How to get elements by name in javascript

13 Dec

The getElementsByName() method is used to get the element by name. However be aware of the getElementsByName() method always return an array.

Example:

<!DOCTYPE html>
<html>
<head>
 <script type="text/javascript">
 function getElements(){
 var x=document.getElementsByName("x");
 for(var i=0;i<x.length;i++){
 alert(x[i].value);
 }
 }
 </script>
</head>
<body>
 Cats: <input name="x" type="radio" value="Cats" />
 Dogs: <input name="x" type="radio" value="Dogs" />
<input type="button" onclick="getElements()" 
value="clickToGetByName"/>
</body>
</html>

There are no getElementByName() exists, Its getElementsByName().
