var nocache = 0;
function insert() {
// Optional: Show a waiting message in the layer with ID login_response
document.getElementById('insert_response').innerHTML = "Just a second..."
// Required: verify that all fileds is not empty. Use encodeURI() to solve some issues about character encoding.
var comto = encodeURI(document.getElementById('comto').value);
var comfrom = encodeURI(document.getElementById('comfrom').value);
var commen = encodeURI(document.getElementById('commen').value);

// Set te random number to add to URL request
nocache = Math.random();
// Pass the login variables like URL variable
http.open('get', 'insert.php?comto='+comto+'&comfrom=' +comfrom+'&commen='+commen+'&nocache=' +nocache);
http.onreadystatechange = insertReply;
http.send(null);
}
function insertReply() {
if(http.readyState == 4){ 
var response = http.responseText;
document.getElementById('insert_response').innerHTML = 'Your comment' +response+' has been posted.';
}
}

 

i need this script to auto refresh once it has run its query

 

var response = http.responseText;
document.getElementById('insert_response').innerHTML = 'Your comment' +response+' has been posted.';
}
}

 

the refresh needs to be somewhere in this ^^
