页面:
<INPUTtype=\"button\"value=\"Button\"onclick=\"getdata
\"><br> <spanid=\"div1\"
=\"list\"></span> <scriptlanguage=javascript>
Interval(getdata,1000);//动态定时

脚本:
<SCRIPTID=\"clientEventHandlersJS\"LANGUAGE=\"javascript\">

docSubmit=
ActiveXObject(\"Microsoft.XMLDOM\"); docSubmit.async=false;
docSubmit.load(\"http://localhost/WebApplication1/Service1.asmx/GetData?maxval=5\");

//如果返回是个

window.alert(s);
td_AD.innerHTML=s;
}
//
Interval(chang,2000);//间隔执行 [Page]</script>
注意:
在fromework1.0和1.1是有区别
, 在1.1
machine.config(C:\\WINNT\\Microsoft.NET\\Framework\\v1.1.4322\\CONFIG),默认webservice去除了post,get思路方法 你可在你
machine.config中加上或者只在webServices项目Web.config<system.web>里加上: <webServices>
<protocols>
<addname=\"HttpPost\"/>
<addname=\"HttpGet\"/>
</protocols>
</webServices>
否则
在ie地址栏输入webServices访问地址串时提示:请求格式无法识别
还有
docSubmit=
ActiveXObject(\"MSXML2.DOMDocument\");//1.0 换成
docSubmit=
ActiveXObject(\"Microsoft.XMLDOM\");//1.1 －－－－－－－－－－－－－－－－－－－－－－－－－－
web服务思路方法:
[WebMethod]
public
GetData(maxval) {
BaseClass.DbManagerSqldbm=
BaseClass.DbManagerSql; strSql=\"select*froms_KeShiwhereKeshidm>\"+maxval; DataSetds=dbm.Query(strSql);
ds.GetXml; }
返回
xml数据: <?xmlversion=\"1.0\"encoding=\"utf-8\"?>
