Definition and Usage
The getElementsByName() method returns a collection of all elements in the document with the specified name (the value of the name attribute), as a NodeList object.
The NodeList object represents a collection of nodes. The nodes can be accessed by index numbers. The index starts at 0.
Tip: You can use the length property of the NodeList object to determine the number of elements with the specified name, then you can loop through all elements and extract the info you want.
Note: In HTML5, the "name" attribute is deprecated and has been replaced by the "id" attribute for many elements. Use the document.getElementById() method where it is appropriate. Also look at the getElementsByClassName() and getElementsByTagName() methods.
