すべての検証作業を行うフォーム検証スクリプトがあります。しかし、パスワードが一致しないというアラートが表示されると、フィールドはクリアされますか? どうすればそれを避けることができますか?
<script type="text/javascript">
function formValidator(){
// Make quick references to our fields
var FNAME = document.getElementById('FNAME');
var LNAME = document.getElementById('LNAME');
var EMAIL = document.getElementById('EMAIL');
var GENDER = document.getElementById('GENDER');
var ADDRESS = document.getElementById('ADDRESS');
var CONTACTNO = document.getElementById('CONTACTNO');
var PASSWORD = document.getElementById('PASSWORD');
var PASSWORD2 = document.getElementById('PASSWORD2');
// Check each input in the order that it appears in the form!
if(isAlphabet(FNAME, "Please enter only letters for your first name"))
{
if(isAlphabet(LNAME, "Please enter only letters for last name"))
{
if(emailValidator(EMAIL, "Please enter a valid email address"))
{
if(madeSelection(GENDER, "Please Choose a Gender"))
{
if(isAlphanumeric(ADDRESS, "Numbers and Letters Only for Address"))
{
if(isNumeric(CONTACTNO, "Please enter only numbers for Contact No."))
{
if(lengthRestriction(PASSWORD, 6))
{
if (PASSWORD2 != PASSWORD)
{
alert ("You did not enter the same new password twice. Please re-enter your password.");
return true;
}
}
}
}
}
}
}
}
return false;
}
他の機能には問題ないと思いますか?
function notEmpty(elem, helperMsg){
if(elem.value.length == 0){
alert(helperMsg);
elem.focus(); // set the focus to this input
return false;
}
return true;
}
function isNumeric(elem, helperMsg){
var numericExpression = /^[0-9]+$/;
if(elem.value.match(numericExpression)){
return true;
}else{
alert(helperMsg);
elem.focus();
return false;
}
}
function isAlphabet(elem, helperMsg){
var alphaExp = /^[a-zA-Z]+$/;
if(elem.value.match(alphaExp)){
return true;
}else{
alert(helperMsg);
elem.focus();
return false;
}
}
function isAlphanumeric(elem, helperMsg){
var alphaExp = /^[0-9a-zA-Z]+$/;
if(elem.value.match(alphaExp)){
return true;
}else{
alert(helperMsg);
elem.focus();
return false;
}
}
function lengthRestriction(elem, min){
var uInput = elem.value;
if(uInput.length >= min){
return true;
}else{
alert("Please enter atleast " +min+ " characters");
elem.focus();
return false;
}
}
function madeSelection(elem, helperMsg){
if(elem.value == "Please Choose"){
alert(helperMsg);
elem.focus();
return false;
}else{
return true;
}
}
function emailValidator(elem, helperMsg){
var emailExp = /^[\w\-\.\+]+\@[a-zA-Z0-9\.\-]+\.[a-zA-z0-9]{2,4}$/;
if(elem.value.match(emailExp)){
return true;
}else{
alert(helperMsg);
elem.focus();
return false;
}
}

私はこの部分を間違っていると思いますか?? しかし、私はそれを修正する方法がわかりませんか?助けてください。
if (PASSWORD2 != PASSWORD)
{
alert ("You did not enter the same new password twice. Please re-enter your password.");
return true;
}
