Javascript 如何确保单击了哪个星形按钮

我正在使用codeigniter，我有一个表格，可以对产品进行评级。他们的I实现了星形按钮。每当我点击一个按钮，标签上就会显示一个“糟糕”的文本，以此类推。我需要知道的是，每当我提交表单时，我需要确保用户点击了任何星型按钮并给出了他/她的费率。这意味着必须给出利率。我怎样才能做到这一点。我知道这个。但它总是显示“您尚未提供评级”错误消息

Please help me.

实现它的方法之一是创建一个隐藏的输入并将其命名为
lblrating
。然后修改js，添加代码，当点击星号时更新
lblrating
输入的值。当用户按下“提交”按钮时，输入值将发送到服务器。实现该操作的方法之一是创建一个隐藏输入并将其命名为
