How to stop loader when alert box opens

How to stop loader when alert box opens - javascript

I have added a loader on my phonegap app on login button it works. but when Some alert occurs like password mismatch or invalid user, The loader doesn't stops. I have added my loader on html page, and want to stop at my Authentication js page in which alerts box are there in my html page to hide on next page I am using
<script language="javascript" type="text/javascript">
$(document).ready(function() {
$('#loading').hide();
});
</script>
how to hide my loader on js page alerts
if(Server == "" || UserName == "" || UserPass == "")
{
if(Server == "")
{
alert("Please enter server address");
}
if(UserName == "")
{
alert("Please enter User Name");
}
if(UserPass == "")
{
alert("Please enter Password");
}
}
else
{
strUrl="https://" + Server + ":1000";
//alert("Test"+strUrl);
sessionStorage.setItem("Server",Server);
window.localStorage.setItem("serUrl", strUrl);
window.localStorage.setItem("serUrl", strUrl);
window.localStorage.setItem("Server", Server);
strSerUrl="http://" + Server + ":8888/";
//alert(strSerUrl);
window.localStorage.setItem("ServerUrl", strSerUrl);
var DivId=sessionStorage.getItem('DivId');
DivId=window.localStorage.getItem("DivId")
// alert(DivId);
Identifier=Identifier+"_"+DivId;
//alert("Create Session1"+Identifier);
window.localStorage.setItem("Identifier", Identifier);
sessionStorage.setItem("Identifier",Identifier);
//alert("above create session")
services.CreateSession(Identifier, SystemID, UserName, UserPass, ConnectionEstablished, AuthenticationFailed);
}
}
function ConnectionEstablished(ResponseData) {
if (ResponseData != "")
{
//alert("resp"+ResponseData)
AuthenticationSuccess(ResponseData);
}
else
alert("Username or Password is incorrect!");
}

you can make the following change to your function to make it work:
function ConnectionEstablished(ResponseData) {
if (ResponseData != "")
{
//alert("resp"+ResponseData)
AuthenticationSuccess(ResponseData);
}
else
{
$('#loading').hide(); //hide the loader!
alert("Username or Password is incorrect!");
}
}
Try if it works!

Email validation Jquery not working

I have been working on a simple email validation. But it doesn't work.
Any ideas why it isn't working? Am I doing something wrong or should I structure my code in some other way?
I have done a function like this:
function IsEmail(email) {
var regex = /^([a-zA-Z0-9_\.\-\+])+\#(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/;
if(!regex.test(email)) {
return false;
} else {
return true;
}
}
and after that I'm calling that function in my setupRegistration function.
My JS looks like this:
function doOutputMessage(type, message){
$("#outputMessage").html("");
$("#outputMessage").removeClass();
$("#outputMessage").hide();
if(type == "error") {
$("#outputMessage").addClass("error").fadeIn("fast");
} else if(type == "success") {
$("#outputMessage").addClass("success").fadeIn("fast");
}
$("#outputMessage").text(message);
$("#outputMessage").show();
}
function setupRegistration(){
$("#signupWrapper").on("click", "#regUser", function(){
var username = $("input[name='username']").val();
var email = $("input[type='email']").val();
var password = $("input[type='password']").val();
if(username == ""){
doOutputMessage("error", "Fill in your desired username!");
}
if(email == ""){
doOutputMessage("error", "Fill in your email!");
}
if(IsEmail(email)==false){
doOutputMessage("error", "mailen är fel förfan");
}
if(password == ""){
doOutputMessage("error", "Fill in your desired password!");
}
if(username != "" && email != "" && password != ""){
ajaxCall(username, email, password);
}
});
}
function IsEmail(email) {
var regex = /^([a-zA-Z0-9_\.\-\+])+\#(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/;
if(!regex.test(email)) {
return false;
}else{
return true;
}
}
function ajaxCall(username, email, password){
$.ajax({
type: 'POST',
url: '../register.php',
data: {
'username' : username,
'email' : email,
'password' : password,
},
success: function(data) {
if(data.exists){
doOutputMessage("error","That Username is allready taken.");
} else if(data.inserted) {
doOutputMessage("success","You have successfully been registered!");
}else {
doOutputMessage("error","Something went wrong, try again later.");
}
}
});
}
$(document).ready(function(){
setupRegistration();
});
function regSubmit(){
clearErrorMessages();
var username = $("#regForm #username").val();
var email = $("#regForm #email").val();
var password = $("#regForm #password").val();
if(username == ""){
showValidationMessage("#regForm #error_username", "Fill in your desired username!");
}
if(email == ""){
showValidationMessage("#regForm #error_email", "Fill in your email!");
}
if(password == ""){
showValidationMessage("#regForm #error_password", "Fill in your desired password!");
}
if(username != "" && email != "" && password != ""){
$.ajax({
url: 'regLogin.code.php',
type: 'POST',
data: {
'action' : 'register',
'username' : username,
'email' : email,
'password' : password
},
success: function(data, status){
console.log(data);
if(data == "exist"){
showValidationMessage("#regForm #error_general", "A user with that username or password already exists!");
}else if(data == "illegal"){
showValidationMessage("#regForm #error_general", "Your username contains illegal characters!");
}
else if(data == "true"){
showValidationMessage("#regForm #success", "Success!");
setTimeout(function(){
window.location.replace("/admin/inside/");
}, 1000);
}
},
error: function(xhr, desc, err){
showValidationMessage("#regForm #error_general", "Something went wrong, please try again");
}
});
}
}

