Google Chrome + Ajax
- by teehoo
Im writing an ajax web app that uses Comet/Long Polling to keep the webpage up to date, and I noticed in Chrome, it treats the page as if its always loading (icon for the tab keeps spinning).
I thought this was normal for Google Chrome + Ajax because even Google Wave had this behaviour.
Well today I noticed that Google Wave no longer keeps the loading icon spinning, anyone know how they fixed this?
Here's my ajax call code
var xmlHttpReq = false;
// Mozilla/Safari
if (window.XMLHttpRequest) {
xmlHttpReq = new XMLHttpRequest();
}
// IE
else if (window.ActiveXObject) {
xmlHttpReq = new ActiveXObject("Microsoft.XMLHTTP");
}
xmlHttpReq.open('GET', myURL, true);
xmlHttpReq.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
xmlHttpReq.onreadystatechange = function() {
if (xmlHttpReq.readyState == 4) {
updatePage(xmlHttpReq.responseText);
}
}
xmlHttpReq.send(null);
