How to allow only one radio button to be checked? - html

{% for each in AnswerQuery %}
<form action={{address}}>
<span>{{each.answer}}</span><input type='radio'>
<span>Votes:{{each.answercount}}</span>
<br>
</form>
{% endfor %}
This is a part my django template, what it supposed to do is to print out several radio buttons, corresponding to the answers assigned to the buttons. But I don't know why I can check multiple radio buttons, which messed me up. It is supposed to only let me check on one radio button and I had that somehow but I lost it. Any help? Thank you.

Simply give them the same name:
<input type="radio" name="radAnswer" />

They need to all have the same name.

All radio buttons have to have the same name:
<input type='radio' name='foo'>
Only 1 radio button of each group of buttons with the same name can be checked.

Give them the same name, and it will work. By definition Radio buttons will only have one choice, while check boxes can have many.
<input type="radio" name="Radio1" />

Add "name" attribute and keep the name same for all the radio buttons in a form.
i.e.,
<input type="radio" name="test" value="value1"> Value 1
<input type="radio" name="test" value="value2"> Value 2
<input type="radio" name="test" value="value3"> Value 3
Hope that would help.

Just give them the same name throughout the form you are using.
<form><input type="radio" name="selection">
<input type="radio" name="selection">
..
..
</form>

All the radio buttons options must have the same name for you to be able to select one option at a time.

Only one Step you need to follow!
Make Sure you need to add the attribute name in the opening tag with the same values of that attribute name!
Example :
<input name="18+" value="yes" id="18" type="radio">Yes
<input name="18+" value="No" id="bel" type="radio">No

Can I use more than one name attribute in HTML tag?

I am doing a django project.
But I wanted to have radio buttons grouped as well as name of the buttons to work with django.
Is it okay to use two name attributes in one HTML tag?
Will I be facing any errors if I do so?
Below is my code I am stuck in.
<input type="radio" name="group1" name="removePunc"> Remove Punctuations
<br>
Input name attributes must be unique to send data using traditional forms. If you find yourself needing more attributes, use the data- attributes. Pls share some code to undertand what you are trying to achieve.
If you want to label the group of radio buttons add class="group1" to all of the radio buttons instead of name="group1".
<label for="removePunc">Remove Punctuations</label>
<input type="radio" class="group1" name="removePunc">
<label for="button2">Button 2</label>
<input type="radio" class="group1" name="button2">
<label for="button3">Button 3</label>
<input type="radio" class="group1" name="button3">

radio inputs not working correctly in angular 7

I got radio inputs, rendered using the structural directive ngFor.
<form>
<label *ngFor="let user of staffMembers" class="stuff" for="user.username">
{{user.username}}
<input type="radio" [name]="user.username" [value]="user.username">
</label>
</form>
I got the inputs correctly but i can check multiple fields like checkbox. It's not the default behavior for radio inputs.
Because you are creating a new radio group with each line, not a new radio option. The input [name] is the name of the radio group, NOT the option.
<form>
<label *ngFor="let user of staffMembers" class="stuff" for="staffMembers1">
{{user.username}}
<input type="radio" id="staffMembers1" name="staffMembers" [value]="user.username">
</label>
</form>
The name shouldn't be unique to get the normal behavior, otherwise, it's just radio with only one possibility.
<input type="radio" name="user" [value]="user.username">
You need to give all radio inputs the same name:
https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/radio
Right now it seems each radio input gets a different one since user.username is always different.

Remove Default Checked Option on Radio Button when Another Option is Selected

If i'm using radio buttons in HTML and would like a default option to show as selected, I've used the 'checked' attribute to achieves this. How do I make it so when I check on another option on the radio buttons this default option is removed. In the code below, when you check another option, the original option remains and you can't uncheck anything?
In the option below the fish option is the one with the 'checked' attribute added.

HTML
<input type="radio" id="dog"name="dog"value="dog"><label for="dog">Dog</label>
<input type="radio" id="cat" name="cat" value="cat"><label for="cat">Cat</label>
<input type="radio" id="fish" name="fish" value="fish" checked><label for="fish">Fish</label>
<input type="submit">
Your form radio elements need to have a shared name attribute as they
are the options for one choice. change name to "foo" or "animal" and
it will work.
<div style="margin-bottom:15px;">All radio inputs require a shared name attribute, I declared it "choice"</div>
<form style="text-align:center">
<input type="radio" id="dog"name="choice"value="dog"><label for="dog">Dog</label>
<input type="radio" id="cat" name="choice" value="cat" ><label for="cat" >Cat</label>
<input type="radio" id="fish" name="choice" value="fish" checked="checked" ><label for="fish" >Fish</label>
<input type="submit">
</form>

Input type = radio, can select multiple answers?

