我最近有一个网站播出,无法让用户刷新页面(因此,ajax),无法让聊天工作。但另一端的人仍然需要刷新才能看到最新消息。我们在同一个房间,所以我可以看到聊天是否刷新;它没有,这是代码
<script type="text/javascript">
var scroller = function(){
posts = document.getElementById("posts");
posts.scrollTop = posts.scrollHeight;
}
var menu = 3;
var checksum = function(){
if (menu == 3){
document.getElementById('smileys').style.display="block";
document.bob.smileyhider.innerHTML="−";
menu=1;
}
else {
document.getElementById('smileys').style.display="none";
document.bob.smileyhider.innerHTML="+";
menu=3;
}
}
//Chat ajax loader
var updater = 10;
function update(){
var xhr;
if(updater < 200){ updater = 200 }
if (window.XMLHttpRequest){ xhr = new XMLHttpRequest(); }
else { xhr = new ActiveXObject('Microsoft.XMLHTTP'); }
xhr.onreadystatechange = function(){
if (xhr.readyState==4 && xhr.status == 200){
document.getElementById('posts').innerHTML = xhr.responseText;
}
}
setTimeout(update, (++updater)*10);
xhr.open("GET","chatlog<?php echo date("d");?>.log",true);
xhr.send(null);
}
</script>

var updater = 3000;
function update(){
var xhr;
if(updater < 200){ updater = 200 }
if (window.XMLHttpRequest){ xhr = new XMLHttpRequest(); }
else { xhr = new ActiveXObject('Microsoft.XMLHTTP'); }
xhr.onreadystatechange = function(){
if (xhr.readyState==4 && xhr.status == 200){
document.getElementById('posts').innerHTML = xhr.responseText;

}
xhr.open("GET","chatlog<?php echo date("d");?>.log",true);
xhr.send(null);
}
setInterval(update, updater);
