如何不提交表单，把文本框值直接赋给Session("text")

function checkid(touxian){   
    //alert(regid);
    var xmlhttp;
    try{
        xmlhttp=new XMLHttpRequest();
        }
    catch(e){
        xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
        }
    xmlhttp.onreadystatechange=function(){
    if (xmlhttp.readyState==4){
        if (xmlhttp.status==200){
            var data = xmlhttp.responseText;
            
            if(data == 1){
            document.getElementById("touxian1").innerHTML = "<img src='images/yesno.gif'  border='0 'align='absmiddle'/>测试";
            }
                //id_result(data);
            //alert(data);
        }
        else{
            //$("span")[0].innerHTML="用户名检测失败,请联系管理员";
            }
        }
    else{
        //alert(1111);
        //$("span")[0].innerHTML="正在进行用户名校验...";
        }
    }//xmlhttp.onreadystatechange=function(){
    xmlhttp.open("post", "zhaopin.asp", true);
    xmlhttp.setRequestHeader('Content-type','application/x-www-form-urlencoded');
    xmlhttp.send("touxian="+escape(touxian));
}
////////

zhaopin.asp页面：
<%
data = 0
touxian = request("touxian")
response.write data
%>
