How would i add the "value" that are selected from radio boxes in html forms? So when someone selects an option it would add the other "values" onto it and total that it at the bottom of the page. And does anyone know if it could add "names" total "values" onto it as well? thanks
My code looks like this:
<h3><u>Title</u></h3><br>
<form action="">
<input type="radio" name="num" value="0">Text<br>
<input type="radio" name="num" value="2">Text<br>
<input type="radio" name="num" value="80">Text<br>
<input type="radio" name="num" value="110">Text<br>
<input type="radio" name="num" value="85">Text<br>
<input type="radio" name="num" value="120">Text<br>
</form>
You cannot. By definition, a set of radio buttons with the same name attribute contributes at most one value to the data set, the one corresponding to the selected button.
If you want something else, you should handle that server side, or use other types of controls, or redesign the entire approach.
Working example :
(using a Javascript library, jQuery, but could be done in plain JavaScript)
You mainly have to change your inputs to type="checkbox" in the HTML
What code does : when a checkbox's state is modified, all checked checkboxes' value are summed up in the last input field I've added
The checkboxes are targetted by looking for "num" in their name, if you remove that the checkbox won't be taken into account by the script.
$(function() {
$("input[name*='num']").on("change", function() {
var total = 0;
$("input[type='checkbox']:checked").each(function() {
total += Number($(this).val());
});
$("#total").val(total);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<h3>
<u>Title</u>
</h3>
<br>
<form action="">
<input type="checkbox" name="num0" value="0">Add 0<br>
<input type="checkbox" name="num2" value="2">Add 2<br>
<input type="checkbox" name="num80" value="80">Add 80<br>
<input type="checkbox" name="num110" value="110">Add 110<br>
<input type="checkbox" name="num85" value="85">Add 85<br>
<input type="checkbox" name="numwhateveryoulike" value="120">Add 120<br>
Total <input type="text" value="0" id="total">

In my html page, I cant add two radio buttons, I get an error in free-code-camp and that is about to have two radio buttons in label element with attribute of same name value for both of them in input self-closing tag.
I tried the same value for name attribute in input tag within the label element. but I got error.
<label>
<input id="indoor" type="radio" name="indoor-outdoor" > Indoor
</label>
<label>
<input id="outdoor" type="radio" name="indoor-outdoor" > Outdoor
</label>
The following example shows three radio buttons with the same name, within a label, within a form.
This is a valid structure.
const handleSubmission = (form, event) => {
event.preventDefault();
console.log(`Choice: ${form.elements.foo.value}`);
};
<form onSubmit="handleSubmission(this, event)">
<label>
<strong>Choice:</strong>
<input type="radio" name="foo" value="a" /> A
<input type="radio" name="foo" value="b" /> B
<input type="radio" name="foo" value="c" /> C
</label>
<button type="submit">Submit</button>
</form>
We currently use the following syntax for radio buttons:
<input type="radio" id="opt1" name="option" value="opt1" required/>
<label for="opt1">Description of Option One</label>
<input type="radio" id="opt2" name="option" value="opt2" required/>
<label for="opt2">Description of Option Two</label>
The query-processing script receives the string "opt1", which it then needs to convert to the full-text description of the option. In PHP-speak, I get:
$_POST['option'] => "opt1"
I'd like to save that step and have the full text of the description to be submitted as the value:
$_POST['option'] => "Description of Option One"
Can this be done with HTML alone -- without resorting to JavaScript-rewriting hacks and without duplicating the description text in the HTML? Thanks!
Unfortunately not.
If you have control over the form, the best solution is to use the description for the value:
<input type="radio" id="opt1" name="option" value="Description of Option One" required/>
<label for="opt1">Description of Option One</label>
<input type="radio" id="opt2" name="option" value="Description of Option Two" required/>
<label for="opt2">Description of Option Two</label>
If you don't have control over the form, then javascript is your only solution, you could use a function like the below (either inside an onload event for the page or an onsubmit event on the form:
function radioUpdate() {
document.querySelectorAll('radio').forEach(function(input) {
input.value = document.querySelector('label[for="' + input.id + '"]').text();
});
};
No, it can't.
