I was trying to make a registration form using HTML, Bootstrap and JavaScript.
I am able to get the error message when a field is left empty, but the error message vanishes just after showing up. I don't know what am I doing wrong
function checkValidation() {
var firstName = document.getElementById('firstName').value;
if (firstName == "") {
console.log("enter");
document.getElementById('firstNameErrorMessage').innerHTML = "please enter";
} else {
console.log("done");
}
}
<div class="container-fluid">
<div class="container">
<h2>Registration Form</h2>
<form class="form-horizontal" name="myForm">
<div class="form-group">
<label class="control-label col-sm-2" for="firstName">
First Name
</label>
<div class="col-sm-10">
<input type="text" name="firstName" class="form-control" id="firstName" placeholder="Enter your First Name" name="firstName">
<div class="col-sm-12">
<p id="firstNameErrorMessage"></p>
</div>
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<button type="submit" class="btn btn-default" onclick="checkValidation()">Submit</button>
</div>
</div>
</form>
</div>
</div>
You will need to use preventDefault in order to make it work as intended:
<div class="container-fluid">
<div class="container">
<h2>Registration Form</h2>
<form class="form-horizontal" name="myForm">
<div class="form-group">
<label class="control-label col-sm-2" for="firstName">
First Name
</label>
<div class="col-sm-10">
<input type="text" name="firstName" class="form-control" id="firstName" placeholder="Enter your First Name" name="firstName">
<div class="col-sm-12">
<p id="firstNameErrorMessage"></p>
</div>
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<button type="submit" class="btn btn-default" onclick="checkValidation(event)">Submit</button>
</div>
</div>
</form>
and
function checkValidation(e) {
e.preventDefault();
var firstName = document.getElementById('firstName').value;
if (firstName == "") {
console.log("enter");
document.getElementById('firstNameErrorMessage').innerHTML = "please enter";
} else {
console.log("done");
}
}
Have a look here for some preventDefault questions:
How and when to use preventDefault()?
What's the difference between event.stopPropagation and event.preventDefault?

When user click submit, it should open http://127.0.0.1:5000/default/+UserInput. But the giveme() function returns "?keyword=UserInput" instead of "UserInput". How can I get a correct URL?
<form id="myform" class="form-horizontal" action="http://127.0.0.1:5000/default/" +

</form>
<script>
function giveme(){
document.getElementById("keyword").value;

Here is a function that gets what you want:

document.getElementById("keyword").value = params.get('keyword');

