javascript - 如何在 WordPress 中添加外部 javascript

Question

我想插入放置在 WordPress 文件夹中的外部 JavaScript。 如果我包括使用脚本标签，它会显示“<”预期错误 下面是我的代码

global $wpdb; 
include("/asset/php/chart4php/inc/chartphp_dist.php"); 

$p = new chartphp(); 

$p->data_sql = $wpdb->get_results("select t2.name, count(t1.id) as score from custom_status as t2 left join wpsp_ticket as t1 on t2.name =    t1.status group by t2.name");

$p->chart_type = "bar"; 

// Common Options 
$p->title = "Category Sales"; 
$p->xlabel = "Category"; 
$p->ylabel = "Sales"; 

 $color = array("#1AAF5D","#F2C500","#F45B00","#8E0000","#0E948C"); 
 $p->color = $color[rand(0,4)]; 

 $out = $p->render('c1'); 

尝试包含 js 文件

wp_enqueue_script( 'jquery' );
wp_enqueue_script( 'ajax_search' );
wp_register_script( 'chartphp', plugins_url('/asset/php/chart4php/chartphp.js', __FILE__), array('jquery'));

wp_enqueue_script( 'chartphp' );

我还想包含 3 个移动文件

<script src="/asset/php/chart4php/jquery.min.js"></script> 
<script src="/asset/php/chart4php/chartphp.js"></script> 
<link rel="stylesheet" href="/asset/php/chart4php/chartphp.css">

在 WordPress 中包含脚本的正确方法是使用 wp_enqueue_script() .

如果您之前注册了脚本，您可以简单地引用它:

You could either link a script with a handle previously registered using the wp_register_script() function, or provide this function with all the parameters necessary to link a script.

请注意，如果您在 dependencies 参数中包含默认脚本(例如 jQuery)，则无需单独注册和/或入队。
