Adding a search field in html form - javascript

I have a basic Html form . I am trying to build a search bar that would highlight a label which matches that content . Here is my JSFiddle Link. The search is not perfect. For eg when trying to search keyword First it highlights all the labels that starts with F.
$("#searchbox").keydown(function() {
var content = $('#searchbox').val();
if(content!== ""){
if ($("label:contains('"+content+"')"))
{
$("label:contains('"+content+"')").addClass("highlight");
} else {
$("label:contains('"+content+"')").removeClass("highlight");
}
}
else{
$("label:contains('"+content+"')").removeClass("highlight");
}
});
.highlight{
border: red;
background-color: yellow;
}

<div class="container">
<br/>
<input id="searchbox" placeholder="Enter your search term">
<h2>Vertical (basic) form</h2>
<form action="/action_page.php">
<div class="form-group">
<label for="email">Email:</label>
<input type="email" class="form-control" id="email" placeholder="Enter email" name="email">
</div>
<div class="form-group">
<label for="pwd">Password:</label>
<input type="password" class="form-control" id="pwd" placeholder="Enter password" name="pwd">
</div>
<div class="checkbox">
<label><input type="checkbox" name="remember"> Remember me</label>
</div>
<div class="form-group"><label for="first">First</label><input type="text"></div>
<div class="form-group"><label for="second">Second</label><input type="text"></div>
<div class="form-group"><label for="third">Third</label><input type="text"></div>
<div class="form-group"><label for="fourth">Fourth</label><input type="text"></div>
<div class="form-group"><label for="fifth">Fifth</label><input type="text"></div>
<button type="submit" class="btn btn-default">Submit</button>
</form>
I am new to JQuery and I know this is not a clean code. This is what I tried by referring other examples.

You could iterate through label elements on keyup and check if the text includes the value of the search field and based on that add or remove a class.
$("#searchbox").keyup(function() {
const content = $('#searchbox').val().toLowerCase();
const labels = $('label');
labels.each(function() {
const check = $(this).text().toLowerCase().includes(content)
if (content.length && check) $(this).addClass('highlight')
else $(this).removeClass('highlight')
})
});
.highlight {
border: red;
background-color: yellow;
}

How to remove the box-shadow from the Jquery validator error message?

I have the following form:
<form id="form-email" class="ps-4 contact-form" autocomplete="off">
<div class="row">
<div class="form-group col-md-6">
<input class="form-control contact-input" name="fname" type="text" placeholder="Name"/>

</div>
<div>
<button class="btn btn-lg btn-outline-warning contact-input-button" type="submit" style="float:right;">
Send e-mail
</button>
</div>
</form>
The Jquery validator:
$(function(){
$("#form-email").validate({
errorClass:"invalid-input",
rules:{
fname:"required",
femail:"required",
fsubject:"required",
fmessage:"required"
},
submitHandler: function() { alert("Success, your e-mail has been submited!") }
});
});
The CSS errorClass:
.invalid-input {
box-shadow: 0 3px 0 0 rgb(255 0 0) !important;
color: red;
}
The page:
How can I keep the red box shadow in the input box but remove it from the label? Jquery is adding the errorClass to both input and label elements.
Is there a way to handle 2 errorClasses? one for the input and another for the label?
Just use input.invalid-input, textarea.invalid-input selector, if you want target inputs and textarea only.
$(function(){
$("#form-email").validate({
errorClass:"invalid-input",
rules:{
fname:"required",
femail:"required",
fsubject:"required",
fmessage:"required"
},
submitHandler: function() { alert("Success, your e-mail has been submited!") }
});
});
input {
margin-bottom: 5px;
}
input.invalid-input, textarea.invalid-input {
box-shadow: 0 3px 0 0 rgb(255 0 0) !important;
color: red;

