I have this HTML form and try to validate at client side.
This is the validation function at HTML form.
function registerValidate() {
var have_error = "No";
var email = $('#userEmail').val();
var pwd = $('#password').val();
var pwdr = $('#passwordr').val();
var email_re = /^[-a-z0-9~!$%^&*_=+}{\'?]+(\.[-a-z0-9~!$%^&*_=+}{\'?]+)*#([a-z0-9_][-a-z0-9_]*(\.[-a-z0-9_]+)*\.(aero|arpa|biz|com|coop|edu|gov|info|int|mil|museum|name|net|org|pro|travel|mobi|[a-z][a-z])|([0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}))(:[0-9]{1,5})?$/i;
if (!email.match(email_re)) {
$('#email-error').html('Please enter a valid email');
have_error = "Yes";
}else{
$('#email-error').html('');
}
}
When I click "Create My Account", all texts filled inside the text inputs disappeared and doesn't show the error message, even it should show error message.
What could be wrong?
When do you call this function? On form submit? Maybe you form have been submitted and all data field cleared.
Could you provide source code?

I am trying to write a JS function which blocks users from submitting a personal email. Here is the code. When I remove the "alert" line, the user is blocked from a successful form submission. But there is no alert that prompts them to enter a business email.
$("form").submit(function(){
// Get the email value from the input with an id="Email-2"
var email_addr = $('#Email-2').val();
// The regex to check it against
var re = '[a-zA-Z_\\.-]+#((hotmail)|(yahoo)|(gmail))\\.[a-z]{2,4}';
// Check if the email matches
if(email_addr.match(re)){
// Email is on the filter list
// Return false and don't submit the form, or do whatever
window.alert("Enter Business Email");
return false;
} else {
// Email ok
// Allow the form to be submitted
return true;
}});
Below is where there error is occuring. I'm new to Javascript so it very likely could be a syntax issue.
window.alert("Enter Business Email");
return false;
I found a solution that worked, changed the code to the following:
$('#wf-form-Book-Demo-Form').submit(function(){
var email = $('#Email-2').val();
var reg = /^([\w-\.]+#(?!gmail.com)(?!yahoo.com)(?!hotmail.com)(?!yahoo.co.in)(?!aol.com)(?!abc.com)(?!xyz.com)(?!pqr.com)(?!rediffmail.com)(?!live.com)(?!outlook.com)(?!me.com)(?!msn.com)(?!ymail.com)([\w-]+\.)+[\w-]{2,4})?$/;
if (reg.test(email)){
return 0;
}
else{
alert('Please Enter Business Email Address');
return false;
}
});
I wanted to ask how can i get the values of the Javascript Input and store it into a php value so i can post this data into Sqlite3. Im receiving user inputs from the Javascript Prompts. Is there another way to accomplish this also. Any help would be greatly appreciated.
function myFunc(){
var code = prompt("Please enter authorized code twice for security purposes: ");
var email = prompt("Please enter email twice to continue: ");
if(code==""||code==null||code!="1234"){
//Handle Error
window.location.href="error.html";
}
}
document.onreadystatechange = () => {
document.addEventListener('readystatechange', event => {
if (event.target.readyState === "complete") {
myFunc();
}
});
}
Using jquery you can use the $.post method:
function myFunc() {
var code = prompt("Please enter authorized code twice for security purposes: ");
var email = prompt("Please enter email twice to continue: ");
var url = "phpToGetInputs.php";
var data = {
code: code,
email: email
}
$.post(url, data); // "send the data to the php file specified in url"
// code...
}
document.onreadystatechange = () => {
// code...
}
Then, in your PHP file (that you specified as the url)
phpToGetInputs.php:
<?php
if(isset($_POST['email'])) {
$email = $_POST['email']; // get the email input (posted in data variable)
$code = $_POST['code']; // get the code input (posted in data variable)
// do code that requires email and code inputs
}
?>
Use a jQuery post request to send the variable from javascript to php.
$.post([url], { "data" : text });

This form keeps on submitting even if it executes the return value, what is the problem with my code?
function formhash (form, password)
{
var pass1 = document.getElementById("password").value;
var pass2 = document.getElementById("cpassword").value;
var ok = true;
if (password != cpassword) {
//alert("Passwords Do not match");
document.getElementById("password").style.borderColor = "#E34234";
document.getElementById("cpassword").style.borderColor = "#E34234";
ok = false;
return;
}
else
{
$.post('insert_home.php'
{PRIMAID:PRIMAID,EDITCAP:EDITCAP,EDITIMG:EDITIMG,EB_TITLE:EB_TITLE}).done(function(data){
alert ("Book Successfully Updated");
location.reload();
});
var p = document.createElement("input");
form.appendChild(p);
p.name="p";
p.type="hidden";
p.value=hex_sha512(password.value);
password.value="";
form.submit();
}
}
You are calling form.submit();, remove it and it won't submit.
