尝试在JavaScript文件中调用函数没有任何操作

Trying to call a function inside JavaScript file has no action

本文关键字：函数 任何 操作 调用 JavaScript 文件      更新时间：2023-09-26

我重新创建了我这次尝试使用CLI开发的移动应用程序，这样我就可以用最简单的方法在Phonegap 3.4中添加插件

问题是，在我的JavaScript中，当我调用registerdb函数时，没有什么能正常工作。我的意思是，即使我在运行它时确实在密码或电子邮件文本区域出错，我也不会收到任何振动或错误消息

当我对registerdb和函数的调用发表评论时，JavaScript会一直正常工作，直到它结束（当每个文本输入都正确时，它会打印警报）

所以，我认为问题与函数registerdb的调用有关。有什么帮助吗？

我的.js文件： 

document.addEventListener("deviceready", onDeviceReady, false);
    // PhoneGap is ready
    function onDeviceReady() {
        // Empty
    }

// Function to add event listener to register button
function load() { 
  var el = document.getElementById("register"); 
  el.addEventListener("click", Register, false); 
} 
document.addEventListener("DOMContentLoaded", load, false);
function Register() {
  var username = document.getElementsByName('username')[0];
  var password = document.getElementsByName('password')[0];
  var email = document.getElementsByName('email')[0];
  if (username.value == "") {
    $("#username").focus();
    document.getElementById('username').style.boxShadow = "0 0 7px #f00";
    navigator.notification.vibrate(500);
  } 
  else{
    document.getElementById('username').style.boxShadow = "none";
  }
   //>5 characters, 1 upper case, at least 1 lower case, at least 1 numerical character, at least 1 special character
   var passExp = /(?=^.{6,15}$)((?=.*'d)(?=.*[A-Z])(?=.*[a-z])|(?=.*'d)(?=.*[^A-Za-z0-9])(?=.*[a-z])|(?=.*[^A-Za-z0-9])(?=.*[A-Z])(?=.*[a-z])|(?=.*'d)(?=.*[A-Z])(?=.*[^A-Za-z0-9]))^.*/;
   var strong_flag_pass = 0;
  if (!(password.value.match(passExp))) {
    $("#password").focus();
    document.getElementById('password').style.boxShadow = "0 0 7px #f00";
    navigator.notification.alert("Please enter a strong Password! It has to have at least: 6 characters, 1 upper case, 1 lower case, 1 numerical character and 1 special character!", null, 'Password', 'Okay');
    navigator.notification.vibrate(500);
    strong_flag_pass = 0;
  }
  else{
    document.getElementById('password').style.boxShadow = "none";
    strong_flag_pass = 1;
  }
  var emailExp = /^.+@[^'.].*'.[a-z]{2,}$/;
  var strong_flag_email = 0;
  if (!(email.value.match(emailExp))) {
    $("#email").focus();
    document.getElementById('email').style.boxShadow = "0 0 7px #f00";
    navigator.notification.alert("Please enter a correct Email!", null, 'Email', 'Okay');
    navigator.notification.vibrate(500);
    strong_flag_email = 0;
  }
  else {
    document.getElementById('email').style.boxShadow = "none";
    strong_flag_email = 1;
  }
  var gender = document.getElementById("gender").value;
  var about_me = document.getElementById("about-me").value;
  var age = document.getElementById("radio-choice").value;
  if (document.getElementById('radio-choice-1').checked) {
    age = document.getElementById('radio-choice-1').value;
  }
  else if (document.getElementById('radio-choice-2').checked) {
    age = document.getElementById('radio-choice-2').value;
  }
  else if (document.getElementById('radio-choice-3').checked) {
    age = document.getElementById('radio-choice-3').value;
  }
  else if (document.getElementById('radio-choice-4').checked) {
    age = document.getElementById('radio-choice-4').value;
  }
  else if (document.getElementById('radio-choice-5').checked) {
    age = document.getElementById('radio-choice-5').value;
  }
  else if (document.getElementById('radio-choice-6').checked) {
    age = document.getElementById('radio-choice-6').value;
  }
  if (username.value != "" && strong_flag_pass == 1 && strong_flag_email == 1){      
    alert(gender);
    alert(about_me);
    alert(age);
    //add to db
    registerdb(email, password, username, gender, about_me, age);
  }

 function registerdb(email, password, username, gender, about_me, age) {
   alert(gender);
   alert(about_me);
   alert(password;
 }
}

在我的.html中，我"调用"此函数的方式是：

                            <a href="#" id="register" data-role="button" data-theme="a">Register</a>

在alert(password; 之后缺少一个)

function registerdb(email, password, username, gender, about_me, age) {
    alert(gender);
    alert(about_me);
    alert(password);
}
