javascript - 我的验证不正确，请看一下

问题描述

大家好，所以我想在这里用一些简单的javascript验证制作一个简单的html表单，

并且表单没有做它应该做的事情，我的javascript 验证功能根本不工作，只是什么都不做！！！！

我不知道我在做什么错？？？我错过了什么！？请看一下并给我您对该问题的意见，这是我的代码，并在此先感谢：

   <!DOCTYPE html>
<head>

  <title>Register</title>
  <script>
    function fill(){
    var x = document.getElementById("country").value;
    var ar = x.split(";");
    var c = document.getElementById("state");
    c.options.length = 0;
    for(i=0;i<ar.length;i++){
    var option = document.createElement("option");
    option.text = ar[i];
    c.add(option);
  }
}
function validateFn() {
  var fn = document.forms["form"]["fname"].value;
  var mi = document.forms["form"]["mi"].value;
  var ln = document.forms["form"]["ln"].value;
  var un = document.forms["form"]["un"].value;
  var city = document.forms["form"]["city"].value;
  var country = document.forms["form"]["country"].value;
  if (fn == "") {
    alert("First Name must be filled out");
    return false;
  }
  if (mi == ""){
    alert("Middle initial must be filled out");
    return false;
  }
  if (ln == ""){
    alert("Last Name must be filled out");
    return false;
  }
  if (un == ""){
    alert("User Name must be filled out");
    return false;
  }
  if (city == ""){
    alert("The City must be filled out");
    return false;
  }
  if (country == ""){
    alert("Select a Country");
    return false;
  }  

}
function validatePas() {
    var x= document.getElementById("password");
        var y= document.getElementById("rpassword");
    if(x.value==y.value) return;
    else alert("password not same");
    return false;
}

function ValidateEmail(inputText)
{
    var mailformat = /^[a-zA-Z0-9.!#$%&'*+/=?^_`{|}~-]+@[a-zA-Z0-9-]+(?:\.[a-zA-Z0-9-]+)*$/;
    if(inputText.value.match(mailformat))
    {
    return true;
    }
    else
    {
    alert("You have entered an invalid email address!");
    document.form.email.focus();
    return false;
    }
