即使在 javascript 和 thymeleaf 中刷新后也禁用多个按钮

Question

问题

我有多个连接到数据库的按钮来记录点击次数。它们在一列中，每次您单击一个按钮时，与该按钮关联的值都会增加一个。

数据库 table 如下所示：

id  party name  vote 
'1', 'Vulcan', '0'
'2', 'Romulan', '0'
'3', 'Klingon', '0'
'6', 'Rick & morty', '0'
'25', 'updated test', '0'

我想要的是：当您单击任何按钮时，它应该禁用所有按钮，但仍会增加已单击的按钮，同时还保存 cookie 会话，因此即使在刷新页面后您也无法单击任何按钮。所以点击后所有按钮应该disappear/disabled。

我试过什么？

我已经尝试了很多方法，例如 this，但都不起作用。按钮仍然有效，增量仍然发生。

这是我的 html 页面，上面显示了图片

            if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length, c.length);

        return null;
    }

    $('#voted').click(function(){
        $(this).attr('disabled',true);

    });
    if(getCookie('DisableBtn'))
        $('#clic').attr('disabled',true);

这里是点击此处投票时获取的控制器

@GetMapping("/vote/{id}")
    public String getVote(@PathVariable Long id) {
        partyService.vote(id);
        
        return "redirect:/";
    }

Answer 1

您应该能够完全使用服务器端 cookie 来完成此操作。例如，这对我有用

控制器：

@GetMapping("/vote")
public String main(Map<String, Object> model, @CookieValue(name = "voted", defaultValue = "false") String voted) {
  model.put("voted", Boolean.parseBoolean(voted));
  return "vote";
}

@GetMapping("/vote/{id}")
public String vote(HttpServletResponse response, @CookieValue(name = "voted", defaultValue = "false") String voted, @PathVariable Long id) {
  if (!Boolean.parseBoolean(voted)) {
    partyService.vote(id);
    Cookie cookie = new Cookie("voted", "true");
    response.addCookie(cookie);
  }

  return "redirect:/vote";
}

按钮：

<button id="voted" th:disabled="${voted}">Vote Here</button>

即使在 javascript 和 thymeleaf 中刷新后也禁用多个按钮
