博客展示了两段JavaScript代码。`ChkCategoryID`函数用于查询是否弹出用户树，会检查分类ID，若为空提示选择分类，还会调用`RemoteRun`函数进行远程检查。`RemoteRun`函数实现远程调用，通过XMLHTTP对象发送SOAP请求并处理响应。

//查询是否需要弹出用户树，当没有分类或非组分类时不需弹出
function ChkCategoryID(CatID)
{

if (CatID == "")
{
alert("请先选择分类！");
return false;
}

var SoapBody = "<CatID>";
SoapBody += CatID;
SoapBody += "</CatID>";

var url = "../Common/JumpWebService.asmx";
var MethodName = "ChkIsGroupByCatID";
var result = RemoteRun(url, MethodName, SoapBody);

if( result == "true")
{
  //可以显示树
}
else
{
  alert("公开分类的对象为全体，个人分类的对象为作者本身，不需指定对象！");
  return false;
}
return true;
}

function RemoteRun(page, Method, SoapBody)
{
var url = page + "?methodname=" + Method;
var xmlhttp,dom,node,xmlDOC;

var SoapHead = "<?xml version='1.0' encoding='utf-8'?>" +
     "<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/'><soap:Body><" + Method + " xmlns='http://localhost'>";
var SoapTail = "</" + Method + "></soap:Body></soap:Envelope>";

var SoapRequest = SoapHead + SoapBody + SoapTail;

xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
xmlhttp.Open("POST",url,false);
xmlhttp.setRequestHeader("Content-Type", "text/xml;charset=utf-8");
xmlhttp.setRequestHeader("SOAPAction", "http://localhost/"+Method);
xmlhttp.setRequestHeader("Content-Length",SoapRequest.length);
xmlhttp.Send(SoapRequest);

if( xmlhttp.Status == 200 )
{
  var result = xmlhttp.responseXML.getElementsByTagName(Method + "Result");
  if(result)
  {
   return result(0).text;
  }
}