Client Side Form Validation not happening + can't edit form elements

I am not able to perform client-side form validation. It's a simple check. I wanna make sure that the passwords are the same. This is the javascript code snippet that I am using for the same.
$(document).ready(function(e) {
$("#reg-form").submit(function(event)) {
let $password = $('#password');
let $confirm = $('#confirmPass');
let $error = $('#confirmError');
if ($password.val() === $confirm.val()) {
return true;
} else {
$error.text("Passwords don't match");
event.preventDefault();
}
}
})
Although, I don't think the problem is in the javascript code because I tried to style some items in the form and that didn't work either so I think it's an HTML issue. However, I can't pinpoint the issue. This is my HTML Code.
<div class="d-flex justify-content-center">
<form class="reg-form" id="reg-form" enctype="multipart/form-data" action="register.php" method="post">
<div class="form-row">
<div class="col">
<input type="text" name="firstName" id="firstName" class="form-control" value="" placeholder="First Name*" required>
</div>
<div class="col">
<input type="text" name="lastName" id="lastName" class="form-control" value="" placeholder="Last Name*" required>
</div>
</div>
<div class="form-row my-4">
<div class="col">
<input type="email" name="email" id="email" class="form-control" value="" placeholder="Email*" required>
</div>
</div>
<div class="form-row my-4">
<div class="col">
<input type="password" name="password" id="password" class="form-control" value="" placeholder="Password*" required>
</div>
</div>
<div class="form-row my-4">
<div class="col">
<input type="password" name="confirmPass" id="confirmPass" class="form-control" value="" placeholder="Confirm Password*" required>
<small id="confirmError" class="text-danger"></small>
</div>
</div>
<div class="form-check form-check-inline">
<input type="checkbox" name="agreement" class="form-check-input" value="" required>
<label for="agreement" class="form-check-label font-ubuntu text-black-50"> I agree to the Terms and Conditions*</label>
</div>
<div class="submit-btn text-center my-5">
<button type="submit" class="btn btn-warning rounded-pill text-dark px-5" name="button">Continue</button>
</div>
</form>
The following is the CSS code that I tried to work with.
#reg-form input[type="text"],
#reg-form input[type="email"] {
border-radius: unset;
border: none;
border-bottom: 1px solid var(--color-border);
font-family: var(--font-ubuntu);
font-size: 18px;
}
I found some issues with the JavaScript markup, had a few closing brackets missing and closing parentheses declared too early in the code; but your code itself looks like it works with the correct markup on the JS, please see below:
$(document).ready(function() {
$("#reg-form").submit(function(e) {
let $password = $('#password');
let $confirm = $('#confirmPass');
let $error = $('#confirmError');
if ($password.val() === $confirm.val()) {
console.log(true);
return true
} else {
e.preventDefault();
$error.text("Passwords don't match");
}
})
})
#reg-form input[type="text"],
#reg-form input[type="email"] {
border-radius: unset;
border: none;
border-bottom: 1px solid var(--color-border);
font-family: var(--font-ubuntu);
font-size: 18px;
}

bootstrap custom validation is not showing up specific field on submission of the form

I want to know how to make the bootstrap custom validation also show the specific field where the form is not filled.
You can observe the normal form shows or goes to the specific field which is not filled when the form is submitted
where bootstrap custom validation doesn't do that.
This is the code with out bootstrap custom validation

If you remove novalidate="" from <form class="needs-validation was-validated" novalidate=""> you get the same result as without Bootstrap validation.
novalidate prevents the browser to validate the form so you can apply the custom behaviour of Bootstrap.
If you want to add scroll to id after the validation I suppose you have to do by yourself or check if there is such config in the library you are using.
I have updated the code by using some JavaScript code.
And it's working. :)
// Example starter JavaScript for disabling form submissions if there are invalid fields
(function() {
'use strict';
window.addEventListener('load', function() {
// Fetch all the forms we want to apply custom Bootstrap validation styles to
var forms = document.getElementsByClassName('needs-validation');
// Loop over them and prevent submission
var validation = Array.prototype.filter.call(forms, function(form) {
form.addEventListener('submit', function(event) {
if (form.checkValidity() === false) {
event.preventDefault();
event.stopPropagation();
var invalidOptions = document.querySelectorAll(
".form-control:invalid");
invalidOptions.forEach(function(element) {
element.parentNode.childNodes.forEach(function(node) {
if (node.className == 'valid-feedback') {
node.className = 'invalid-feedback';
node.innerText =
'Please choose a Gender';
}
});
});
$('html, body').animate({
scrollTop: $(invalidOptions[0]).offset().top
}, 2000);
}
form.classList.add('was-validated');
}, false);
});
}, false);
})();

