我不明白在wordpress中脚本本地化是如何工作的。我用php创建了一个关联数组：
$translations = array(
\'value1\' =>\'This is first value\',
\'value2\' =>\'This is second value\'
);
我创建了简单的javascript文件，我想在其中使用这个数组：
jQuery(document).ready(function($){
alert(translations);
});
然后，我尝试在插件中排队并本地化此javascript文件，如下所示：
function kvkoolitus_load_comment_validation(){
wp_enqueue_script( \'simple-js\', plugin_dir_url( __FILE__ ) . \'js/jquery.simple.js\', array(\'jquery\'), \'\', true );
wp_localize_script( \'simple-js\', \'translations\', $translations );
}
add_action( \'wp_enqueue_scripts\', \'kvkoolitus_load_comment_validation\' );
但当我加载带有此javascript文件的页面时，警报会告诉我“translations”对象为null
我错过了什么？

从答案中复制here regarding variable scope
Variables inside a function are only available inside that function.
Variables outside of functions are available anywhere outside of functions,
but not inside any function.
因此，您需要添加
$translations 中的数组
kvkoolitus_load_comment_validation 功能，如
function kvkoolitus_load_comment_validation(){
$translations = array(
\'value1\' =>\'This is first value\',
\'value2\' =>\'This is second value\'
);
wp_enqueue_script( \'simple-js\', plugin_dir_url( __FILE__ ) . \'js/jquery.simple.js\', array(\'jquery\'), \'\', true );
wp_localize_script( \'simple-js\', \'translations\', $translations );
}
add_action( \'wp_enqueue_scripts\', \'kvkoolitus_load_comment_validation\' );
