运行上面的html文件 可以显示 1 2 3 4 5 
可一单击超链接时，firefox的debug显示 check is not defined
不是已经innerHTML进来了么，而且奇怪的是那个$page如果不加零的话显示的object element，望朋友解答！！！

------解决方案--------------------

这样呢
function check(node) {
var parameter = "page=" + node;
var nokia = ajax();
//alert(nokia);return;
nokia.open('POST',"process.php",true);
nokia.setRequestHeader('Content-Type','application/x-www-form-urlencoded');
nokia.send(parameter);
nokia.onreadystatechange = function () {
if(nokia.readyState==4 && nokia.status==200) {
document.getElementById('span1').innerHTML = this.responseText;
}
}
}
window.onload = check(node);


------解决方案--------------------

JScript code

window.onload = function (){   check(1);}function check(node) {    var parameter = "page=" + node;    var nokia = ajax();    //alert(nokia);return;    nokia.open('POST',"process.php",true);    nokia.setRequestHeader('Content-Type','application/x-www-form-urlencoded');    nokia.send(parameter);    nokia.onreadystatechange = function () {        if(nokia.readyState==4 && nokia.status==200) {            document.getElementById('span1').innerHTML = this.responseText;        }    }}<br><font color="#e78608">------解决方案--------------------<div class="clear">
                 
              
              
        
            </div></font>
