如何将本地存储连接到脚本？

<div class="wrapperchat">
   <div class="main-nav-chat">
      <div class="options">кнопка</div> 
   </div>
</div>

var active = localStorage['active'] == 'true';
$(".wrapperchat").toggleClass("wrapperchat-bottom", active);
$(".main-nav-chat .options").click(function(e) {
    e.preventDefault();
    active = !active;
    localStorage['active'] = active;
$(".wrapperchat").toggleClass("wrapperchat-bottom");
});