Good day, before we start, forgive the noobishness of the question. Just picked up HTML today.
I'm experimenting with the following code:
<form>
<input type="radio" id="radeng" checked />Male
<br/>
<input type="radio" id="radnor" />Female
</form>
Now, the way I understood it, I should be able to pick either "Male" or "Female" from the first selection.
Problem is, I can select both "Male" AND "Female".
Which is a little weird, and kinda' goes against what I'm trying to achieve.
Can anyone spot my error?
17 Forms / 17.2.1 Control types
Radio buttons are like checkboxes except that when several share the same control name, they are mutually exclusive: when one is switched "on", all others with the same name are switched "off".
Therefore if you want the radio elements to be mutually exclusive, you need to give them all the same name attribute. In this case, I gave them both a value of gender.
For usability, I'd also suggest wrapping the text nodes with label elements with for attributes that match the radio element ids. In doing so, you can toggle the radios by clicking the text (label).
<form>
<label for="radeng">Male</label>
<input type="radio" name="gender" id="radeng" checked />
<label for="radnor">Female</label>
<input type="radio" name="gender" id="radnor" />
</form>
You need to provide a name attribute with the same value and it will select only one. Also, you should use <label> tag for specifying the names of your checkboxes.
Lets have some clean markup :
<ul>
<li>
<label for="radeng">Male</label>
<input type="radio" id="radeng" name="gender" checked />
</li>
<li>
<label for="radnor">Female</label>
<input type="radio" id="radnor" name="gender" />
</li>
</ul>
Demo
So by specifying same values for name attribute groups your radio buttons.
Give same name for the both radio button like below:
<form>
<input type="radio" name="gender" id="radeng" checked />Male
<br/>
<input type="radio" name="gender" id="radnor" />Female
</form>

How do I make radio buttons outside of forms?

I'm trying to program a dynamic form, so I can't use the normal form tags and stuff. I use normal buttons, JQuery, and AJAX calls to simulate a traditional form. However, I can't figure out how to do radio buttons. Any help?
EDIT: Yeah, I suppose I should have been more specific. I tried doing
<input type="radio" />
and stuff, but:
it lets me select more than one button at a time (which kind of defeats the point of radio buttons)
it won't let me deselect a button after it's pressed!
EDIT 2: The reason I'm not using form tags is that I need multiple submit buttons as well, and the only solution I found to that dilemma was to not use form tags.
Why can't you use the form tag? There is nothing stopping you from doing so. But if you don't want to use the form tag, why not:
<input type='radio' name='test' value='1' checked>
<input type='radio' name='test' value='2'>
<input type='radio' name='test' value='3'>
<input type='radio' name='test' value='4'>
Works fine for me. Demo
Edit:
1: You need to specify a name for the radio group, otherwise each input is considered its own group. Hence why you can select more than one button at a time when using <input type="radio" />. Look at my code above. The radio group is 'test'.
2: Radio buttons are suppose to have a default value. When you create a radio group you should be specifying a default value with the checked attribute. A consequence of this is that you can't deselect a radio button. You can either choose a different value or stick with the default. If you want to be able to deselect, then consider using checkboxes instead. I've updated the example code to reflect this.
If you are able to select more than one radio button, its sounds like your name attributes are not matching. What you want to end up with is something like the following:
<input type="radio" name="group-1" value="something-unique">
<input type="radio" name="group-1" value="something-else-unique">
<input type="radio" name="group-1" value="another-unique-something">
<input type="radio" name="group-2" value="something-unique">
<input type="radio" name="group-2" value="something-else-unique">
<input type="radio" name="group-2" value="another-unique-something">
Note that the name attribute is the same for the group of options, which means that the selections will replace each other.
Also, I haven't had any issues not wrapping radios in form tags, when using them purely with javascript, however if you want to do any html post stuff, I would expect that they are required.
You can try this:
HTML
<div>
<ul>
<li><input type="radio" name="radio" value="value1" checked>Radio Button1</input></li>
<li><input type="radio" name="radio" value="value1">Radio Button2</input></li>
<li><input type="radio" name="radio" value="value1">Radio Button3</input></li>
</ul>
</div>
DEMO
There should not be an input element without a form element. You are not going to get the HTML to respond the way you want it to if you do not use it correctly. Multiple submit buttons would indicate the need for multiple forms.
If, for whatever reason, that does not work, perhaps you should reconsider the format through which you are asking the user to submit information.
