//service.useService({webservice location},{webservice class name})
service.useService("http://192.168.2.148:8080/SCRM4U_SERVICE/servlet/aws_system_login_select?wsdl","WS_SYSTEM_LOGIN_SELECT");
//service.Service.callService({webmethod},{input parameters needed})
service.WS_SYSTEM_LOGIN_SELECT.callService(showResult, "Execute", userid, password);
}
function showResult(result)...{
alert(result.value.W_V_USER_MEI);
}
</script>

<br/>
<input type="button" value="callWebservice" onClick="doService(document.getElementById('userid').value,document.getElementById('password').value)"/>

</html>
注意：如果服务返回值类型是String,直接用result.value即可取到值。
