Javascript CakePHP 3.0-发布链接-添加类将删除警报确认功能

如何将类添加到此代码中

$this->Form->postLink(
    __('Delete'),
    ['action' => 'delete', $user->id],
    ['confirm' => __('Are you sure you want to delete # {0}?', $user->id)]
)

当我添加一个类时，确认功能消失

$this->Form->postLink(
    __('Delete'),
    ['action' => 'delete', $user->id],
    ['class' => 'btn btn-danger'],
    ['confirm' => __('Are you sure you want to delete # {0}?', $user->id)]
)

---

在确认之前设置类

['class' => 'btn btn-danger','confirm' => __('Are you sure you want to delete # {0}?', $user->id)]

确认和类应在同一数组中

$this->Form->postLink(
    __('Delete'),
    ['action' => 'delete', $user->id],
    ['confirm' => __('Are you sure you want to delete # {0}?', $user->id),'class'=>'btn btn-danger']
)

向我们显示添加类的代码。我得到了这个错误。错误：语法错误，意外=>\uuuuuuu常量\u封装的\u字符串，应为']'文件/Applications/AMPPS/www/tanv4\u cake\u主题/src/Template/Users/index.ctp行：59您的类是否包含在带有确认的数组中？完整的链接与你的例子，只是复制粘贴，这将做的工作回声$this->Form->postLink{uuuu'Delete'，['action'=>'Delete'，$user->id]，'class'=>'btn btn danger'，'confirm'=>\uuuu'you确定要删除{0}？，$\u club u\u user->id]看看代码高亮显示的@Gransfall你的代码例子中有语法错误，你缺少一个引号。是的，找到了，两者应该在同一个数组中。谢谢：
