Calling the EchoStringArray Web Service

You can use the echoStringArray method to echo a string array. Place the array elements inside a pair of square brackets, delimited by commas:

iCallID = webServiceCallerBody.echo.callService(
  handleResult, "echoStringArray", ["a","bc","defg"]);
Learn more about Web services in Column 96 (Web services, Part I: Introduction) and Column 97 (Web Services, Part II: Calling Service Methods).

Here is an HTML file that demonstrates calling a Web service. Copy it to your local disk, together with the WebService behavior (webservice.htc):

<HTML>
<BODY ID="webServiceCallerBody" onload="loadService()" 
  STYLE="behavior:url(webservice.htc);background-color:peachpuff;color:brown;font-size:18">
<SCRIPT LANGUAGE="JavaScript">
<!--
function loadService() {
	webServiceCallerBody.onserviceavailable = enableServiceCall;  //Used for the synchronous call.
	webServiceCallerBody.useService(
	  "https://soap.bluestone.com:80/interop/EchoService/EchoService.wsdl","echo");
}
function callAsynch() {
	iCallID = webServiceCallerBody.echo.callService(
	  handleResult, "echoStringArray", ["a","bc","defg"]);
}
function callSynch() {
	var co = webServiceCallerBody.createCallOptions();
	co.funcName = "echoStringArray";
	co.async = false;
	var oResult = webServiceCallerBody.echo.callService(co, ["a","bc","defg"]);
	handleResult(oResult);
}
function enableServiceCall() {
	b2.disabled = false;
}
function handleResult(res) {
  if (!res.error) {
    alert("Successful call. Result is " + res.value);
  }
  else {
    alert("Unsuccessful call. Error is " + res.errorDetail.string);
  }
}
