Empty responseText from XMLHttpRequest
- by PurplePilot
I have written an XMLHttpRequest which runs fine but returns an empty responseText.
The javascript is as follows:
var anUrl = "http://api.xxx.com/rates/csv/rates.txt";
var myRequest = new XMLHttpRequest();
callAjax(anUrl);
function callAjax(url) {
myRequest.open("GET", url, true);
myRequest.onreadystatechange = responseAjax;
myRequest.setRequestHeader("Cache-Control", "no-cache");
myRequest.send(null);
}
function responseAjax() {
if(myRequest.readyState == 4) {
if(myRequest.status == 200) {
result = myRequest.responseText;
alert(result);
alert("we made it");
} else {
alert( " An error has occurred: " + myRequest.statusText);
}
}
}
The code runs fine. I can walk through and I get the readyState == 4 and a status == 200 but the responseText is always blank.
I am getting a log error (in Safari debug) of Error dispatching: getProperties which I cannot seem to find reference to.
I have run the code in Safari and Firefox both locally and on a remote server.
The URL when put into a browser will return the string and give a status code of 200.
I wrote similar code to the same URL in a Mac Widget which runs fine, but the same code in a browser never returns a result.
