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>

I work on a large Backbone application at work. The interface is essentially a big form. We use the name attribute to map our inputs to our model properties so we can autosave each field on change or enter, letting Backbone do its thing. I just spent two days trying to figure out why one particular section causes the page to reload with a weird URL. The answer is obvious now, but after building a big app over 9 months, you tend to overlook the small things.
Throughout the application we use <input> all over the place without a wrapping <form>. In one case, however, we have a repeating element in the form of a Handlebars template that contains radio buttons with the same name:
<div id="1">
<input type="radio" name="choose" value="yes"> Yes
<input type="radio" name="choose" value="no"> No
<input type="text">
</div>
<div id="2">
<input type="radio" name="choose" value="yes"> Yes
<input type="radio" name="choose" value="no"> No
<input type="text">
</div>
<div id="3">
<input type="radio" name="choose" value="yes"> Yes
<input type="radio" name="choose" value="no"> No
<input type="text">
</div>
The problem with this is that they get grouped together because of they all have the same name attribute. So, instead of getting 3 values (one for each group), we were getting 1 value (for one big group).
Since we know that radio button groups are "scoped" to the containing <form>, we just wrapped it:
<div id="1">
<form>
<input type="radio" name="choose" value="yes"> Yes
<input type="radio" name="choose" value="no"> No
<input type="text">
</form>
</div>
<div id="2">
<form>
<input type="radio" name="choose" value="yes"> Yes
<input type="radio" name="choose" value="no"> No
<input type="text">
</form>
</div>
<div id="3">
<form>
<input type="radio" name="choose" value="yes"> Yes
<input type="radio" name="choose" value="no"> No
<input type="text">
</form>
</div>
This works just fine for the radio buttons, but now that we have a form, hitting enter on the text <input> actually submits the form, instead of autosaving (technically, in addition to autosaving). At the time, this never even occurred to me, since we somehow managed to avoid this everywhere else in the application.
I can think of a few different solutions to this problem: setting a submit handler on the form, setting a submit handler on the text input, leaving the text input outside the form. But these seem like hacks to deal with what I would say is broken behavior. If input elements work outside of forms, then grouping input elements should work outside of forms. And since we're already using the name attribute (which works for everything else), unique names isn't really an option.
So is there a best practice for situations like this? Is there an element other than <form> that will properly scope radio buttons? Am I just going to have to live with <form onsubmit="return false;">?
P.S. We support IE 8+
UPDATE
This is what I ended up with:
<div id="1">
<form onsubmit="return false;">
<input type="radio" name="choose" value="yes"> Yes
<input type="radio" name="choose" value="no"> No
</form>
<input type="text">
</div>
Best thing to do would be to change the names of each group to be unique.
Second best would be to group them by form like you have done, and add the return false.
Third best would be to block form submission using jquery 'preventdefault' (which could work for all forms given a particular id).
Last (and the most ridiculous option) would be to send each group of buttons to it's own small html file and use iframes to display them on the same page.
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).
I have a form with these fields and for some reason attendance only comes through as 'Yes' despite you selecting the 'No' radio button.
Any ideas why and if there is anything wrong with what I have done?
<label>
<input type="radio" name="attendance" value="No" id="attendance" />
Yes</label>
<label>
<input type="radio" name="attendance" value="Yes" id="attendance" />
No</label>
<label>
<input type="radio" name="attendance" value="No" id="attendance" />
No</label>
<label>
<input type="radio" name="attendance" value="Yes" id="attendance" />
Yes</label>
Your label is No while the value of the radio button is Yes :)
Also as others have noted: you cannot have two elements with the same id. You could just use a class for this.
Use this instead:
<label>
<input type="radio" name="attendance" value="Yes" id="attendance-yes" />
Yes</label>
<label>
<input type="radio" name="attendance" value="No" id="attendance-no" />
No</label>
you had your labels and your values reversed...
You can't have the same id for two elements. Remove id or assign different ids.
An id should be unique, so you should give the elements different identities.
I'm not sure if that is the cause of the problem, but that is the only error in the code that you have shown. If that doesn't help, the problem is in the part of the code that you haven't shown.
As others have mentioned, you have swapped the values and labels betwwen the radio buttons, but that seems to be too obvious...
I see two mistakes in the code given:
the label tag should only surround the effective label (not the input tag)
the two items have the same id, i think that's why you always get the same result
You might differenciate the ID as it should be unique. Also you could use the attribute for for the label markup.
Like this :
<label for="attendanceyes">
<input type="radio" name="attendance" value="Yes" id="attendanceyes" />
Yes
</label>
<label for="attendanceno">
<input type="radio" name="attendance" value="No" id="attendanceno" />
No
</label>
I'm using the jQuery Validate to validate my form. It's a form with text and radio types and also with a selector.
The validation is working great, but when validating radio buttons the error div shows in between the buttons and not at the end of the row of them.
How can I place this div in a different position without moving it for the rest of the form's fields?
YOu can use the code from this exemple: http://jquery.bassistance.de/validate/demo/radio-checkbox-select-demo.html
<fieldset>
<legend>Gender</legend>
<label for="gender_male">
<input type="radio" id="gender_male" value="m" name="gender" validate="required:true" />
Male
</label>
<label for="gender_female">
<input type="radio" id="gender_female" value="f" name="gender"/>
Female
</label>
<label for="gender" class="error">Please select your gender</label>
</fieldset>
and change the
<label for="gender" class="error">position
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).
