如何移除WordPress中script标签的type属性以消除页面警告？

Hey there! Let's sort out that annoying warning popping up on every page of your WordPress site. That message is just letting you know that adding type="text/javascript" to your <script> tags is no longer needed—modern browsers automatically recognize script tags as JavaScript, so that attribute is redundant now.

Here are a few practical ways to fix it:

• Check and edit your theme's template files
  Head over to Appearance > Theme Editor in your WordPress dashboard. Look for files like header.php or footer.php (where most site scripts are loaded). Search for instances of <script type="text/javascript"> and remove the type="text/javascript" part, leaving just <script>.
  Pro tip: Always back up your theme files first, or use a child theme to make edits—this way, your changes won't get overwritten when the theme updates.

• Filter script tags with a WordPress hook
  If the warning is coming from plugins or scripts enqueued via WordPress's built-in functions, you can use the script_loader_tag filter to strip out the type attribute automatically. Add this code to your theme's functions.php file, or use a code snippet plugin like Code Snippets to avoid editing theme files directly:

  add_filter('script_loader_tag', function($tag, $handle) {
      // Remove the unnecessary type attribute from all script tags
      return str_replace("type=\"text/javascript\"", "", $tag);
  }, 10, 2);
  

  This function will run every time a script loads on your site and clean up the redundant attribute automatically.

• Fix enqueued scripts manually
  If you're adding custom scripts using wp_enqueue_script() in your theme or plugin, double-check that you aren't manually setting the type attribute. The default behavior of wp_enqueue_script() doesn't add this attribute, but if you've included it in the optional arguments, remove it. For example:

  • Before (with unnecessary type):

    wp_enqueue_script('custom-script', get_template_directory_uri() . '/js/custom.js', array(), '1.0', true, array('type' => 'text/javascript'));
    

  • After (fixed):

    wp_enqueue_script('custom-script', get_template_directory_uri() . '/js/custom.js', array(), '1.0', true);
    

This warning doesn't break your site's functionality, but fixing it will clean up your browser console and keep your code aligned with modern web standards.
