isset($_SESSION['admin_user'])) {
        display_button("admin.php", "admin-menu", "Admin Menu");
    }
    do_html_footer();
?>

我想将 jQuery 插件添加到我的索引页面的顶部。

I want to insert the jQuery plugin dropdown login form to make my website more pretty, but I am really confused where and how to insert jQuery into my code. For instance the following is my index.php:

<?php
    include ('book_fns.php');
    session_start();
    do_html_header("Welcome to Store");
    echo "<p>Please choose a category:</p>";

    // Get categories out of database
    $cat_array = get_categories();

    // Display as links to cat pages
    display_categories($cat_array);

    //If logged in as admin, show add, delete, edit cat links.
    if(isset($_SESSION['admin_user'])) {
        display_button("admin.php", "admin-menu", "Admin Menu");
    }
    do_html_footer();
?>

And I want to add the jQuery plugin to the top of my index page.

How do I insert this jQuery plugin?

直接从 CDN 获取。将此代码粘贴到页面的 HEAD 上：

<HTML>
   <HEAD>    
   <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
   </HEAD>
</HTML>

然后像使用常用的 javascript 代码一样使用该库，如下所示：

<script>
    $(document).ready(function() {
      alert('Hey! I was called when the document finished loading.');
    });
</script>

Get it straight from the CDN. Paste this code on your page's HEAD :

<HTML>
   <HEAD>    
   <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
   </HEAD>
</HTML>

Then utilize the library just as you would with your usual javascript code just like this one:

<script>
    $(document).ready(function() {
      alert('Hey! I was called when the document finished loading.');
    });
</script>

我认为您应该将标签回显到索引页，如下所示：

echo "<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script>"

或者您在中包含一个包含 jQuery 脚本的 HTML/PHP 文件。或者

include('headScript.php');

您编写一个与相呼应的函数上面的标签：

echo $this->headScript("http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js");

protected function headScript($src){
    return '<script type="text/javascript" src="$src"></script>';
}

I think you should echo the tag to your index page like this:

echo "<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script>"

Or you include an HTML/PHP file that contains jQuery script in the <head></head> tag

include('headScript.php');

Or you write a function that echo the <script></script> tag above:

echo $this->headScript("http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js");

protected function headScript($src){
    return '<script type="text/javascript" src="$src"></script>';
}
