Can I have yout help pleas there,I make a validation field for a popup form :
function prepareEventHandlers() {
document.getElementById("contact").onsubmit = function () {
if (document.getElementById("message").value == '') {
document.getElementById("errorMessage").innerHTML = 'the field should not be empty!';
return false;
}
else {
document.getElementById("errorMessage").innerHTML = '';
return true;
}
};
}
window.onload = function () {
prepareEventHandlers();
}
then the html code :
<div id="form-content" class="modal hide fade in" style="display: none;">
<div class="modal-body">
<form class="contact" name="contact" >
<label class="label" for="message">Enter a Message</label><br>
<textarea id="message" name="message" class="input-xlarge"></textarea>
<p><span id="errorMessage"></span></p>
</form>
</div>
<div class="modal-footer">
<input class="btn btn-success" type="submit" value="Send!" id="btnsubmit">
No!
</div>

TypeError: document.getElementById(...) is null document.getElementById("contact").onsubmit = function () {
Any Idea?
Edit:
OK I add id="contact" to my form so the error is gone but now the popup form is displyaed but when I try to click send with empty or not empty value nothing is happened...
just close </form> after <input class="btn btn-success" type="submit" value="Send!" id="btnsubmit">
and change html form id to contact

What the script does is hide the input element and show the "thanks message".
But prior to this I need it to validate if input emailfield is validated, and show the "thanks message" only if that happens.
Thanks!
var nextStep = document.querySelector('#nextStep');
nextStep.addEventListener('click', function(e) {
e.preventDefault()
// Hide first view
document.getElementById('my_form').style.display = 'none';
// Show thank you message element
document.getElementById('thank_you').style.display = 'block';
});
<form class="row row-cols-lg-auto g-2 align-items-center justify-content-end">
<div class="col-12" id="my_form">
<input id="emailfield" type="email" class="form-control" placeholder="Ingresa tu Email" required="required">
</div>
<div class="col-12" id="thank_you" style="display: none;">
Gracias por subscribirse!
</div>
<div class="col-12">
<button type="submit" class="btn btn-primary-soft m-0" name="subscribirse" id="nextStep">Subscribirse</button>
</div>
</form>
var nextStep = document.querySelector('#nextStep');
nextStep.addEventListener('click', function (e) {
e.preventDefault()
let inputEmail = document.querySelector('#emailfield')
if (/.*\#.*\..*/.test(inputEmail.value)) {
// validation passed
// Hide first view
document.getElementById('my_form').style.display = 'none';
// Show thank you message element
document.getElementById('thank_you').style.display = 'block';
} else {
// validation not passed
}
});
Instead of this regexp you can use any that you want

You have to prevent your form from submitting first before you can run custom code, or else your form will submit before your code runs. This can be done by using e.preventDefault(). For example:
$("form").submit(function (e) {
e.preventDefault();
...
}
I am trying to validate the form with id's username and initial_password: The HTML portion is as:
<form name="myform" action="includes/logincontrol.php" method="POST" onsubmit="return validateForm()">
<div class="form-group"> <!-- User ID Field -->
<label id="user_name_error" >User ID:</label>
<input class="form-control" id="username" type="text" onfocusout ="validateUserName()"/>
</div>
<div class="form-group"> <!-- Password Field -->
<label id="password_error">Password: </label>
<input class="form-control" id="initial_password" type="password" onfocusout ="validatePassword()"/>
</div>
<div class="form-group"> <!-- Register -->
<p id="submit-error"></p>
<hr/>
<button class="btn btn-primary" id="login" type="submit">Login</button>
<input class="btn btn-danger" type="reset" value="Reset" onClick="clearfunc()"/>
<hr/>
<button type="button" class="btn btn-success" onclick="window.location.href = 'register_user.php'">Register</button>
<button type="button" class="btn btn-warning" onclick="window.location.href = 'changepw.php'">Change Password</button>
</div>
</form>
Java Script:
function validateUserName() {
var user_name_entered = document.getElementById('username').value;
if (user_name_entered.length === 0) {
producePrompt('User empty?', 'user_name_error', 'red');
document.getElementById('login').disabled = true;
return false;
}
producePrompt('User Name OK!', 'user_name_error', 'green');
document.getElementById('login').disabled = false;
return true;
}
function validatePassword() {
var password_entered = document.getElementById('initial_password').value;
if (password_entered.length === 0) {
producePrompt('Password empty?', 'password_error', 'red');
document.getElementById('login').disabled = true;
return false;
}
producePrompt('Password Entered!', 'password_error', 'green');
document.getElementById('login').disabled = false;
return true;
}
function producePrompt(message, promptLocation, color) {
document.getElementById(promptLocation).innerHTML = message;
document.getElementById(promptLocation).style.color = color;
}
I am unable to get the elements in $_POST array. Please help
You have to put name at inputs, to access them with $_POST.
<input name="usernameInput" class="form-control" id="username" type="text" onfocusout ="validateUserName()"/>
<?php
$username = $_POST['usernameInput'];
?>
If you want to see if the form is submited put a name in the type submit input and try this:
if (isset($_POST['submitButton']) {
$username = $_POST['usernameInput'];
#..etc
}

Put a hidden input in your form. before submitting in your js, fill it with a new key according to time.
in your php file check if key is duplicate or not? or even if its filled?
Because js fill this input after clicking the submit button, every time you submit your form you have a new key! If you refresh the form, you're gonna send the previous value again.
For your problem then best practice recommended is to use jquery ajax requests.
Firstly if you pretend to use "submit" element then do following,
$(".form-vertical").submit(function(e) {
e.preventDefault();
//send ajax with your form data. Ample examples on SO already.
$.ajax(.....);
});
Other option we would recommend is to avoid using 'submit' behavior at first place for requirement you have.
1. Use button elements instead of submit element.
2. Attach click event on button. i.e. in your case 'send'.
3. On click, send ajax as described above. This will avoid doing things like onsubmit="return sendEmail();" you had to do.
4. Also following is not required as well,
$(".form-vertical").submit(function(e) {
e.preventDefault();
as it will be done as follows,
$("button#buttonId").click(function(e) {
// your ajax call.....
}
been looking through previously asked questions but can't find much help.
I have the following html code that sends through a data-id to the following modal, when the user submits the form i have created a ('#edit-form').submit function which needs to send through the previously mentioned data-id.
Here's my code
Button to Open Modal >>
<button type="button" class="edit-group" title="Edit Group" data-id="<?php echo $group->id ?>" data-name="<?php echo $group->groupName ?>">Edit Group</button>
Form inside modal:
<form class="form-horizontal" id="edit-template-form">
<div class="modal-body">
<div class="form-group">
<label for="edit-group-name" class="col-sm-2 control-label">Group name</label>
<div class="col-sm-10">
<input type="text" name="groupName" class="form-control" id="edit-template-name" placeholder="New Group Name">
</div>
</div>
<input type="hidden" id="edit-template-id">
</div>
<div class="modal-footer">
<button type="button" class="md-close" data-dismiss="modal">Cancel</button>
<button type="submit" class="btn btn-primary btn-flat">Save Changes</button>
</div>
</form>
Jquery
$('#edit-template-form').submit(function (e) {
e.preventDefault();
var data = {
id: $(this).parent().val($(this).data('id')),
name: $('#edit-template-name').val()
};
console.log(data);
return false;
});
this keyword refers to data object itself not #edit-template-form. So store the variable this before using it like below:
$('#edit-template-form').submit(function (e) {
e.preventDefault();
var form = $(this);
var data = {
id: form.parent().val(form.data('id')),
name: $('#edit-template-name').val()
};
console.log(data);
return false;
});