#Mario-Chueca is right. Your code is mostly working correctly, however, you are making an Ajax call regardless if the email is correct and as a result the error message is not shown. You should only make the ajax call when the specified email is valid:
if(username != "" && email != "" && password != "" && IsEmail(email)){
ajaxCall(username, email, password);
}
I have included a code sample below to show that your email validation (without Ajax call) is working. I have included the if(!IsEmail(email){ fix suggested by #Abdulla and I also also added a more complex regular expression from this post.
function IsEmail(email) {
//var regex = /^([a-zA-Z0-9_\.\-\+])+\#(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/;
//More advanced regex to valid 99.99% of most emails in use, see https://stackoverflow.com/questions/46155/validate-email-address-in-javascript
var regex = /^[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*#(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?/;
if (!regex.test(email)) {
return false;
} else {
return true;
}
}
function doOutputMessage(type, message) {
$("#outputMessage").html("");
$("#outputMessage").removeClass();
$("#outputMessage").hide();
if (type == "error") {
$("#outputMessage").addClass("error").fadeIn("fast");
} else if (type == "success") {
$("#outputMessage").addClass("success").fadeIn("fast");
}
$("#outputMessage").text(message);
$("#outputMessage").show();
}
//if (IsEmail('john.doe#stackoverflow.com')) {
// doOutputMessage('success', 'valid email')
//}
if (!IsEmail('john.doe#stackoverflow.com')) {
doOutputMessage('error', 'invalid email')
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="outputMessage">Test</div>

Use some of the advices from before, but change this too, the error doesn't stop the ajax call:
var error_email=false;
if(!IsEmail(email)){
error_email=true;
doOutputMessage("error", "mailen är fel förfan");
}
if(password == ""){
doOutputMessage("error", "Fill in your desired password!");
}
if(username != "" && email != "" && password != "" && !error_email){
ajaxCall(username, email, password);
}

remove false in here
if(!IsEmail(email){
and regex should be
regex = /^([\w-]+(?:\.[\w-]+)*)#((?:[\w-]+\.)*\w[\w-]{0,66})\.([a-z]{2,6}(?:\.[a-z]{2})?)$/i;

How to Find or Validate an Email Address

Confirm msg before submitting a form

i am validating a form and then asking for the confiormation through javascript…
so on submit i have called two function name validate() & make_confirm()..
onsubmit="return(validate() && show_alert(this));"
by this i am partially able to call both function but confirmation part is not working fine i have to redirect it to another page while pressing OK but its not going please help me out
validate & make_sure() function is as like:
function validate() {
if(document.getElementById('cname').value == '')
{
alert('Please enter your name');
document.getElementById('cname').focus();
return false;
}
else if(document.getElementById('address').value == '')
{
alert('Please enter your address');
document.getElementById('address').focus();
return false;
}
else if(document.getElementById('city').value == '')
{
alert('Please choose your city');
document.getElementById('city').focus();
return false;
}
else if(document.getElementById('state').value == '')
{
alert('Please enter your state');
document.getElementById('state').focus();
return false;
}
function make_sure() {
if(confirm("Do you really want to do this?"))
document.forms[0].submit();
else
return false;
}

