javascript ajax help
- by ngreenwood6
I have the following code.
var d3_ad = 1;
function displayD3Ad(){
var query_string = '?d3_ad='+d3_ad;
query_string += '&location='+escape(location);
//document.write('<iframe src="index.php'+query_string+'"></iframe>');
var data = httpRequest('http://localhost/test/index.php','GET',query_string);
document.write(data);
}
function httpRequest(strURL,type,query) {
var request = false;
if (window.XMLHttpRequest) {// Mozilla/Safari
request = new XMLHttpRequest();
} else if (window.ActiveXObject) { //Internet Explorer
request= new ActiveXObject("Microsoft.XMLHTTP");
}
request.open(type, strURL + query, true);
request.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
request.onreadystatechange = function() {
if (request.readyState == 4) {
return request.responseText;
}
}
request.send(null);
}
displayD3Ad();
now when it writes out the data it is saying undefined. It seems like it isnt returning the data. I looked in firebug and it completes and shows the response that shoudl be there. Any help is appreciated. I just need to set the data variable so that I can use it later on.
