Radio button is not working properly

问题

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.

回答1:

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" />

<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

回答3:

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.

回答4:

Name attribute needs to be the same. Name groups radio buttons together to make them one unit.

回答5:

Name them the same way, and in your php or receiving code it will be something like

$_POST['name'] = 'value of selected radio button'

回答6:

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

回答7:

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

回答8:

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"
