I've written some jQuery to validate my Bootstrap forms, however I'm having a few issues.
Firstly, I want a red outline to appear if the user clicks off the input field without typing anything in: JSFiddle example here. In this example I'm using the Bootstrap Validator plugin, however I want to imitate this effect without using the plugin.
Second, and linked to the issue I just mentioned, the green outline only appears once the user clicks the submit button, thus the user only sees it for half a second or so before they are redirected, making it a little pointless. Again, this would be solved by having an error/success outline appear once the user clicks off the input. If anyone could help me out it would be greatly appreciated.
This is the code I have so far:
HTML:
<form id="auth_form" action="action.php" method="post">
<div class="form-group has-feedback" name="auth_code" id="auth_code">
<label for="auth_code" class="control-label">
Authorisation Code</label>
<input class="form-control" id="auth_code_input" name="auth_code_input" type="password">
<span class="form-control-feedback glyphicon" id="iconBad"></span>
</div>
<div class="form-group">
<div>
<button class="btn btn-info" name="submit" type="submit" id="submit">Submit</button>
</div>
</div>
</form>
jQuery:
$(document).ready(function() {
$('#auth_form').on('submit', function(e) {
var auth_code = $('#auth_code_input').val()
if (auth_code=="") {
$('#auth_code').addClass('has-error');
$('#iconBad').removeClass('glyphicon-ok').addClass('glyphicon-remove');
e.preventDefault();
} else {
$('#auth_code').removeClass('has-error').addClass('has-success');
$('#iconBad').removeClass('glyphicon-remove').addClass('glyphicon-ok');
}
})
})

