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>

In the form below, when I click the first radio button then I click the second radio button, both remain checked. The behaviour I want is for when I click on radio button, the other radio button gets unchecked automatically. I am using React.js with styled components.
<form>
<input type="radio"/>
<input type="radio"/>
</form>
Give the same name to all the radio buttons (but different values).
<form>
<input type="radio" name="radio" value="1"/> 1st
<input type="radio" name="radio" value="2"/> 2nd
</form>
You have give each radio button a name property with the same value like "group1". Like so:
<form>
<input type="radio" name="group1"/>
<input type="radio" name="group1"/>
</form>
I have a HTML form with radio buttons and are able to select multiple but why? I can't help myself.
This is my HTML:
<input type="radio" name="nameA" id="nameA" value="nameA">
<label for="nameA">Choice A</label>
<input type="radio" name="nameB" id="nameB" value="nameB">
<label for="nameB">Choice B</label>
For anyone finding this question: Solution is to give them the same NAME
<input type="radio" name="sameName" id="nameA" value="nameA">
<label for="nameA">Choice A</label>
<input type="radio" name="sameName" id="nameB" value="nameB">
<label for="nameB">Choice B</label>
All radio buttons that share the same name and are controls in the same form are part of a group.
Only one radio button in a group can be checked.
You have two radio buttons with different names. This means that you have two radio groups, each containing one radio button.
You need to put them in the same group (by making them share a name) if you only want one of them to be selected.
(They should still have unique ids (so you can give each one a label) and values (which is how you determine which one was checked when the form is submitted to the server)).
<form>
<fieldset>
<legend>Thing that is being chosen</legend>
<input type="radio" name="name" id="nameA" value="nameA">
<label for="nameA">Choice A</label>
<input type="radio" name="name" id="nameB" value="nameB">
<label for="nameB">Choice B</label>
</fieldset>
</form>
Whenever you are creating radio buttons (with the intention of
ensuring users would be able to select only 1 option), please ensure
to have the value of the name attribute the same
Please update your code like this :
<input type="radio" name="sameName" id="nameA" value="nameA">
<label for="nameA">Choice A</label>
<input type="radio" name="sameName" id="nameB" value="nameB">
<label for="nameB">Choice B</label>
<input type="radio" name="allotdeallot" value="Allotment" />Allotment
<input type="radio" name="allotdeallot" value="De-Allotment" />De-Allotment
I have two radio buttons which I want to check or uncheck on label click.
Use the <label> tag and add the id attribute to the radio button:
<input type="radio" name="allotdeallot" id="allotment" value="Allotment" /><label for="allotment">Allotment</label>
<input type="radio" name="allotdeallot" id="deallotment" value="De-Allotment" /><label for="deallotment">De-Allotment</label>
More information
As per HTML standards, every form element must have label attach to it. You wish to hide the text of label, you can hide the text of the lable, by using position:absolute to the label. So here is your answer,
<input id="allotment" type="radio" name="allotdeallot" value="Allotment" /><label for="allotment">Allotment</label>
<input id="de-allotment" type="radio" name="allotdeallot" value="De-Allotment" /><label for="de-allotment">De-Allotment</label>
The id of the input field must be same with for attribute of the label.
In my web page I have placed some radio buttons. But these buttons are not working properly. I can check multiple buttons.
code:
<label for="abc" style="margin-top:-20px;margin-left:40px">xyz</label>
<input type="radio" id="abc" name="abc" >
<label for="bcd" style="margin-top:-20px;margin-left:40px">abc</label>
<input type="radio" id="bcd" name="bcd" >
<label for="efg" style="margin-top:-20px;margin-left:40px">ccc</label>
<input type="radio" id="efg" name="efg" >
fiddle
I want to check only one button. Please any one help me.
