js 调用天气预报webservice

天气预报webservice地址：http://webservice.webxml.com.cn/WebServices/WeatherWS.asmx?wsdl

在控制台执行：

var xmlhttp;
xmlhttp=null;
var url="http://webservice.webxml.com.cn/WebServices/WeatherWS.asmx/getRegionProvince";
if (window.XMLHttpRequest)
  {// code for IE7, Firefox, Opera, etc.
    xmlhttp=new XMLHttpRequest();
  }
else if (window.ActiveXObject)
  {// code for IE6, IE5
    xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
if (xmlhttp!=null)
  {
      xmlhttp.onreadystatechange=state_Change;
      xmlhttp.open("GET",url,true);
      xmlhttp.setRequestHeader("Content-Type","text/html; charset=utf-8");
      xmlhttp.setRequestHeader("SOAPAction","http://webservice.webxml.com.cn/WebServices");
      xmlhttp.send(null);
  }
else
  {
  alert("Your browser does not support XMLHTTP.");
  }

function state_Change()
{
if (xmlhttp.readyState==4)
  {// 4 = "loaded"
  if (xmlhttp.status==200)
    {// 200 = "OK"
        console.log(xmlhttp.responseText);
    }
  else
    {
    alert("Problem retrieving XML data:" + xmlhttp.statusText);
    }
  }
}

控制台运行结果：
