提交按钮确认删除在rails 3中不起作用

Question

我对 Rails 还很陌生，并且在删除多个项目时试图理解一些东西。当我点击提交时，它可以工作并且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。

我正在使用 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情？即使我按取消它也会删除...

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?');
    };
});
