     ?>

       <?php wp_editor("Enter your text", "my_editor"); ?>

    <script>
    window.onload = function(){
        alert(tinyMCE.editors[0].getContent());
    }
    </script>

        <?php

    }


    }


?>

上面是我的代码，我在元数据箱中创建了一个自定义帖子和一个tinyMCE文本编辑器。但是为什么在执行alert(tinyMCE.editors[0].getContent());行时，它不起作用，也不显示编辑器的内容。萤火虫显示TypeError: tinyMCE.editors[0] is undefined

的错误

Answer 1

您可以提供编辑textarea的ID来获取tinyMCE的内容，您也应该获取已保存的post meta的内容并将其设置为编辑元素的文本以显示之前保存的值。您可以使用以下代码作为参考，

<?php
function taggr_meta_function($post){
 $my_editor = get_post_meta($post->ID, 'my_editor', true);
 wp_editor( $my_editor, "my_editor", array( 'textarea_name' => "my_editor" ) );
?>
   <script>
    window.onload = function(){
        alert(tinyMCE.get('my_editor').getContent());
    }
   </script>
<?php } ?>

为什么tinyMCE.editors不能在wordpress的tinyMCE上工作
