Javascript: Formular-Validierung getElementById nur zurückgeben erstes id element
Meine form der Validierung Skript scheint zu laufen, aber die getElementById ist nur das Lesen der ersten Id und überspringen Sie den rest aus irgendeinem Grund. Ist es aufgrund von geschlossenen Tags Probleme? Wenn ja, wo setze ich Sie? oder ist es ein weiterer Grund, die ich bin mit Blick irgendwie. Bitte helfen 🙁
Ich bin dankbar für jede Hilfe, ich habe gestarrt, an diesem Tage. Hier ist der code.
Den JS code.
<script type='text/javascript'>
function formValidator(){
//Make quick references to our fields
var name = document.getElementById('name');
var addr = document.getElementById('addr');
var phone = document.getElementById('phone');
var state = document.getElementById('state');
var username = document.getElementById('username');
var email = document.getElementById('email');
//Check each input in the order that it appears in the form!
if(isAlphabet(name, "Please enter only letters for your name")){
if(isAlphanumeric(addr, "Numbers and Letters Only for Address")){
if(isNumeric(phone, "Please enter only numeric values without any dashes")){
if(madeSelection(state, "Please Choose a State")){
if(lengthRestriction(username, 6, 8)){
if(emailValidator(email, "Please enter a valid email address")){
return true;
}
}
}
}
}
}
return false;
}
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]+$/;
if(elem.value.match(alphaExp)){
return true;
}else{
alert(helperMsg);
elem.focus();
return false;
}
}
function lengthRestriction(elem, min, max){
var uInput = elem.value;
if(uInput.length >= min && uInput.length <= max){
return true;
}else{
alert("Please enter between " +min+ " and " +max+ " characters");
elem.focus();
return false;
}
}
function madeSelection(elem, helperMsg){
if(elem.value == "Select State..."){
alert(helperMsg);
elem.focus();
return false;
}else{
return true;
}
}
function emailValidator(elem, helperMsg){
var emailExp = /^[\w\-\.\+]+\@[a-zA-Z0-9\.\-]+\.[a-zA-z0-9]{2,4}$/;
if(elem.value.match(emailExp)){
return true;
}else{
alert(helperMsg);
elem.focus();
return false;
}
}

?>Einmal validiert, wird es an eine php-mysql-Datei die Einträge in meine Datenbank. Nochmals vielen Dank für jede Hilfe.

Wenn dies ist eine JavaScript-Frage poste den resultierenden HTML-Code, nicht PHP... und ich glaube, Sie wäre eine bessere Trennung von Ihrem DOM Logik von Ihrem Validierungs-Logik, es scheint eine Menge von Wiederholung und kopieren/einfügen. Werfen Sie einen Blick auf diese Antwort stackoverflow.com/questions/9674148/...

Auf einer anderen Anmerkung, Sie sollten wahrscheinlich suchen zu schließen, dass die php-Tags statt der Verpackung alles in echo-Anweisungen. Mit CSS für Ihre Stile, sparen Sie eine Menge Kopfschmerzen in der Zukunft.
