When you want to consume your own Web services, put them (asmx files) in a sub-directory of your Web server, such as c:\inetpub\wwwroot\Webreference.

init() function assigns a short name to the Web service URL
  • A function to call the Web service with the appropriate parameters
  • A function to display the results
  • The init() function can be shared among Web services. You invoke it upon loading of the page, onload=init().
