最終效果

技術要點

用戶協議 – 打開本地瀏覽器

點擊后，直接打開本地瀏覽器瀏覽網頁

 // 最終需修改為 《用戶協議》 的網址Linking.openURL("https://www.baidu.com");

手機號輸入框的 344 展示

onChangeText={(text: string) => {setPhone(formatPhone(text));
}}

export function formatPhone(phone: string): string {let trim: string = phone.replace(/\s+/g, "");const result = [trim.slice(0, 3), trim.slice(3, 7), trim.slice(7, 11)].filter((item) => !!item).join(" ");return result;
}

但在訪問接口登錄時，傳參需清除空格

UserStore.requestLogin(replaceBlank(phone), pwd, (success: boolean) => {

export function replaceBlank(phone: string): string {return phone ? phone.replace(/\s+/g, "") : "";
}

代碼實現
