toggle wrapInner with jquery -

i can't seem find toggle method jquery's wrap.

simply want toggle wrap of span when .toggle_comments clicked.

$( document ).on('click', '.toggle_comments', function( event ){      $( ).closest( "p" ).wrapinner( $( "<span class='inline-comments-highlight-text'></span>" ) );  }); 

you don't find because such method doesn't exist. like:

var      spanhtml = "<span class='inline-comments-highlight-text'></span>",     spansel  = "span.inline-comments-highlight-text" ;  $( document ).on('click', '.toggle_comments', function( event ) {     var $p = $(this).closest("p"),         $span = $p.children(spansel);      if ( $span.length ) {         $span.children().unwrap();     } else {         $p.wrapinner(spanhtml);     } });
