Taken from Gesing and Schneider, p. 152.
This uses an alert box to display two properties of the navigator object. Please note:

  • The "onLoad" condition is set in the HTML BODY tag to invoke a short script named "navShow()".
  • The "navShow()" script just writes two properties of The browser object.
  • The browser name is in the "appName" property.
  • The browser version number and platform is in the "appVersion" property.
  • By itself this is not very useful except to show that the information is retrievable. It could be used to control execution of other script code. Heinle, p.96 shows an example of this.
