提交按鈕確認刪除不工作在rails 3

Question

我還是新來的鐵軌和試圖理解東西時刪除多個項目。當我點擊提交時，它可以工作，我可以刪除多個項目，但是，無論我的確認響應如何，它都會刪除。

我使用JavaScript來檢測我的提交按鈕的onclick事件，我的代碼是：

$('.delete').on('click', function(){ 
    checked = countChecked(); 
    if (checked > 1) { 
     confirm('Are you sure you want to delete these ' + checked + ' entries?'); 
    } else { 
     confirm('Are you sure you want to delete this entry?'); 
    }; 
}); 

我的提交按鈕是：

<%= submit_tag "Delete Selected", { :class => 'delete'} %> 

爲什麼確認沒有做正確的事？它刪除，即使我按取消...

試試這個

$('.delete').on('click', function(){ 
    checked = countChecked(); 
    if (checked > 1) { 
     return confirm('Are you sure you want to delete these ' + checked + ' entries?'); 
    } else { 
     return confirm('Are you sure you want to delete this entry?'); 
    }; 
});
