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been replaced by the "id" attribute for many elements.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.
