提交按钮确认删除不工作在rails 3

Question

我还是新来的铁轨和试图理解东西时删除多个项目。当我点击提交时，它可以工作，我可以删除多个项目，但是，无论我的确认响应如何，它都会删除。

我使用JavaScript来检测我的提交按钮的onclick事件，我的代码是：

$('.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?'); 
    }; 
}); 

我的提交按钮是：

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

为什么确认没有做正确的事？它删除，即使我按取消...

试试这个

$('.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?'); 
    }; 
});
