javascript getElementById() method syntax

Function:Returns a reference to the first object with the specified ID.

Syntax:document.getElementById(id)

Description:HTML DOM defines multiple methods for finding elements, except getElementById (), there are also getElementsByName() and getElementsByTagName().However, if you need to find a specific element in the document, the most efficient method is getElementById().When manipulating a specific element of the document, it is best to give the element an id attribute, giving it a unique name (in the document), and then you can use that ID to find the desired element.