});
function ValidateInput(){

I am using a Wordpress theme that unfortunately is duplicating the header HTML for desktop, mobile and tablet. As a result, a login form I have appears to be submitting multiple times even though "Login" is only clicked once.
Here is the HTML for the form:
<div id="user-login">
<div class="com_row">
<div class="com_panel_body">
<div id="error_message91" class="com_alert com_alert_danger" style="display: none;">
</div>
<form method="post" id="validation_form83">
<input type="hidden" name="login_form_flag" value="1">
<div class="login-username">
<label for="email" class="main_label">Email Address</label>
<input id="email68" type="email" name="email" required="required">
</div>
<div class="login-password">
<label for="password" class="main_label">Password:</label>
<input id="password82" type="password" name="password" required="required">
</div>
<ul class="login-links" style="margin-top:-30px"><li>Forgot Password?</li></ul>
<div class="login-submit" style="margin-top:-20px">
<input type="submit" value="Login"></div>
<div style="padding-top:20px"><a class="button green small borderd-bot" href="/client_account">Register</a></div>
</form>
</div>
</div>
</div>
Here is the relevant JS:
$("[id^='validation_form']").each(function(i) {
//necessary because there are 3 form duplicates on the page, so this button works on all
jQuery(document).on("submit", this, SubmitValidationForm);
});
function($) {
SubmitValidationForm = function (event) {
event.preventDefault();
var formk = "#"+event.target.id;
var k = $(formk).serialize();
k += "&action=wcap_requests&what=validate_login";
jQuery("input[type=email]",formk).prop("disabled", true);
jQuery("input[type=password]",formk).prop("disabled", true);
jQuery("input[type=submit]",formk).prop("disabled", true).val(WCAP_Working_text);
var childf = $(formk).closest('div','.com_alert').children( ".com_alert");
$(childf).hide();
var login_form_flag = jQuery("input[name=login_form_flag]",formk).val();
jQuery.post(wcap_ajaxurl, k, function (data) {
data = JSON.parse(data);
console.log(data);
if (data.status === "OK") {
//== if client login through wcap login form
if (login_form_flag === '1'){
window.location.href = client_area_url;
}
else {
if (redirect_login !== "0") {
window.location.href = redirect_login;
} else {
window.location.reload();
}
}
}
else {
jQuery("input[type=email]",formk).prop("disabled", false);
jQuery("input[type=password]",formk).prop("disabled", false);
jQuery("input[type=submit]",formk).prop("disabled", false).val('Login');
$(childf).html(data.message).show();
}
});
};
};
The problem is because there are 3 duplicate forms on the page HTML (with only 1 visible to the user), the SubmitValidationForm function is called 3 times every time. The issue is pronounced when there is a valid login submitted, but the error box still appears saying invalid email after a few seconds (even though the login is actually correct and the user gets automatically redirected properly to the client area ). This error seems caused by the fact the SubmitValidationForm function is called 2 subsequent times after the first 'valid' submission which makes it think it's invalid, when it's not... the interesting thing is it doesn't seem caused by the other duplicate forms in the HTML, as the form ID attribute that I display in browser console shows only the 'valid' form being submitted (albeit multiple times -- perhaps because of the jquery.on() for each function).
Any ideas how to fix?
Thanks!
I figured out the issue. If anyone else is looking at this in future the issue was with respect to the 'on' function, it was referencing the 'document' before instead of 'this'. So it should be changed to:
$("[id^='validation_form']").each(function(i) {
jQuery(this).on("submit", this, SubmitValidationForm);
});
I have an HTML form that has its elements displayed in various Bootstrap modals. The first modal has a text box input that and a "Next" button to open the next modal. When the "next" button is pressed. I want to check if the text box is empty, and trigger a validation message. The form does not get submitted until the very end. Everything I've tried has not worked so far.
Javascript/jQuery code
$("#add_assistant_next").click(function () {
var textInput = document.getElementById('add_assistant_user');
var text = textInput.value;
if (text === "") {
textInput.setCustomValidity('Please fill out this field.');
textInput.checkValidity();
var form = $('#form_add_assistant');
form.find(':submit').click();
} else {
textInput.setCustomValidity('');
}
});
HTML
<form name="add_assistant" method="post" id="form_add_assistant">
<div class="modal-body">
<div class="step">
<span class="fas fa-arrow-right choose-arrow mr-1"></span>1. Choose a user to add
</div>
<div class="pl-3 pt-1">
<div>
<input type="text" id="add_assistant_user" name="add_assistant[user]" required="required" placeholder="UCInetID or UCI email address" class="mr-0 form-control" />
<button type="button" id="add_assistant_next" name="add_assistant[next]" data-toggle="modal" data-target="#add-user-modal" class="btn btn-outline-secondary btn">Look up user</button>
</div>
<input type="hidden" name="user_search_route" value="/courseSpace/20900/listAssistantEnrollment">
</div>
</div>
... form continues in other modals
Your JS code is probably fighting with Bootstrap for control of that button. To get around that, and have your validation, you could try modifying your code to have a middle step / temporary button to help with validation first before actually submitting. So something like this:
Javascript/jQuery code
$("#my_temp_button").click(function () {
var textInput = document.getElementById('add_assistant_user');
var text = textInput.value;
// Might also want to handle null and undefined cases?
if (text === "" || text === undefined || text === null) {
// I'm assuming if it's empty, it doesn't pass validation,
// so we just display this warning and wait for the user to fix it:
textInput.setCustomValidity('Please fill out this field.');
} else {
// it's not empty so validate:
if (textInput.checkValidity()) {
// it passed validation, so ok to submit.
// call the real button:
$('#add_assistant_next').click();
// do you need this?
var form = $('#form_add_assistant');
form.find(':submit').click();
} else {
// it failed validation, so display another error?
textInput.setCustomValidity('Try again.');
}
}
});
HTML:
<form name="add_assistant" method="post" id="form_add_assistant">
<div class="modal-body">
<div class="step">
<span class="fas fa-arrow-right choose-arrow mr-1"></span>1. Choose a user to add
</div>
<div class="pl-3 pt-1">
<div>
<input type="text" id="add_assistant_user" name="add_assistant[user]" required="required" placeholder="UCInetID or UCI email address" class="mr-0 form-control" />
<!-- Feel free to change the id name. This is the button the user sees. It's only purpose is to give your function above full control to it and prevent Bootstrap from touching it and jumping to the next modal without having the user fix the validation failure first: -->
<button type="button" id="my_temp_button" class="btn btn-outline-secondary btn">Look up user</button>
<!-- Hide the real button from the user: -->
<div style="display:none">
<button type="button" id="add_assistant_next" name="add_assistant[next]" data-toggle="modal" data-target="#add-user-modal" class="btn btn-outline-secondary btn">Look up user</button>
</div>
</div>
<input type="hidden" name="user_search_route" value="/courseSpace/20900/listAssistantEnrollment">
</div>
</div>
...
Have you tried adding a trap for the submit event itself?
$('#form_add_assistant').submit(function(evt){
//do your validation here
if (validation fails){
return false; // OR, alternatively, `evt.preventDefault()`
}
//form submission will continue if not returned false
});

How to conduct manual form validation via jQuery .submit()
I have several forms on my profile page. Each form has its own submit button. When a user clicks the submit button, I want the button to disappear and show a spinner.
That works fine. The issue that I am running into, is that if the user forgets to fill-out a required field, the button does not return visible. The spinner stays visible. And the page would have to be reloaded.
Jquery is not intercepting the form submission (though I am open to that if it will fix the issue), it is only toggling the spinner and button visibility.
Any help?