Exposing form input when previous is selected or filled in

This will most likely need to involve javascript, which I know almost nothing about so please bear with me.
I would like to have a regular form, say styled with bootstrap. But I don't want to display the all the fields at once when the page is loaded. Instead I would like to display the first field and continue to display the following fields as the previous fields are focused or have content in them.
<form action="" method="post">
<div class="form-group">
<label for="name">Name</label>
<input type="text" name="name" class="form-control">
</div>
<div class="form-group">
<label for="email">Email</label>
<input type="email" name="email" class="form-control">
</div>
<div class="form-group">
<label for="website">Website</label>
<input type="text" name="website" class="form-control">
</div>
<div class="form-group">
<label for="message">Message</label>
<textarea name="message" class="form-control" rows="5"></textarea>
</div>
</form>
In this example only "Name" would show up, when the page loads, then when it is focused then the "Email" field would show up.
Any ideas would be great, thanks!
Just hide all elements in the form except for the first one, listen for changes on the form and display the next element relating to the last changed element (the event.target).
Example (which is definitley improvable):
$(".form-group:not(:first-child)").hide();
$("form").on("change keypress paste", function (event) {
$(event.target).parent().next().show();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form action="" method="post">
<div class="form-group">
<label for="name">Name</label>
<input type="text" name="name" class="form-control">
</div>
<div class="form-group">
<label for="email">Email</label>
<input type="email" name="email" class="form-control">
</div>
<div class="form-group">
<label for="website">Website</label>
<input type="text" name="website" class="form-control">
</div>
<div class="form-group">
<label for="message">Message</label>
<textarea name="message" class="form-control" rows="5"></textarea>
</div>
</form>
You could use JQuery to remove a hidden class on input focus.
Run the code snippet or check out the CodePen Demo:
$(document).ready(function() {
$("input").focus(function() {
$(this).parent(".form-group").next().removeClass("hidden");
});
});
.hidden {
display: none;
}

Change the task of a button placed in the footer of modal

I have a modal. In the header of the modal I have title which is login. And in the body I have a login form and in the footer I have login button.
After the login button I have a hyper text for those who wants to create account which by clicking on it the login form disappear and the register form appears.
Is there any possibility that I can use the same button for logging in to register. (In the simplest word is it possible to use the same button in 2 different forms or if I can't, how can I add a button to the footer and make it act as the submit button of the reiteration form)

Here are some boilerplates that you can try with....(your part is just basically determining which form is active...)
$(document).ready(function(){
$('#submitbtn').click(function(e){
e.preventDefault();
var form=$('#currentForm').val();
if(form=="login")
{
alert('submit to login');
}
else
{
alert('submit to register');
}
});
$('#btnchange').click(function(){
var form=$('#currentForm').val();
if(form=="login")
{
$('#currentForm').val('register');
$('#registration-form').show();
$('#login-form').hide();
}
else
{
$('#currentForm').val('login');
$('#registration-form').hide();
$('#login-form').show();
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.1/jquery.min.js"></script>
<form method="post" action="register.php" name="registration-form" id="registration-form" style="display:none;">
<label for="name">Name:</label>
<input type="text" name="usename"><br/>
<label for="emailid">Email ID:</label>
<input type="text" name="emailid"><br/>
<label for="password">Password :</label>
<input type="password" name="password">
</form><br/><br/>
<form method="post" action="login.php" name="login-form" id="login-form">
<label for="emailid">Email ID :</label>
<input type="text" name="emailid">
<label for="password">Password :</label>
<input type="password" name="password">
</form>
<input type="hidden" value="login" id="currentForm"/>
<input type="button" value="Submit" name="submitbtn" id="submitbtn">
<input type="button" value="Toggle Form" id="btnchange"/>
Just so I understand your question a little bit better, the basic idea of what you're trying to do is:
Single page modal, one form. Take user text input, check for existing user with that info, create new user if none exists?
