  Hey….i would like to defer js files and i have tried to use following code in my function.php

  function defer_parsing_of_js ( $url ) {
  if ( FALSE === strpos( $url, ‘.js’ ) ) return $url;
  if ( strpos( $url, ‘jquery.js’ ) ) return $url;
  return “$url’ defer “;
  }
  add_filter( ‘clean_url’, ‘defer_parsing_of_js’, 11, 1 );

  But with this code all xstore shortcodes are broken in their appearance…..

  Is there any hint to solve that problem?? Maybe any code to exclude the js files of the theme?

  Thanks a lot

  Hello,

  Try the following code instead of that one

  function defer_parsing_of_js ( $url ) {
  
  	if ( ( FALSE === strpos( $url, ‘.js’ ) )  || ( strpos( $url, ‘jquery.js’ ) > 0 ) || ( strpos( $url, ‘head.min.js’ ) > 0 ) ) return $url;
  
  	return “$url’ defer “;
  }

  Also, there is special WP plugin for these purposes WP deferred javaScript.

  Regards
