Question

我为我的wordpress网站创建了小插件/小部件。它只是获取对象数组并以一种不错的方式打印出来。效果很好，但我注意到，当其激活时，下拉菜单不起作用/我的插件干扰了下拉菜单功能。

我在使用Jquery时遇到问题。它会说它是未定义的，但我设法解决了，这可能是问题吗？

Features.php

if(!defined("ABSPATH")){
    exit;
}

// load scripts
require_once(plugin_dir_path(__File__)."includes/Features-scripts.php");
// load class
require_once(plugin_dir_path(__File__)."includes/Features-class.php");

//register widget

function register_Features(){
    register_widget("Features");
}

// hook in function 

add_action("widgets_init","register_Features");

Features-script.php

function f_add_scripts(){
    //add css and js
    wp_enqueue_style("f-main-style", plugins_url()."/Features/css/style.css");
    wp_enqueue_script("f-main-script", plugins_url()."/Features/script/script.js");
    wp_enqueue_script( 'f-jquery', 'https://code.jquery.com/jquery-3.3.1.js', array( 'jquery' ) );

我解决了这个问题。我将jquery从Features-script.php移到Features.php

所以现在Feature.php看起来像这样

if(!defined("ABSPATH")){
    exit;
}

// load scripts
require_once(plugin_dir_path(__File__)."includes/Features-scripts.php");
// load class
require_once(plugin_dir_path(__File__)."includes/Features-class.php");

//register widget

function register_Features(){
    register_widget("Features");
    wp_register_script( 'jquery_Features',"https://code.jquery.com/jquery-3.3.1.js");
    wp_enqueue_script('jquery_Features');
}

// hook in function 

add_action("widgets_init","register_Features");