I'm a novice at Laravel. How can I add new text input fields with the button and add data in each field separately? Add or plus button or whatever.
Below my code, which allows you to enter the sledge, but only in one field, in addition you have to separate the words with a comma.
<div class="card-body">
<form method="post" action="{{route('randomizeTeam.store')}}">
{{ csrf_field() }}
<div class="form-group">
<label for="players">Add player names</label>
<input type="text" class="form-control" name="players">
</div>
<div class="form-group">
<label for="teams">Add team names</label>
<input type="text" class="form-control" name="teams">
</div>
<div class="form-group">
<button type="submit" class="btn btn-info">Send</button>
</div>
</form>
</div>
This is how you can do it in a simple way
$(function(){
var more_fields = `
<div class="form-group">
<label for="players">Add player name</label>
<input type="text" class="form-control" name="players[]">
</div>
<div class="form-group">
<label for="teams">Add team name</label>
<input type="text" class="form-control" name="teams[]">
</div>
`;
$('#add-more-field').on('click', (function (e) {
e.preventDefault();
$(".input-fields").append(more_fields);
}));
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="card-body">
<form method="post" action="">
{{ csrf_field() }}
<div class="input-fields">
<div class="form-group">
<label for="players">Add player name</label>
<input type="text" class="form-control" name="players[]">
</div>
<div class="form-group">
<label for="teams">Add team name</label>
<input type="text" class="form-control" name="teams[]">
</div>
</div>
<div class="form-group">
<button id="add-more-field" class="btn btn-secondary btn-sm">add more</button>
</div>
<div class="form-group">
<button type="submit" class="btn btn-info">Send</button>
</div>
</form>
</div>
And in your controller, you will do something like this
foreach($request->get('players') as $i => $player) {
YourModel::create([
'player' => $player,
'team' => $request->get('teams')[$i]
]);
}
I am intend to use javascript to submit the form. Before I want to submit the form, I need to validate my form.
The following is my code :
alert("OP Please edit me to add the validation script code, cdn link or something. Add code that triggers the validation.");
function validateForm1() {
$("#addMapForm").validate();
$('#addMapForm').valid();
console.log($('#addMapForm').valid());
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-validate/1.19.0/jquery.validate.min.js"></script>
<form enctype="multipart/form-data" action="/Admin/AddMap" method="post" id="addMapForm">
<div>
<br />
<br />
<div class="col-md-12">
<div class="form-group">
<label>Location Name *</label>
<input class="form-control" required />
</div>
</div>
<div class="col-md-12">
<div class="form-group">
<label>Unit/ Floor Number</label>
<input class="form-control" />
</div>
</div>
<div class="col-md-12">
<div class="form-group">
<label>Address*</label>
<textarea class="form-control" style="height:100px" required></textarea>
</div>
</div>
<div class="col-md-12">
<div class="form-group">
<label>Town/ City *</label>
<input class="form-control" required />
</div>
</div>
<div class="col-md-12">
<div class="form-group">
<label>Zip Code*</label>
<input class="form-control" required/>
</div>
</div>
</div>
</form>
You are missing names on the inputs. A form will only submit named controls and validation plugin won't validate anything without a name
The required fields work fine once you add them
$("#addMapForm").validate();
$("#addMapForm").valid();
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-validate/1.19.0/jquery.validate.min.js"></script>
<form enctype="multipart/form-data" action="/Admin/AddMap" method="post" id="addMapForm">

<br />
<br />
<div class="col-md-12">
<div class="form-group">
<label>Location Name *</label>
<input name="location" class="form-control" required />
</div>
</div>
<div class="col-md-12">
<div class="form-group">
<label>Unit/ Floor Number</label>
<input name="unit" class="form-control" />
</div>
</div>
<div class="col-md-12">
<div class="form-group">
<label>Address*</label>
<textarea name="address" class="form-control" style="height:100px" required></textarea>
</div>
</div>
<div class="col-md-12">
<div class="form-group">
<label>Town/ City *</label>
<input name="city" class="form-control" required />
</div>
</div>
<div class="col-md-12">
<div class="form-group">
<label>Zip Code*</label>
<input name="zip" class="form-control" required/>
</div>
</div>
</div>
<button>Submit</button>
</form>
I assume you are using this: https://jqueryvalidation.org/validate/
Have you implemented the rules of validation for other elements?
rules (default: rules are read from markup (classes, attributes, data))
So either you have those defined in HTML or you need to define them inside validate function called before you called .valid().
Here is an examle:
$("#myform").validate({
rules: {
// simple rule, converted to {required:true}
name: "required",
// compound rule
email: {
required: true,
email: true
}
}
});
In short for more precise help we need all the relevant code or fiddle, plunker a demo showing the example of the problem you are facing.
Try this solution.
$('.form-control').each(function() {
$(this).validate();
$(this).valid();
}
I tried to use the following js to validate all my form, however i know the following code is not the best answer, it only able to show the error message on the first input element.
I am welcome to anyone to post better answer than this.
function validateForm() {
var result = true;
$("#addMapForm").each(function () {
$(this).find(':input').each(function () {
if ($(this).valid() == false) {
result = false;
return;
}
});
});
return result;
}
I gave your form inputs some name attributes. Not sure if you added the actual code to your page, so I did so here. I added a button to trigger just for a demo. I added the simplest bit of CSS.
$("#validateme").on('click', function() {
console.log("validating");
let Validator = $("#addMapForm").validate();
Validator.form();
console.log(Validator.valid());
});
.error { color:red}

