JS调用web service的通用函数

http://www./showtopic-22580.html

调用：

RequestByPost(method,variable,value,url,_Namespace)

 

method:web service的方法名

variable：web service的方法的变量名数组

value：web service的方法的变量的值的数组

url：请求的地址（asmx文件地址）

_Namespace：web service的命名空间

 

<script language="javascript" type="text/javascript">

// <!CDATA[

//define

var xmlhttp;

var value=new Array();

var variable=new Array();

//Show Response MSG.

function handleStateChange()

{

    var h=document.getElementById("Label1");

默认的命名空间名字应该以“/”结尾
