<button open-type=“getUserInfo” class=“bg-green” bindgetuserinfo=“bindGetUserInfo”>微信登陆</button>

bindGetUserInfo: function (e) {

    if (e.detail.userInfo) {

        console.log(‘用户按了授权按钮’)

        userInfo = e.detail.userInfo

        //wxlogin()

        console.log(e.detail.userInfo) //获取用户数据

}

请教一下，为什么这样写后，运行的时候出现这样的错误呢？

userInfo is not defined; [Component] Event Handler Error @ pages/index/index#bound bindGetUserInfo

ReferenceError: userInfo is not defined