Consider generating the HTML from your server side code in the first place. You could write a PHP function that takes the label/value as a single argument.
first post.. graphics person becoming a coder here. (Coding is more fun, but harder!)
2 radio groups each with 2 buttons. I have got it working where if either #client or #agent is selected from Radio 1, and #companyClient is selected from radio 2, the result is the text fields beneath the radio groups stay Readonly except #companyName. I also have it working where if #agent is selected from Radio 1, and #individualClient is selected from radio 2, the result is the text fields beneath the radio groups become editable to collect input except #companyName which stays Readonly.
What I need though is if #client is selected from Radio 1, and #individualClient is selected from radio 2, the text fields beneath the radio groups (except #companyName) stay Readonly; currently they are editable which I don't want. And I need to copy the text field values from #firstnameContact, #lastnameContact, and titleContact to them (ie to firstnameClient, lastnameClient and titleClient).
Thanks
JS
$(function(){
$("#companyClient, #individualClient").change(function(){
$("#firstnameClient, #lastnameClient, #titleClient, #companyName").val("").attr("readonly",true);
if($("#individualClient").is(":checked")){
$("#firstnameClient, #lastnameClient, #titleClient").removeAttr("readonly");
$("#companyName").attr("readonly");
$("#firstnameClient").focus();
}
else if($("#companyClient").is(":checked")){
$("#companyName").removeAttr("readonly");
$("#companyName").focus();
}
});
});
HTML
<label for="firstnameContact">First Name</label>
<input type="text" name="firstnameContact" id="firstnameContact" />
<label for="lastnameContact">Last Name</label>
<input type="text" name="lastnameContact" id="lastnameContact" />
<label for="titleContact">Title</label></div>
<input type="text" name="titleContact" id="titleContact" />
<!--Radio 1 -->
<label>Your Status</label>
<input type="radio" name="yourStatus" id="client" value="client" checked />
<label for="client">I am the Client</label>
<input type="radio" name="yourStatus" id="agent" value="agent" />
<label for="agent">I am an Agent</label></div>
<!--Radio 2 -->
<label>select one:</label>
<input type="radio" name="clientType" id="companyClient" value="companyClient" />
<label for="companyClient">Company</label>
<input type="radio" name="clientType" id="individualClient" value="individualClient" />
<label for="individualClient">Individual</label>
<label for="companyName">Company Name</label>
<input type="text" name="companyName" id="companyName" readonly />
<label for="firstnameClient">First Name</label></div>
<input type="text" name="firstnameClient" id="firstnameClient" readonly />
<label for="lastnameClient">Last Name</label>
<input type="text" name="lastnameClient" id="lastnameClient" readonly />
<label for="titleClient">Title</label></div>
<input type="text" name="titleClient" id="titleClient" readonly />
Just added a form around all elements and made the change on it, seems to works.
See this fiddle
$(function(){
$("form").change(function(){
$("#firstnameClient, #lastnameClient, #titleClient, #companyName").val("").attr("readonly",true);
if($("#individualClient").is(":checked")){
$("#firstnameClient, #lastnameClient, #titleClient").removeAttr("readonly");
$("#companyName").attr("readonly");
$("#firstnameClient").focus();
}
else if($("#companyClient").is(":checked")){
$("#companyName").removeAttr("readonly");
$("#companyName").focus();
}
});
});
EDIT
Or you can use disabled to make it more clear for users.
See this fiddle
$(function(){
$("form").change(function(){
$("#firstnameClient, #lastnameClient, #titleClient, #companyName").val("").prop("disabled",true);
if($("#individualClient").is(":checked")){
$("#firstnameClient, #lastnameClient, #titleClient").removeProp("disabled");
$("#companyName").prop("disabled",true);
$("#firstnameClient").focus();
}
else if($("#companyClient").is(":checked")){
$("#companyName").removeProp("disabled");
$("#companyName").focus();
}
});
});
Of course, you can add a PHP validation and test of all fields to make it safier and better.
I'm trying to come up with a form comprised of radio buttons group where a user must select one of the options and if he doesn't there's a custom validity message.
So the logic will be:
A user forgets to select an option and the validity message shows up.
He goes back and selects any option to go proceed.
