SOAP调用Web Service

（示例位置：光盘codech07 WebAppClient JsService4.htm）

<html xmlns="http://www.w3.org/1999/xhtml" >
<head>
<title>SOAP对调用WebService</title>
<SCRIPT language="JavaScript">
function GetHelloWorld_SOAP(i)
{
var xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
var soapMessage, soapData, URL;
//设置SOAP信息
soapMessage = "<?xml version="1.0" encoding="utf-8"?>";
soapMessage += "<soap:Envelope xmlns:xsi="http://www.w3.org/2001/
XMLSchema-instance""
+ " xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap=
"http://schemas.xmlsoap.org/soap/envelope/">";
soapMessage += "<soap:Body>";
//设置SOAP数据 ---- begin ------
soapData = "<GetProductPrice xmlns="http://tempuri.org/">";
soapData += " <ProductId>" + i + "</ProductId>";
soapData += "</GetProductPrice>";
//设置SOAP数据 ---- end ------
soapMessage = soapMessage + soapData + "</soap:Body>";
soapMessage = soapMessage + "</soap:Envelope>";
URL = "http://localhost:12074/Service1.asmx"; //WebService地址URL
xmlhttp.Open("POST",URL, false);
xmlhttp.SetRequestHeader ("Content-Type","text/xml; charset=utf-8");
xmlhttp.SetRequestHeader ("SOAPAction","http://tempuri.org/
GetProductPrice");//方法名
xmlhttp.send(soapMessage);
alert(soapMessage)//SOAP数据信息
var x = xmlhttp.responseXML;
alert('调用结果：'+x.childNodes[1].text);
//返回调用状态，状态为200说明调用成功，状态为500则说明出错
alert('状态值：'+xmlhttp.Status);
alert('状态描述：'+xmlhttp.StatusText);
}
</SCRIPT>
</head>
<body>
<INPUT type="button" value="SOAP" onclick="GetHelloWorld_SOAP('001')"
id="Button1" name="Button1">
<INPUT type="button" value="异常测试" onclick="GetHelloWorld_SOAP('')"
id="Button3" name="Button3"><BR><BR>
<div id="div1"></div>
</body>
</html>

具体XMLHTTP的用法和属性可以参考第6.3.8节中的内容。
