添加订单的时候也会报错

• bobby #1

  TypeError: 'NoneType' object is not subscriptable 这个报错不是引起添加订单错误的原因。 还有没有其他报错信息截图我看看呢

• 提问者 慕慕7077877 回复 bobby #2

  浏览器的请求地址会变成下面http://localhost:8080/undefined
  后端没有报错

只有修改个人信息才报这个错吧 其他情况下有没有这个问题？

• 慕沐7449560 #1

  老师我也遇到了同样的问题，除了修改个人信息会报这个错误，其他都是正常的

• 宝慕林7633073 #2

  我觉得好像是form表单的问题，点击按钮就会自动发送表单之类的，我把form改成section后就不会报错了
  
  (line 10 in userinfo.vue)
  <form name="formEdit" action="" method="post" >

  课程中有些地方逻辑是写的使用js发送。如果表单放到放到了form中就会导致发送两次 这个时候注释掉form 改成其他的html标签即可