$("#social-loading").hide();
$(document).ready(function () {

There are several issues with your code, but the most important one is that you are retrieving required form elements using a required class, which does not seem to be used in your html. Instead, you can retrieve required form elements using something like
$('#formProfile [required]')
which returns all subelements of formProfile which have the required attribute. You have another issue in that the id of the form is hard-coded. Instead of hard-coding it, use the variable $formid.
$($formid + ' [required]')
Try reordering your scripts, do validation first and check if it's pass. Make sure the checkForm returns true if valid.
$("#btn_profile").on("click", function (e) {
if (checkForm('#formProfile', "#btn_profile", "#profile-loading")) {
$("#profile-loading").show();
$("#btn_profile").hide();
}
});
$("#btn_social").on("click", function (e) {
if (checkForm('#formSocialMedia', "#btn_social", "#social-loading")) {
$("#social-loading").show();
$("#btn_social").hide();
}
});
I try to make required a field when button will radio button will be checked.
My jQuery (or JavaScript) are:
$('input#availability_to_work-1').change(function () {
if(this.checked) {
$('input#availability_date_to_work').prop('required', true);
} else {
$('input#availability_date_to_work').prop('required', false);
}
and
$("input[name='availability_to_work']").click(function () {
if ($("input#availability_to_work-1").is(":checked")) {
$(".wpjb-element-input-text.wpjb-element-name-availability_date_to_work").show();
} else {
$(".wpjb-element-input-text.wpjb-element-name-availability_date_to_work").hide();
}
});
My CSS:
.wpjb-element-input-text.wpjb-element-name-availability_date_to_work{display:none}
And HTML:
<input type="radio" value="'od zaraz'" name="availability_to_work" id="availability_to_work-0">
<div class="wpjb-element-input-text wpjb-element-name-availability_date_to_work" style="display: block;">
<label class="wpjb-label">
Data rozpoczęcia pracy </label>
<div class="wpjb-field">
<input id="availability_date_to_work" name="availability_date_to_work" type="text" required=""> </div>
</div>
All works good till moment if someone will check button with 'value="'od daty'"' and then check "od zaraz".
Then someone gets error in panel developer when tries to sumbit a form:
An invalid form control with name='availability_date_to_work' is not focusable.
Could someone help me to fix it?
With checkbox it's work good. Only with radio buttons it doesn't work fine.
Thank you.
I'm trying to create a loading screen for it to appear when the form is being submitted, it works great except on Safari, the problem is that if you were to click enter or submit an alert appears but when you click okay for the alert to go away the loading appears because of the submit event and doesn't go away. I've tried numerous this but i cant seem to figure it out, i'm a beginner in jquery.
To summarize, on safari after alert, loading screen appears when it's not suppose too and doesn't go away.
Preferably I would like for the loading screen to appear only when the form is being submitted. or the alternative is for the loading screen not to show in a safari browser.
<script>
var form = document.getElementById('formID'); // form has to have ID: <form id="formID">
var ua = navigator.userAgent.toLowerCase();
if (ua.indexOf('safari') != -1) {
if (ua.indexOf('chrome') > -1) {
} else {
form.noValidate = true;
form.addEventListener('submit', function(event) { /*listen for form submitting */
if (!event.target.checkValidity()) {
event.preventDefault(); /*dismiss the default functionality*/
alert('Please, fill the form before you submit'); /*error message*/
$("#formID").attr("id", "form");
$(".circularG1").addClass("active");
$(".circularbrg").addClass("active");
}
}, false);
}
}
</script>
<!--loading screen appears while form submit's-->
<script type="text/javascript">
$(document).ready(function() {
$('#formID').submit(function() {
var pass = true; //some validations
if (pass == false) {
return false;
$(".circularG1").addClass('active'); //hides loading if clicked
$(".circularbrg").addClass('active'); // hides loading if clicked
} else {
$(".circularG1, .active").removeClass('active'); //shows loading if clicked
$(".circularbrg, .active").removeClass('active'); // shows loading if clicked
}
});
});
</script>

<input type="submit" name="submit" class="submit">
</form>
The best way to resolve this issue is to remove the alert line altogether and use a different method. For example, add a div inside your form html:
<div id="form-message"></div>
Then in your jQuery, replace the alert line with:
$('#form-message').text('Please, fill the form before you submit');
This is better in terms of usability as actual alerts are rarely (if ever) used on websites these days.
Hope this helps!
