app.component.html
<form #f="ngForm">
<input type="checkbox" name="isTCAccepted" [ngModel]="user" required
#tc="ngModel">Name1
<input type="checkbox" name="isTCAccepted" [ngModel]="user" required
#tc="ngModel">Name2
<input type="checkbox" name="isTCAccepted" [ngModel]="user" required
#tc="ngModel">Name3
<div *ngIf="tc.invalid && f.submitted">
Please check atleast one
</div>
<button>Submit</button>
</form>
As I see, Everything is fine with the code except that name for the input tags should be different, you can have a look into below code,
`
<form #f="ngForm">
<input type="checkbox" name="isTCAccepted1" [ngModel]="user" required
#tc1="ngModel">Name1
<input type="checkbox" name="isTCAccepted2" [ngModel]="user" required
#tc2="ngModel">Name2
<input type="checkbox" name="isTCAccepted3" [ngModel]="user" required
#tc3="ngModel">Name3
<div *ngIf="(tc1.invalid && tc2.invalid && tc3.invalid) && f.submitted">
Please check atleast one
</div>
<button>Submit</button>
</form>

Thank you.
I hope you are good!
I built this piece of code, which results in the following design of a checklist, in which I am able to select multiple items from a list -
<!DOCTYPE html>
<html>
<body>
<h1>Show Checkboxes</h1>
<form action="/action_page.php">
<input type="checkbox" id="item1" name="item1" value="Tshirt">
<label for="item1"> Tshirt</label><br>
<input type="checkbox" id="item2" name="item2" value="Jeans">
<label for="item2"> Jeans</label><br>
<input type="checkbox" id="item3" name="item3" value="Shirt">
<label for="item3"> Shirt</label><br>
<input type="checkbox" id="item4" name="item4" value="Trousers">
<label for="item4"> Trousers</label><br><br>
<input type="submit" value="Submit">
</form>
</body>
</html>
The checklist I get :
And when I choose some items and click submit [for this time I chose Jeans & Trousers], I get my response in this format : item2=Jeans&item4=Trousers. Unfortunately, I cannot further work with this kind of response format...
The format I need should be more like : Jeans , Trousers. No item-ids, and no = signs - just their display names... Is it possible to get a response like that?
Any help would be appreciated! Thanks a lot! 🙂
Edit : Here's the code I took inspiration from - https://www.w3schools.com/tags/tryit.asp?filename=tryhtml5_input_type_checkbox
You can get an array of values in your backed using name format like myarrayName[]. The name attribute doesn't have to be unique. For example:
<form action="" method="post">
<input type="checkbox" id="item1" name="item[]" value="Tshirt">
<label for="item1"> Tshirt</label><br>
<input type="checkbox" id="item2" name="item[]" value="Jeans">
<label for="item2"> Jeans</label><br>
<input type="checkbox" id="item3" name="item[]" value="Shirt">
<label for="item3"> Shirt</label><br>
<input type="checkbox" id="item4" name="item[]" value="Trousers">
<label for="item4"> Trousers</label><br><br>
<input type="submit" value="Submit">
</form>
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>

<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">

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>
My form is currently set up to gather all the input data to my autoresponder...however, I made the form with only one option - pay now. Users would like options, so Im thinking of giving them 2 choices, the old "pay now" COD method, and option#2 paypal. I think radio buttons are the best way for doing this. However I cant get them to work separately...when I choose option 2, option 1 remains selected. So I added the radio buttons myself after the ordernow button.
<p>mail: *</p>

<input type="text" class="wf-input wf-req wf-valid__email" name="mail" class="mj" ></input>

<p>name: *</p>

<input type="text" class="wf-input wf-req wf-valid__required" name="name" class="mj" ></input>

<div class="selectpaymentradios">
<label class="radio" >select payment</label>
<input class="radio" type="radio" name="cash" value="cash" checked /> <span>Ca$h</span>
<input class="radio" type="radio" name="ppal" value="ppal" /> <span>PaypaL</span>
</div>
<input type="hidden" name="webform_id" value="12x45"/>
</p>
</form>
<script type="text/javascript" src="http://xyz.com/view_webform.js?wid=12x45&mg_param1=1"></script>
Im trying to figure out how can I make this work with my autoresponder, I think this form has to be able to tell me what kind of payment did the customer chose...but the autoresponders form creator doesnt have radio buttons at all so Im stuck, I dont know if its possible...
<input class="radio" type="radio" name="cash" value="cash" checked /> <span>Ca$h</span>
<input class="radio" type="radio" name="ppal" value="ppal" /> <span>PaypaL</span>
the problem you hit, is very simple - you have to use the same name for all radio-buttons, where only one item should be selected. like this:
<input class="radio" type="radio" name="payment" value="cash" checked /> <span>Ca$h</span>
<input class="radio" type="radio" name="payment" value="ppal" /> <span>PaypaL</span>
The name attribute should be the same for both radio buttons:
<input class="radio" type="radio" name="method" value="cash" checked="checked" /> <span>Ca$h</span>
<input class="radio" type="radio" name="method" value="ppal" /> <span>PaypaL</span>
Also, if you are closing input tags, you are probably worried about XHTML validation. So instead of just checked you should type checked="checked".
