I have a simple form which has has to be accessible. If someone misses a mandatory field, the a error should show on the top of the page where I placed a div tag. Now, after I click the submit button, it should show an error message on the top of page and then have a focus so that the screen reader can read it without refreshing the page. I am just not being able to focus on that error. Any suggestion would be really appreciated.
Thanks
My code looks like this
<!DOCTYPE html>
<html>
<head>
<title>TEST</title>
<script>
function myFunction() {
document.getElementById("errors").innerHTML = "ERROR ON THE FORM";
}
function getfocus() {
document.getElementById("errors").focus();
}
function printnfocus() {
if (myFunction()) {
getfocus();
}
}
</script>
</head>
<body>
<div id="errors"></div>
<fieldset>
<legend>Eligibility</legend> <input type="checkbox" id="citizen"> <label for="citizen">I am a U.S. citizen</label><br>
<input type="checkbox" id="18"> <label for="18">I am a 18 years old</label>
</fieldset>
<p>
<br>
</p>
<form id="sex" name="sex">
<fieldset>
<legend>Sex:</legend> <label for="male">Male</label> <input type="radio" name="sex" id="male" value="male"><br>
<label for="female">Female</label> <input type="radio" name="sex" id="female" value="female"><br>

<br>
</form>
</fieldset>
<p>
<button type="button" onclick="printnfocus()">Submit</button>
</p>
</body>
</html>
You are looking for window.scrollTo(). You can get the location of the errors div with this:
document.getElementById('errors').offsetTop

Hi i have a form containing postal address and billing information. I want to copy postal address to billing information if information is same. I don't understand how i validate if checkbox is checked then copy postal address to billing information textbox.
My code is as follows:
!DOCTYPE html>
<title>My Example</title>
</head>
<body>
<form class="Form1" method="post">
<fieldset>
<legend>Personal Information</legend>
<label>Name
<input type="text" name="customer_name" required>
</label>
<label>Postal Adress
<input type="text" name="PostalAdress">
</label>
<label>Age
<input type="text" name="Age">
</label>
</fieldset>
</form>
<form class="Form2" method="get">
<fieldset>
<legend>Billing Information</legend>
<p>
<label>Billing Information is Same as the Postal Adress?</label></br>
<input type="checkbox" name="choice1">
<p>
<input type="submit" name="submit" value="Submit" onclick="validate()">
</p>
</p>
<p>
<label>Billing Information</label>
<input type="text" name="BillingInformation">
</p>
</fieldset>
</form>
<form class="Form3">
<fieldset>
<legend>Newsletter Subscription</legend>
<input type="radio" name="yes"><label>Yes</label>
<input type="radio" name="No"><label>No</label>
</fieldset>
</form>
<script>
function validate() {
var remember = document.getElementById("choice1");
if (choice1.checked) {
var src = document.getElementById("PostalAdress"),
dst = document.getElementById("BillingInformation");
src.addEventListener('input', function() {
dst.value = src.value;
});
};
</script>
</body>
</html>
Kindly help me what is wrong with my script and how do i do it.
The same with correct HTML syntax and proper JS
const myForm = document.getElementById('my-Form');
myForm.oninput = () =>
{
if (myForm.choice1.checked)
{
myForm.BillingInformation.value = myForm.PostalAdress.value
}
}
myForm.onsubmit = e =>
{
e.preventDefault() // to test the form without real submit
// get response
Array.from(new FormData(myForm),elm=>console.log(elm[0],'->',elm[1]))
}
label {white-space: nowrap;}
.as-console-wrapper {
max-height: 100% !important;
width: 50% !important;
top: 0; left: 50% !important;
}
<form id="my-Form" method="post" >
<fieldset>
<legend>Personal Information</legend>
<label>
Name
<input type="text" name="customer_name" required>
</label>
<label>
Postal Adress
<input type="text" name="PostalAdress">
</label>
<label>
Age
<input type="text" name="Age">
</label>
</fieldset>
<fieldset>
<legend>Billing Information</legend>
<p>
<label>
Billing Information is Same as the Postal Adress?
