Foil 21 "Hello World" Example (cont'd)

From Overview of JavaScript I -- Basic Web Scripting Language CPS616 Technologies of the Information Age -- Spring Semester 99. by Geoffrey C. Fox (Tom Scavo)

Simple scripts for Foil 21
1 There is only one JavaScript statement: document.writeln("<H1>Hello World!</H1>");
2 The writeln method writes its argument into the current document
3 The script is in the <BODY> since it writes HTML code into the document; other scripts are written in the <HEAD> so they are processed and available in body
  • Actually in advanced applications, when JavaScript is actually defined becomes quite tricky and is an example of how there are intrinsically undefined features in language
4 Scripts may be hidden from old browsers using arcane construct <SCRIPT LANGUAGE="JavaScript" > <!-- A comment to a dinosaur .... Bunch of Exciting JavaScript Statements ..... //script ends here --> </SCRIPT>
