Radio name Property
Radio Object
Definition and Usage
The name property sets or returns the value of the name attribute of a radio button.
Tip: You define radio button groups with the name property (radio buttons with the same name belong to the same group).
The name attribute is used to identify form data after it has been submitted to the server, or to reference form data using JavaScript on the client side.
Note: Only form elements with a name attribute will have their values passed when submitting a form.
Syntax
Set the name property:
radioObject.name="name"
Return the name property:
radioObject.name
Browser Support
The name property is supported in all major browsers.
Example
Example
Display the value of the name attribute of the "Red" radio button:
<html>
<head>
<script>
function displayResult()
{
var x=document.getElementById("red").name;
alert(x);
}
</script>
</head>
<body>
<form>