You are using the wrong variable names "password" and cpassword". You created pass1 and pass2 so you need to use those.
Change to this:
//You were using the WRONG variable names
if (pass1 != pass2) {
//alert("Passwords Do not match");
document.getElementById("password").style.borderColor = "#E34234";
document.getElementById("cpassword").style.borderColor = "#E34234";
ok = false;
return false;
}
I don't see where formhash() is used.
The code calls the submit, not the function.
If it submits the form, it' because it's falling in the else condition.
Add lots of "console.log("debug_X")" where "X" is a number different each time.
You have to add inside a console.log the value of pass1 and pass2.
Maybe you are passign a value instead of an object or maybe the reversed situation can happen also.
My instinct tells me to check both password object, and their values.
Also it tells me that you didn't check the content of pass1 and pass2 before posting a comment to Don Rhummy.
Check carefully and please search more before posting your next answer.
You can have the value by doing "console.log(pass1);" and by opening firebug and by checking the javascript console.
Remove Action attribute from Form.
I have two javascript files that I am using to validate an email address.
validate.js:
function checkEmail(userEmail) {
var email = userEmail
var emailFilter = /^([a-zA-Z0-9_\.\-])+\#(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/;
if (emailFilter.test(email.value)) {
//alert('Please provide a valid email address');
//email.focus;
return true;
}
else{
return false
}
}
navigation.js EDIT:
$(document).ready(function() {
//ADDED IMPORTS
var imported = document.createElement('script');
imported.src = 'lib/validation.js';
document.head.appendChild(imported);
console.log("DOCUMENT IS READY!");
var viewsWrapper = $("#views-wrapper");
var loginButton = $("#login-button");
var registerButton = $("#register-button");
// Login Link
// TODO: Unclear if needed
$("ul li.login").click(function() {
$.get('/login', function(data) {
viewsWrapper.html(data);
});
});
$('#usernamefield').blur(function() {
var sEmail = $('#usernamefield').val();
if ($.trim(sEmail).length == 0) {
alert('Please enter valid email address');
e.preventDefault();
}
if (checkEmail(sEmail)) {
alert('Email is valid');
}
else {
alert('Invalid Email Address');
e.preventDefault();
}
});
...(more code follows but not relevant)
I am also using this jade template:
login.jade:
form(action="")
key EMAIL
input(type="text", name="username", id="usernamefield")
p hello world
br
key PASSWORD
input(type="text", name="password", id="passwordfield")
p hello world
br
input(type="submit", name="loginButton", id="login-button", value="LOGIN")
My issue is that when I input something into my email field, I do not get an alert message in any case. Am I allowed to just have to separate javascript files and call the methods I defined in validate.js within navigation.js? I tried putting the validate.js code in navigation.js, but even then it did not work. I would like to keep the files separate. Am I missing something obvious? I want it so that once the user inputs the email, and leaves the field, a message should appear warning if the email is valid or not.
Your help is appreciated.
Is it the blur Event or the checkEmail the problem? try to put a alert() or console.log() just after your blur (and make sure to lose focus on your input). Seperate file shouldn't be a problem. And also have you check for errors in your console ?
JavaScript string has no "value" field
After
var sEmail = $('#username').val();
sEmail becomes a string.
You are passing this string to checkEmail method and try to get "value" from a string:
if(!emailFilter.test(email.value)) {//...}
Replace to
if (!emailFilter.test(email)) {//...}
You are already sending the value of email into checkemail function. So in checkEmail function in validate.js remove email.value in second line of function checkEmail
function checkEmail(userEmail) {
var email = userEmail
var emailFilter = /^([a-zA-Z0-9_\.\-])+\#(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/;
if (!emailFilter.test(email)) {
//alert('Please provide a valid email address');
email.focus;
return false;
}
}
In my short script, that is checking if submited email is in the right form, I always recive alert, no matter what I put in the form (email)
function checkEmail() {
var mail = document.getElementById('mail');
var filter = /^([a-zA-Z0-9_\.\-])+\#(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/;
if (!filter.test(mail.value))
{
alert('Prosimo, vnesite veljaven email');
mail.focus;
return false;
}
}
