//service.Service.callService({webmethod},{input parameters needed})

function showResult(result)...{

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

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