You need to have three JavaScript functions for each Web service you consume:

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. It is invoked upon loading of the page, onload=init(). We call the behavior's useService() method to assign short identifiers to the Web service's rather-long URL. We call the Add Web service by simpleCalcWebService and the isPrime Web service by isPrimeNumberWebService:

    function init() {
  myWebService.useService("
    http://www.dev1.eraserver.net/D2S/WebServiceSample/isPrime.asmx?WSDL",
    "isPrimeNumberWebService");
  myWebService.useService("http://63.210.240.215/d2s/20011205/add.asmx?WSDL",  
    "simpleCalcWebService");
}
    These Web service examples work properly in Internet Explorer 5.5 or later browsers. If you are using Internet Explorer 5.5+ and receiving errors with the examples, you need to enable the access data sources across domains option. See Column 105 for details.
