Question

i want to write a greasemonkey script that reloads every 10 sec. the same div of the same page. But i only know how to load a complete page into a div 🙁
of course my script below does’nt work…

function Ajax(){
var xmlHttp;
    try{    
        xmlHttp=new XMLHttpRequest();
    }catch (e){
        try{
            xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
        }catch (e){
            try{
                xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
            }catch (e){
                alert("No AJAX!?");
                return false;
            }
        }
    }
    xmlHttp.onreadystatechange=function(){
        document.getElementById('ReloadDIV').innerHTML=xmlHttp.responseText;
        setTimeout('Ajax()',10000);
    }
    xmlHttp.open("GET","#ReloadDIV",true);
    xmlHttp.send(null); 
}
window.onload=function(){
    setTimeout('Ajax()',10000);
}


<div id="ReloadDIV">Text Text</div>

Answer 1

I think one problem is the onreadystatechage which should be:

xmlHttp.onreadystatechange=function(){
if (xmlHttp.readyState==4 && xmlHttp.status==200)
    {
    document.getElementById('ReloadDIV').innerHTML=xmlHttp.responseText;
    setTimeout('Ajax()',10000);
    }
    }

readyState = 4 means request is finished and response is ready and the status = 200 is an OK response from the server