Use one function for validate and confirm and set action of form to redirect form current page to another page.
function validateAndConfirm() {
if( isEmpty(id('cname').value) ) {
alert('Please enter your name');
id('cname').focus();
return false;
}
else if( isEmpty(id('address').value) ) {
alert('Please enter your address');
id('address').focus();
return false;
}
else if( isEmpty(id('city').value) ) {
alert('Please choose your city');
document.getElementById('city').focus();
return false;
}
else if( isEmpty(id('state').value) ) {
alert('Please enter your state');
id('state').focus();
return false;
} else {
if(confirm("Do you really want to do this?")) {
document.forms[0].submit();
}
else {
return false;
}
}
}
function isEmpty(val){
return (typeof val == 'undefined' || val === undefined || val == null || val.length <= 0) ? true : false;
}
// this function help to simplify you writing : document.getElementById to just id
function id(sid){
return document.getElementById(sid);
}

How to call the next page after button login clicked in XDK

In my login script when the username and password are both correct it must go to the next page (main/menu page) of the intel XDK.
My problem is how or what code can I use to call the next page whenever the username and password is correct (login successful)?
function validateForm() {
var formUsername = document.forms.login.username.value;
var formPassword = document.forms.login.password.value;
var MINLENGTH = 5;
// Validate username and password
if (formUsername === null || formUsername === "") {
alert("Username must be filled out");
}
else if (formPassword === null || formPassword === "") {
alert("Password must be filled out");
}
else if (formUsername.length < MINLENGTH || formPassword.length < MINLENGTH) {
alert("The minimum length of username and password at least " + MINLENGTH);
}
else if(formUsername == 'admin' && formPassword == 'admin'){
alert('welcome');
//this is where should i put the code to go at the next page of the XDK API.
return;
}
alert("Login failed!!!");
}

got it guys..
it will be.. like this ..
else if(formUsername == 'admin' && formPassword == 'admin'){
alert('welcome');
activated_page("#menu");
return;
}

JavaScript redirection error

I am trying to use JavaScript to redirect to a PHP page on my site, however, when I do it, nothing happens, apart from the alert boxes if I do not fill in the parameters. Is there something I am doing wrong?
document.getElementById("submit").onclick = check;
function check()
{
if(document.getElementById("name").value == "")
alert("The field 'Name' is required.");
else if (document.getElementById("message").value == "")
alert("The field 'Message' is required");
else
window.location.href = "scripts/main/contact.php?msg=" + document.getElementById("message").value;
}

Your default form action takes place overriding your redirect. Return false from the handler to prevent it from taking place:
function check()
{
if(document.getElementById("name").value == "")
alert("The field 'Name' is required.");
else if (document.getElementById("message").value == "")
alert("The field 'Message' is required");
else
window.location.href = "scripts/main/contact.php?msg=" + document.getElementById("message").value;
return false; // <------ here
}

JavaScript Load New Page Question

What I am looking to do is if a user complete a form it will provide access to a new location.
<script language="JavaScript" type="text/javascript">
<!--
function validateForm(theForm) {
var firstname = theForm.firstname.value;
var lastname = theForm.lastname.value;
var email = theForm.email.value;
if (firstname == "") {
alert("Please fill in your First Name.");
theForm.firstname.focus();
return false;
}
if (lastname == "") {
alert("Please fill in your Last Name.");
theForm.lastname.focus();
return false;
}
if (email == "") {
alert("Please fill in your email address.");
theForm.email.focus();
return false;
}
return true;
}
I know this part is wrong but I have no idea how to go about doing it. any help would be nice..
if lastname=""
if firstname=""
if email=""
load('www.google.com');

if (validateForm(theForm)) window.location = 'http://www.google.com';
Is equivalent to using
if (validateForm(theForm)) window.location.href = 'http://www.google.com';
Both will work, so choose which one you prefer.

if lastname=""
if firstname=""
if email=""
load('www.google.com');
becomes
if ((lastname == "") && (firstname == "") && (email == "")) {
window.location = "http://www.google.com";
}
