[英]How do I load jquery library and a js file into wordpress theme?
I have been trying for the past day to load the jquery library and a js file into my WordPress theme but have no idea how to do this and everywhere I look the instructions are different and haven't worked. 我一直在尝试将jquery库和一个js文件加载到我的WordPress主题中,但不知道如何做到这一点,我看到的说明是不同的,并没有奏效。
Currently: 目前:
functions.php 的functions.php
<?php
function wpb_custom_new_menu() {
register_nav_menu('my-custom-menu',__( 'My Custom Menu' ));
}
add_action( 'init', 'wpb_custom_new_menu' );
function enqueue_stylesheets() {
wp_enqueue_style('style', get_stylesheet_directory_uri() . '/style.css');
}
function enqeue_scripts() {
wp_enqueue_script('homeSlider', get_stylesheet_directory_uri() . '/js/homeSlider.js', array('jquery'));
}
add_action('wp_enqueue_scripts', 'enqueue_stylesheets');
header.php header.php文件
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title><?php echo get_bloginfo( 'name' ); ?></title>
<meta name="description" content="<?php get_bloginfo( 'description' ); ?>">
<?php wp_head(); ?>
</head>
You need add the scripts what you want in the enqeue_scripts
function. 您需要在
enqeue_scripts
函数中添加所需的脚本。 You only need duplicate the current function and update it with the information that you need. 您只需复制当前函数并使用所需信息进行更新。 PD: jQuery is already loaded.
PD:jQuery已经加载了。
function enqeue_scripts() {
wp_deregister_script('jquery');
wp_register_script('jquery', 'https://code.jquery.com/jquery-2.2.4.min.js');
wp_enqueue_script('jquery');
wp_enqueue_script('homeSlider', get_stylesheet_directory_uri() . '/js/homeSlider.js', array('jquery'));
wp_enqueue_script('a unique name', 'source_path/js/another.js');
}
This is the function documentation 这是功能文档
The wp_enqueue_script
function need at least 2 parameters: a unique name (as string) and the path to the script. wp_enqueue_script
函数至少需要2个参数:唯一名称(作为字符串)和脚本的路径。 You can use the get_stylesheet_directory_uri
function to get the full path to the root theme directory and then concatenate the rest of path to the js file. 您可以使用
get_stylesheet_directory_uri
函数获取根主题目录的完整路径,然后将路径的其余部分连接到js文件。
The third parameter is an array of dependencies scripts. 第三个参数是依赖脚本数组。 Example: the current script in the code, named "homeSlide" has as dependency to jQuery.
示例:代码中名为“homeSlide”的当前脚本具有与jQuery的依赖关系。 If your script depends on jQuery, you need to specify it.
如果您的脚本依赖于jQuery,则需要指定它。
And, you need to hook this functions properly. 而且,您需要正确挂钩此功能。
add_action( 'wp_enqueue_scripts', 'enqeue_scripts' );
Your entire code should be like this: 你的整个代码应该是这样的:
<?php
function wpb_custom_new_menu() {
register_nav_menu('my-custom-menu',__( 'My Custom Menu' ));
}
add_action( 'init', 'wpb_custom_new_menu' );
function enqueue_stylesheets() {
wp_enqueue_style('style', get_stylesheet_directory_uri() . '/style.css');
}
function enqeue_scripts() {
wp_deregister_script('jquery');
wp_register_script('jquery', 'https://code.jquery.com/jquery-2.2.4.min.js');
wp_enqueue_script('jquery');
wp_enqueue_script('homeSlider', get_stylesheet_directory_uri() . '/js/homeSlider.js', array('jquery'));
}
add_action('wp_enqueue_scripts', 'enqueue_stylesheets');
add_action('wp_enqueue_scripts', 'enqeue_scripts');
It's not compulsory to add css & js files through functions.php file, you can directly add css & js files in header.php 通过functions.php文件添加css和js文件不是必须的,你可以直接在header.php中添加css和js文件
Just like this: 像这样:
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title><?php echo get_bloginfo( 'name' ); ?></title>
<meta name="description" content="<?php get_bloginfo( 'description' ); ?>">
//Include CSS files
<link rel="stylesheet" href="<?php echo esc_url( get_template_directory_uri() ); ?>/css/style.css">
//Including JS files
<script type="text/javascript" src="<?php echo esc_url( get_template_directory_uri() ); ?>/js/homeSlider.js"></script>
<?php wp_head(); ?>
</head>
I hope, this may help you. 我希望,这可能会对你有所帮助。
