$('.header').on('click', '.search-toggle', function(e) {
  var selector = $(this).data('selector');

  $(selector).toggleClass('show').find('.search-input').focus();

这样做：

document.querySelectorAll( '.header' ).forEach( function( item1, index1 ) {
    document.querySelectorAll( '.search-toggle' ).forEach( function( item2, index2 ) {
        item2.addEventListener( 'click', function( e ) {
            var selector = item2.dataset[ 'selector' ];

            document.querySelector( selector ).classList.toggle( 'show' );
            document.querySelector( selector + ' .search-input' ).focus();
            item2.classList.toggle( 'active' );
            e.preventDefault();
        } )
    } )
} )
