Syntax: document.getElementsByName(name) Description: This method is similar to the getElementById() method, but it queries the element The name attribute, not the id attribute. In addition, because the name attribute in a document may not be unique (for example, radio buttons in HTML forms usually have the same name attribute), all getElementsByName() methods return an array of elements, not an element.
