Bootstrap Datepicker没有加载任何CSS

Question

我正在尝试在我的MVC应用程序中创建一个bootstrap datepicker

数据选择器正在加载和创建，但控件没有附加任何样式。

我已确保包含datepicker3.css和bootstrap-datepicker.js文件，并且它们的状态代码为200，所以我不认为这些是问题。

控件的HTML

$('.datepickers').datepicker({
    format: 'dd/mm/yyyy'
});

的Javascript

mm/dd/yyyy

屏幕截图显示控件在屏幕

上的显示效果

值得注意的是，日期选择器也忽略了格式并使用dd/mm/yyyy代替$sessionId = get_session_id_that_locked_the_item_from_db(); if(session_status() !== PHP_SESSION_ACTIVE) { session_start(); } // get current session id. $current_id = session_id(); // renew activity. echo 'Renewed my activity.'; $_SESSION['active'] = 1; // Close the current session session_write_close(); if($current_id === $sessionId) { // the current user has locked the item. } // Check if the var active of this session exists. elseif(!checkSessionlastActivity($sessionId, $current_id)) { // Show the inventory item. showInventoryItem(); // Lock inventory when the item is selected(eg added to basket). if('I want to lock the item') { lockInventoryItem($current_id); } } else { echo 'Item is locked.'; } function checkSessionlastActivity($id, $current_id) { // switch session to the one that locked the item. session_id($id); session_start(); // get session is active. $active = ( isset($_SESSION['active'])? $_SESSION['active']: null); // Close the session. session_abort(); // restore current session. session_id($current_id); session_start(); if($active !== null) { return true; } return false; } function lockInventoryItem($current_id) { put_my_session_id_to_db($current_id); } function showInventoryItem() { echo 'You can select item'; }

谁能看到我哪里出错了？
