很简单啊！
你用jquery的ajax.get一个连接，url中指定待修改数据的唯一编号id，可以在点击的时候，把开关量也在url参数中一起传递，服务器端接收到访问请求，根据id和开关量做判断，修改，返回成功信息（根据情况也可以不用返回）。
哦，get的时候，有时候搜索引擎的蜘蛛会去访问这个地址，需要注意保护，防止数据泄露。
POST相对来说稳妥一些

When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4.