<input type="checkbox" name="choice1">
</label>
</p>
<p>
<label>Billing Information</label>
<input type="text" name="BillingInformation" />
</p>
</fieldset>
<fieldset>
<legend>Newsletter Subscription</legend>
<label><input type="radio" name="newsLetter" value="yes" checked > Yes </label>
<label><input type="radio" name="newsLetter" value="No" > No </label>
</fieldset>
<p>
<button type="submit" >Submit</button>
<button type="reset" >reset</button>
</p>
</form>
You can do it like this
$(document).ready(function(){
$(("input[name='choice1']").click(function(){
if($(this).is(":checked")){
var postal_address = $("input[name='PostalAdress']")
$("input[name='BillingInformation']").val(postal_address)
}
})
});
jQuery cdn
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
I'm currently working with a contact form plugin through Wordpress and so the outputted HTML and JS looks like the following:
$('.form .form--field label').click(function() {
$(this).parents('.form--field').addClass('form--field--focus');
$('input').filter(':first').focus();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="form--field form--field__firstname">
<label for="firstname" class="form--field__label">First Name</label>
<span>
<input type="text" name="firstname">
</span>
</div>
The design has caused me to get a bit hacky with it but in any event, I'm trying to figure out how to force focus on the respective input whenever the user clicks on a label. At the moment, this is where I'm at with it. If anyone has any input or suggestions, that would be greatly appreciated.
the for attribute on a <label> looks for an id not a name. Example below should work without JavaScript
<div class="form--field form--field__firstname">
<label for="firstname" class="form--field__label">First Name</label>
<span>
<input type="text" id="firstname" name="firstname">
</span>
</div>
Although if you really want to do this with JavaScript/JQuery and not be tied down to using a label you can do it this way using $(this).next().children().focus();
$('.form--field__label').click(function() {
$(this).next().children().focus();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="form--field form--field__firstname">
<label class="form--field__label">First Name</label>
<span>
<input type="text">
</span>
</div>
<div class="form--field form--field__secondname">
<!-- using a span instead of label as an example !-->
<span class="form--field__label">Second Name</span>
<span>
<input type="text">
</span>
</div>
set input id="firstname" because you want focus on label click. This is builtin feature in html.
<input type="text" id="firstname" name="firstname">
More details here https://www.w3schools.com/tags/tag_label.asp
for multiple input you can use it like this
<form action="/action_page.php">
<label for="male">Male</label>
<input type="radio" name="gender" id="male" value="male"><br>
<label for="female">Female</label>
<input type="radio" name="gender" id="female" value="female"><br>
<label for="other">Other</label>
<input type="radio" name="gender" id="other" value="other"><br><br>
<input type="submit" value="Submit">
</form>
If you still persist you can use it like this
$('.form--field label').click(function() {
//It will look next sibling which is span and then find input in it and then focus it
//so it doesn't focus on other children elements
$(this).next('span').find('input').focus();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="form--field form--field__firstname">
<label class="form--field__label">First Name</label>
<span>
<input type="text" name="firstname">
</span>
<br>
<label class="form--field__label">Last Name</label>
<span>
<input type="text" name="lastname">
</span>
</div>
I know that this might seem like a duplicate, but i can't seem to figure this out. I am wanting to submit a form in HTML to a Popup window. when i hit the submit button, it returns a blank page. I want the pop up to display all of the input that one filled out one the form. I want to do it in JavaScript. This is my code here. I want it to output all of the information entered in the form, from the Personal Information fieldset and the personal choices fieldset. I want it to display as an unordered list.
