.net 下用javascript调用webservice

这里id是我们在div里设置的id,而FridndbyName是我们刚才为方面而起的命，这里就是MyMath了，而CallbackHandler是使用回调函数的过程名，如果无设置的话，则默认是使用onresult所调用的方法来进行处理，下文会讲到，而param1,,param2等则是说传入的参数了，如：

<SCRIPT language="JavaScript">

// All these variables must be global,

// because they are used in both init() and onresult().

var iCallID = 0;

var intA = 5;

var intB = 6;

function init()

{

// Establish the friendly name "MyMath" for the WebServiceURL

service.useService("/services/math.asmx?WSDL","MyMath");

// The following method doesn't specify a callback handler, so onWSresult() is used

iCallID = service.MyMath.callService("add", intA, intB);

}

function onWSresult()

{

// if there is an error, and the call came from the call() in init()

if((event.result.error)&&(iCallID==event.result.id))

{

// Pull the error information from the event.result.errorDetail properties