Here is my javascript code. The commented line works:
$("#regForm").submit(function(event) {
// event.preventDefault()
password = $("#inputPassword3")
login = $("#inputEmail3")
user_instance = 0
$.ajax({
url: "{{ url_for('get_users') }}",
method: 'POST'
}).done(function(data) {
data.forEach(function(item) {
if (item.username == login.val() || item.mail == login.val()) {
user_instance = item
}
})
pass_arr = sjcl.hash.sha256.hash(password.val())
hash = sjcl.codec.hex.fromBits(pass_arr)
console.log(hash, user_instance.passwd)
if (hash != user_instance.passwd) {
event.preventDefault()
console.log("+")
password.attr("style", "border:#f00 solid 1px")
password.attr("placeholder", "Wrong password")
}
event.preventDefault() is not working here:
<div id="regForm">
<form class="form-horizontal" method="POST" action="{{ url_for('login') }}">
<div class="form-group">
<label for="inputEmail3" class="col-sm-2 control-label">Email/Login</label>
<div class="col-sm-10">
<input type="imput" class="form-control" id="inputEmail3" placeholder="Email/Login" name="email">
</div>
</div>
<div class="form-group">
<label for="inputPassword3" class="col-sm-2 control-label">Password</label>
<div class="col-sm-10">
<input type="password" class="form-control" id="inputPassword3" placeholder="Password" name="password">
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<div class="checkbox">
<label>

</div>
</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<button type="submit" class="btn btn-default" name="sign-in">Sign in</button>
</div>
</div>
</form>
It submits form anyway, even though color of form changing, why is that? When uncommented preventDefault() is working as should be
Try this
$('body').on('submit', 'YOUR-ID' ,function(event) {}
I have the following form. I want to validate the email field .it should only contain for domain name "#somename.com " when the user clicks submit.
The mail should only be validated when the check box is clicked to show the email field.
If the email is invalid i want to prevent submission
<form class="form-horizontal" id="rForm" data-toggle="validator" role="form">
<div class="form-group">
<div class="col-xs-offset-3 col-xs-8">
<label class="checkbox-inline col-xs-10">
<input type="checkbox" ID="chkbx"> Email
</label>
</div>
</div>
<div class="form-group email">
<div class="col-xs-offset-3 col-xs-8">
<div class="col-xs-8">
<input type="text" class="form-control " placeholder="Enter email">
</div>
</div>
</div>
<div class="form-group">
<div class="col-xs-offset-3 col-xs-8">
<input type="reset" class="btn btn-default" id="rset" value="Reset">
<input type="submit" class="btn btn-primary" id="submit" value="Submit">
</div>
</div>
</form>
JS
$("#submit").on('keypress click', function(e){
e.preventDefault();
$('#chkbx').hide();
$('#chkbx').click(function () {
// This will show / hide your element accordingly
$('.email').toggle();
});
});
Checkout JavaScript RegEx to determine the email's domain (yahoo.com for example). You can use that and augment your example:
$('#chkbx').click(function() {
// This will show / hide your element accordingly
$('.email').toggle();
});
$("#submit").on('click', function(e) {
e.preventDefault();
if ($('#chkbx').is(':checked')) {
// https://stackoverflow.com/questions/3270185/javascript-regex-to-determine-the-emails-domain-yahoo-com-for-example
console.log(/#testdomain.com\s*$/.test($('#email_input').val()));
}
});

Use the following function to test for your email.
EDIT:
You first need to add a name= and id= to your email input field.... So what you want to do is:
<input type="text" class="form-control " placeholder="Enter email" name="email" id="email">
and then do:
function testEmail(string) {
var regex = /.+#somename.com$/i;
return regex.test(string);
}
//testEmail("nope#test.com"); // false
//testEmail("what#somename.com.other"); //false
//testEmail("yeah#somename.com"); //true
//testEmail("#somename.com"); // false
$('form').submit(function(e){
var values = $('form').serialize();
if(!testEmail(values.email))
e.preventDefault();
// your submission code goes here.
})
