ajax传值写法

var xmlDoc = originalRequest.responseText.trim();
或者 originalRequest.responsexml;

如下是其一的示例

java: //获得在线用户数
public void getRuOnlineCount() throws Exception{
this.ruonline = ce.GetRuOnlineCount(uIdName);
Element element = new Element("ruonline");
Document document = new Document(element);

if(0 != this.ruonline ){

Element ruonlinecount = new Element("ruonline");
element.addContent(ruonlinecount);

}
ResponseUtil.println(String.valueOf(this.ruonline));
}


js:   //获取在线用户数
  function getRuOnlineCount()
  {
  var url='getRuOnlineCount.action';
  var pars = "uIdName=" + $("#vpnId").val();
  $.ajax({
type : 'post',
url : url,
data : pars,
contentType: "application/x-www-form-urlencoded; charset=UTF-8",
async: true,
complete:ruonline
});
 
  }
  function ruonline(originalRequest)
  {
 
  var xmlDoc = originalRequest.responseText.trim();
 
  var onlineuserLengthTd = document.getElementById("onlineuserLengthTd");  
  onlineuserLengthTd.innerHTML= xmlDoc;
 
  }
