I'm having problems connecting to my server to check credentials for my phone application, in which I'm using phonegap to develop it.
I've already checked out these questions, but they're not giving me what I'm looking for
I've read up on the subject and have made multiple sites using get requests, so I have a pretty good understanding on the matter, I'm just not sure what's going on.

Here's what my code looks like:
login.onclick = function() {
var req = new XMLHttpRequest();
req.open('GET', 'myServer'+username.value+".json", true);
req.send();
req.onreadystatechange = function() {
if (req.readyState == 4) {
if( (req.status == 200) || (req.status == 0) ) {
var json = JSON.parse(req.responseText);
if(json.length > 0) {
if((json[0]["username"] == username.value) && (json[0]["phoneCred"] == password.value)){
localStorage.setItem("loggedIn",username.value);
location.reload();
}
else {
alert("Incorrect password");
}
}
else {
alert("Incorrect username");
}
}
else {
alert("Error talking to server");
}
}
}
};
I added the req.status == 0 into the one if, and now my button is completely unresponsive, I was at least getting the alert that I wasn't talking to the server. If anyone has any insight, it would be much appreciated!
okay so i had a couple of errors in my code, in which i fixed so here's my updated code:
login.onclick = function() {
var req = new XMLHttpRequest();
req.open('GET', 'myServer'+username.value+'.json', true);
req.send();
alert('myServer'+username.value+'.json');
req.onreadystatechange = function() {
if (req.readyState == 4) {
if( (req.status == 200) || (req.status == 0) ) {
//alert(req.responseText.length);
alert(req.responseText);
if(req.responseText.length > 0) {
var json = JSON.parse(req.responseText);
if( (json[0].username == username.value) && (json[0].phoneCred == password.value) ){
localStorage.setItem("loggedIn",username.value);
location.reload();
}
else {
alert("Incorrect password");
}
}
else {
alert("Incorrect username");
}
}
else {
alert("Error talking to server");
}
}
}
};
i have two phone on which i've been testing on, and it worked on my galaxy note, but not on my galaxy s4 if that might be a hint towards anything.
i also changed my access tag in my xml file to
<access origin=".*" />
after i did some reading from
Phonegap + Android status=0 returned from webservice
phonegap XMLHttpRequest responseText empty with android but contain data in iphone
and
Empty responseText from XMLHttpRequest
but my galaxy s4 still doesnt seem to receive any data from the server. It may be the same origin policy or some setting for internet access that I'm unsure about. If anyone has any suggestions, I would be very appreciative.
