Question

民间，

我正在使用会话存储来创建最近访问的帐户列表。

我正在尝试从会话存储中删除状态为“DISABLED”的帐户。

队列可以包含6个点和任何我想要完全删除的禁用帐户。

但是，当我在我的机器上本地运行时，我看到的唯一帐户被禁用。我究竟做错了什么？任何帮助都会很棒。

  "use strict";

/**
 * Manages the Recently Accessed for customers and orders
 * It uses HTML5 Session Storage
 * When we get the recently accessed items from Session Storage, we get it as string
 * Convert that into an array with JSON.parse
 * Check against the current item and insert all items into a queue
 * Sort and remove dupes
 * Now add the new item
 * Convert the queue to an array so we can manage it
 * Then convert it to a string  with JSON.stringify
 * Store it back into the Session Storage

})(jQuery, window);

代码与预期行为相反