The problem is, the way things are it only goes ahead if the selected option is the one with the onclick event as shown below. If it isn't then the message will keep showing up.
I have tried to juggle around with the required, oninvalid and onclick thingies but to no avail. Any ideas?
Thanks!
<form>
<input type="radio" name="test" value="0" required oninvalid="this.setCustomValidity('Click me')" onclick="setCustomValidity('')">Zero<br>
<input type="radio" name="test" value="1" class="wrapper">One<br>
<input type="radio" name="test" value="2" class="wrapper">Two<br>
<input type="submit">
</form>
<form>
<input type="radio" id="test" name="test" value="0" oninvalid="this.setCustomValidity('Click me')" onclick="clearValidity();" required >Zero<br>
<input type="radio" name="test" value="1" onclick="clearValidity()" class="wrapper">One<br>
<input type="radio" name="test" value="2" onclick="clearValidity()" class="wrapper">Two<br>
<input type="submit">
</form>
<script>
function clearValidity()
{
document.getElementById('test').setCustomValidity('');
}
</script>
This can be written as a function to make it work on any type of <input>:
document.querySelectorAll('form *[data-custom-validity]').forEach(el => {
const firstInput = el.querySelector('input:first-of-type')
// set custom validity if first input is invalid
firstInput.addEventListener('invalid', () => firstInput.setCustomValidity(el.dataset.customValidity))
// listen on all inputs for a change
el.querySelectorAll('input').forEach(input =>
input.addEventListener('change', () => firstInput.setCustomValidity('')))
})
<form>
<div data-custom-validity="Click me.">
<input type="radio">
<input type="radio">
</div>
</form>
This worked for me, I'm leaving it here in case it helps anyone.
<div class="genero">
<input type="radio" name="radiogroup" oninvalid="setCustomValidity('Mensaje')" onchange="try{setCustomValidity('')}catch(e){}" value="M">Masculino
<input type="radio" name="radiogroup" oninvalid="setCustomValidity('Mensaje')" onchange="try{setCustomValidity('')}catch(e){}" value="F">Femenino
</div>
How can I prevent a user from selecting multiple checkboxes in HTML?
you should change it to radio button instead of check box!
<input type="radio" name="group1" id="item1" value="Milk">
<label for="item1">Milk</label>
<br/>
<input type="radio" name="group1" id="item2" value="Butter" checked>
<label for="item2">Butter</label>
<br/>
<input type="radio" name="group1" id="item3" value="Cheese">
<label for="item13">Cheese</label>
I had a use case where I needed use checkboxes--which, unlike radio buttons, allows a user to UNcheck... Here's an example of something I pieced together from another stackoverflow user:
<head>
<meta charset=utf-8 />
<title>and-or checkboxes</title>
<script src="http://code.jquery.com/jquery-1.4.4.js"></script>
</head>
<body>
<label for="checkbox1"><input type="checkbox" id="checkbox1" name="checkbox1" value="and" </label><span id="span_and">checkbox1</span><br>
<label for="checkbox2"> <input type="checkbox" id="checkbox2" name="checkbox2" value="or" </label><span id="span_or">checkbox2</span>
<script>
$(document).ready(function(){
$('#checkbox1').click(function() {
var checkedBox = $(this).attr("checked");
if (checkedBox === true) {
$("#checkbox2").attr('checked', false);
} else {
$("#checkbox2").removeAttr('checked');
}
});
});
$(document).ready(function(){
$('#checkbox2').click(function() {
var checkedBox = $(this).attr("checked");
if (checkedBox === true) {
$("#checkbox1").attr('checked', false);
} else {
$("#checkbox1").removeAttr('checked');
}
});
});
</script>
</body>
With a little work, you can combine the either/or two scripts into a single script. You probably don't need this now but I wanted to post it because it was very useful to me.
If you want that only one checkbox get selected at a time then its better to use radiobutton instead.
If you mean that you don't want multiple checkboxes from a same "logical group" to be checked at one time, you should use radio buttons instead of checkboxes.
<form>
<input type="radio" name="aGroup" value="choice1" /> Choice #1<br />
<input type="radio" name="aGroup" value="choice2" /> Choice #2
</form>
By using this, only 1 option can be checked at one time
Use Radio, and they must have the same name="".
