如何在本机反应中从警报按钮将值传递给 function

Question

我正在尝试从警报按钮“是”调用并将值传递给我的 function，但它不起作用，function 未接收值并在我使用 ZC1C425268E683845D1AB5074F14 值时给出未定义的错误。 这是我的代码

    const sendemail = async ({ email, hash, password }) => {
        console.log(email); //getting Error here undefined email
    }
      Alert.alert(
                  "Account is not activated",
                  "kindly check your email box and verify your account.Do you want to Resend Verification Email ?",
                  [
                    {
                      text: "Yes",
                      onPress: () =>
                        this.sendemail(
                          email,
                         hash,
                          password
                        ),
                    },
                    {
                      text: "No",
                      // onPress: () => console.log("No"),
                    },
                  ]
                );

Answer 1

在 sendemail 调用中，您没有传递 object，而是传递了三个参数。 然后您尝试在该方法中解构 object。 试试这个：（我只删除了方法定义中的解构）

const sendemail = async ( email, hash, password ) => {
        console.log(email); 
    }
      Alert.alert(
                  "Account is not activated",
                  "kindly check your email box and verify your account.Do you want to Resend Verification Email ?",
                  [
                    {
                      text: "Yes",
                      onPress: () =>
                        this.sendemail(
                          email,
                         hash,
                          password
                        ),
                    },
                    {
                      text: "No",
                      // onPress: () => console.log("No"),
                    },
                  ]
                );

尝试消除

来自 Yes 的 onPress 方法的“() =>”，如果没有尝试在“() =>”中添加参数，那么它看起来像

onPress: (e, h, p) => this.sendemail(e, h, p),
