调试器输出：
这个好像我之前也有遇到过，我是通过状态将它锁住的
麻烦提供能复现问题的代码片段（https://developers.weixin.qq.com/miniprogram/dev/devtools/minicode.html）
谢谢啊，

我找到原因了，是在form里写了bindsubmit="formSubmit"，又在button里写了bindtap="formSubmit"，
所以执行了两次。对form用法不熟练，大家了解一下，避免犯错。
提供一下可复现的代码片段
刚代码不全，补充了，代码片段怎么弄？情况就是一个form,提交按钮点一次，会执行两submit,两次传的值还不一样
