JavaScript Location

• JavaScript function definitions may be given in a document's HEAD or BODY, using the SCRIPT tag

  <SCRIPT language="JavaScript">
  function bar() {
      document.write("Hello World");
  }
  </SCRIPT>
  

• Functions need to be declared before use, so place them in the HEAD
• Hiding code in comments is a kludge
• Event handlers are placed in the HTML tag for the object

  <INPUT TYPE="button" onClick="bar()">
