코드를 간략하게 줄이고 싶은데..

이 이상 짧아질 수 있을까요? 

<script type="text/javascript">

      window.onload = function(){

    var data_tab = localStorage.tab_flg;

    if ( data_tab === "tab_menu" ){

      $('.select_content li').css('display','none');

    $('.select_content li.select_menu').css('display','block');

    $('.select_wrap .select_box').css('display','none');

    $('.select_wrap .select_box.select_menu').css('display','block');

    $('.select_tab li').removeClass('select');

    $('.select_tab li.select_menu').addClass('select')

  }

localStorage.removeItem("tab_flg");

}

$(function() {

$('.select_tab li').click(function() {

var index = $('.select_tab li').index(this);

$('.select_content li').css('display','none');

$('.select_content li').eq(index).css('display','block');

$('.select_wrap .select_box').css('display','none');

$('.select_wrap .select_box').eq(index).css('display','block');

$('.select_tab li').removeClass('select');

$(this).addClass('select')

});

});

</script>
