wp_localize_script无效

Question

我的主题中有以下代码functions.php但是当我调用console.log(pw_script_vars);变量时undefined.我错过了什么？

function mytheme_enqueue_scripts(){
    wp_enqueue_script( 'jquery' );

}
add_action( 'wp_enqueue_scripts', 'mytheme_enqueue_scripts');

function pw_load_scripts() {

    wp_enqueue_script('pw-script');
    wp_localize_script('pw-script', 'pw_script_vars', array(
            'alert' => __('Hey! You have clicked the button!', 'pippin'),
            'message' => __('You have clicked the other button. Good job!', 'pippin')
        )
    );


}
add_action('wp_enqueue_scripts', 'pw_load_scripts');

Answer 1

您没有包含任何javascript文件wp_enqueue_script.

function pw_load_scripts() {

    wp_enqueue_script('pw-script', get_template_directory_uri() . '/test.js');
     wp_localize_script('pw-script', 'pw_script_vars', array(
            'alert' => __('Hey! You have clicked the button!', 'pippin'),
            'message' => __('You have clicked the other button. Good job!', 'pippin')
        )
    );


}
add_action('wp_enqueue_scripts', 'pw_load_scripts');

创建一个test.js在主题目录中调用的空文件,它将起作用.

如果您再查看源代码,您会看到:

<script type='text/javascript'>
/* <![CDATA[ */
var pw_script_vars = {"alert":"Hey! You have clicked the button!","message":"You have clicked the other button. Good job!"};
/* ]]> */
</script>

然后pw_script_vars.alert,您可以键入控制台以获取"Hey! You have clicked the button!"消息.
