Retrieving an Existing DOM Element
If you know its ID: element = zjrJS.Doc.eid( "uniqueID" )
If you know its Tag: array = zjrJS.Doc.etn( "tagName" )
If you know its Tag and Sort Index: element = zjrJS.Doc.etn( "tagName" )[ index ]

Creating New DOM Elements
Text: text = zjrJS.Doc.cT( "Hello, World!" )
Non-text: element = zjrJS.Doc.cE( "tagName" )

Adding one DOM Element to another

For instance: adding text to a hyperlink, adding that hyperlink to a paragraph, adding that paragraph to a div, and adding that div to the body.