Heres the Javascript that i have so far:
<head>
<title>My Form</title>
<script type="text/javascript">
function display() {
dispWin = window.open('','NewWin',
'toolbar=no,status=no,width=300,height=200')
message = "<ul><li>First Name:" +
document.mdForm.first_name.value;
message += "<li>Last Name:" +
document.mdForm.the_lastname.value;
message += "<li>Address:" +
document.mdForm.the_address.value;
message += "</ul>";
dispWin.document.write(message);
}
</script>
Heres the HTML:
<body>
<h1>My Form</h1>
<form name="mdForm" method="post" action="">
<fieldset>
<legend>Personal Information</legend>
<p><label class="question" for="first_name">What is your First name?

Have you prevented the default submit functionality?
Try:
function display(e) {
//To stop the submit
e.preventDefault();
...
Do your Stuff
...
//Continue the submit
FORM.submit();
}
I'm trying to make a simple drop down menu which will have two elements: "male" and "female". I'm using a button to have these elements become visible. The problem is that they become visible but only for a fraction of a second and go back to being hidden.
Here's my code:
<html>
<head>
<title>
Validation Form
</title>
</head>
<body>
<h1>
Validation Form
</h1>
<form id="contactForm" action="" >
<fieldset>
<legend>Validation</legend>
<p>
<label for="firstname">First Name</label>
<input id="firstname" name="firstname" type="text"/>
</p>
<p>
<label for="lastname">Last Name</label>
<input id="lastname" name="lastname" type="text" />
</p>
<p>
<label for="gender">Gender</label>
<input id="gender" name="gender" type="text" />
</p>
<div class="dropdown">
<button id="btn_drop" onclick="myFunction()" class="dropbtn">Dropdown</button>
<div id="myDropdown" style="display: none">
<p id="drop_male">Male</p>
<p id="drop_female">Female</p>
</div>
</div>
<p>
<label for="website">Website</label>
<input id="website" name="website" type="text" />
</p>
<p>
<input type="button" id="submit" name="submit" value="Submit" />
<input type="reset" value="clear" />
</p>
</fieldset>
</form>
<script>
var dropBtn = document.getElementById("btn_drop");
dropBtn.onclick = function () {
// show all elements on clicking submit!
var drop = document.getElementById("myDropdown");
drop.style.display = 'block';
}
</script>
</body>
</html>
Look at you browser console. I assume you have an error because you didn't declare myFunction.
Please read this URL: http://www.w3schools.com/jsref/event_onclick.asp and use one of described approaches.
you can make this without javascript live fiddle with css
<p>
<label for="gender">Gender</label>
<select id="gender" name="gender" type='select' >
<option value="">Select Gender</option>
<option value="male">Male</option>
<option value="female">Female</option>
</select>

I'm trying to do a homework assignment and having some issues. I'm supposed to validate a form with Javascript. Right now I'm trying to make sure that a user has checked at least one checkbox (out of four options) in order for the form to submit. (I've gotten other segments of validation to work, so the issue seems to be local to this part of code.)
This is what the html for the checkbox form looks like:
<fieldset>
<input type="checkbox" name="boxes" id="member" value="member" />
<label for="member">I'm a member.</label>
<p><input type="checkbox" name="boxes" id="newsletter" value="newsletter" />
<label for="newsletter">Please send me your monthly newsletter.</label></p>
<p><input type="checkbox" name="boxes" id="preshow" value="preshow" />
<label for="preshow">I'm interested in hearing about pre-show events.</label></p>
<p><input type="checkbox" name="boxes" id ="none" value="none" />
<label for="none">None of the above.</label></p>
And this is what I've written to try to validate it using Javascript:
function validateForm() {
var checkBoxes = document.getElementsByName("boxes");
for (var i=0; i < checkBoxes.length; i++) {
if (checkBoxes[i].checked === true) {
return true;
break;
} else {
alert("At least one checkbox must be selected.");
return false;
}
}
}
This isn't working; the form submits whether boxes have been checked or not.
I would really love to get some help here because I don't have any idea what I'm doing wrong. Like I said, the problem seems to exist somewhere in this specific code, because other validation in separate blocks of code does work.