Because you've different value for name attribute, they should have a common name value, just like you group items.. for example
<input type="radio" name="group1" />
<input type="radio" name="group1" />
<input type="radio" name="group1" />
<!-- You can select any one from each group -->
<input type="radio" name="group2" />
<input type="radio" name="group2" />
<input type="radio" name="group2" />
Demo
<label for="abc" style="margin-top:-20px;margin-left:40px">xyz</label>
<input type="radio" id="abc" name="abc" >
<label for="bcd" style="margin-top:-20px;margin-left:40px">abc</label>
<input type="radio" id="bcd" name="abc" >
<label for="efg" style="margin-top:-20px;margin-left:40px">ccc</label>
<input type="radio" id="efg" name="abc" >
All inputs must have the same name="" attribute value
Radio buttons which are grouped together must have the same case-sensitive name property.
<label for="input1">First Input</label>
<input type="radio" id="input1" name="inputGroup" >
<label for="input2">Second Input</label>
<input type="radio" id="input2" name="inputGroup" >
<label for="input3">Third Input</label>
<input type="radio" id="input3" name="inputGroup" >
JSFiddle demo.
From the HTML specification:
Radio buttons are like checkboxes except that when several share the same control name, they are mutually exclusive.
Give same name to all radio button from which you want to select one option
<label for="abc" style="margin-top:-20px;margin-left:40px">xyz</label>
<input type="radio" id="abc" name="abc" >
<label for="bcd" style="margin-top:-20px;margin-left:40px">abc</label>
<input type="radio" id="bcd" name="abc" >
<label for="efg" style="margin-top:-20px;margin-left:40px">ccc</label>
<input type="radio" id="efg" name="abc" >
Now it will work properly
Name attribute needs to be the same. Name groups radio buttons together to make them one unit.
Name them the same way, and in your php or receiving code it will be something like
$_POST['name'] = 'value of selected radio button'
The name setting tells which group of radio buttons the field belongs to. When you select one button, all other buttons in the same group are unselected.
If you couldn't define which group the current button belongs to, you could only have one group of radio buttons on each page.
e.g :
<input type="radio" name="fruit1" value="Apple"> Apple <br>
<input type="radio" name="fruit1" value="Apricot" checked> Apricot <br>
<input type="radio" name="fruit1" value="Avocado"> Avocado
<hr>
<input type="radio" name="fruit2" value="Banana"> Banana<br>
<input type="radio" name="fruit2" value="Breadfruit"> Breadfruit<br>
<input type="radio" name="fruit2" value="Bilberry" checked> Bilberry
Give the name the same attribute.
The checked attribute can be used to indicate which value should be selected. Somewhere in your syntax for the value you want checked write checked="checked"
I reached this thread searching the keywords "html radio not working". After reviewing my code, I noticed that I used a javascript method "event.preventDefault();" in this custom function that I've made where the HTML node that triggered this event in that custom function were the "not working" radio parent. So I solved my problem removing the "event.preventDefault();". If someone reached this thread in the future, I hope this help you somehow (even for debbuging purposes).
If I want to have a question with a "Yes/No" radio button. How do I need to mark up the code so that a screen reader reads the question associated with the "yes/no" selection instead of just reading the "Yes" and "No" labels when the radio buttons are selected?
<span>Did you understand this? (choose one) </span>
<label>
<input type="radio" id="yes_no" name="yes_no" value="Yes" />
Yes
</label>
<label>
<input type="radio" id="yes_no" name="yes_no" value="No" />
No
</label>
Thanks
For form elements of this nature I use:
<fieldset>
<legend>Did you understand the question?</legend>
<input type="radio" name="yes_no" id="yes">
<label for="yes">Yes</label>
<input type="radio" name="yes_no" id="no">
<label for="no">No</label>
</fieldset>
Also please take note that all ID values on a page should be unique. If you have an element that needs to share a descriptor then add it as a class.
I also use Fieldsets to add a distinct boundary to the radio selection.
And be sure to specify the for="id_value" attribute of the label. This will associate the label with the desired radio button.
<fieldset>
<legend><span>Did you understand this? (choose one) </span></legend>
<label>
<input type="radio" id="yes_no" name="yes_no" value="Yes" />
Yes
</label>
<label>
<input type="radio" id="yes_no" name="yes_no" value="No" />
No
</label>
</fieldset>
use the content attribute (if it is available).
