jQuery Google Maps question
Can anyone help me understand why the following code does not display any content in the second alert? Browsing to the same url that I pass to getJSON() produces output in my browser window.
<!DOCTYPE html>
<html&开发者_如何学JAVAgt;
<head>
<script src="http://code.jquery.com/jquery-latest.min.js"></script>
</head>
<body>
<script>
$.getJSON('http://maps.googleapis.com/maps/api/geocode/json?address=Chicago,IL&sensor=false',
function(json, textStatus) {
alert("textStatus:" + textStatus);
var out = '';
for (var i in json) {
out += i + ": " + json[i] + "\n";
}
alert(out);
//alert("JSON Data:" + json.results[0].formatted_address);
});
</script>
</body>
</html>
The problem was related to same origin policy. This post was very helpful. I have modified my code to use the Client-side Google Maps Geocoding API. Here is the working code:
<!DOCTYPE html>
<html>
<head>
<script src="http://code.jquery.com/jquery-latest.min.js"></script>
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
<script type="text/javascript">
var geocoder;
$(document).ready(function() {
geocoder = new google.maps.Geocoder();
});
function codeAddress() {
var address=$('#address').val();
geocoder.geocode( { 'address': address}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
$('#location').html('<p><b>Location:</b>' + results[0].geometry.location + '</p>');
} else {
alert("Geocode was not successful for the following reason: " + status);
}
});
}
</script>
</head>
<body>
<div>
<input id="address" type="textbox" value="Chicago,IL"/>
<input type="button" value="Geocode" onclick="codeAddress()" />
</div>
<div id="location">
</div>
</body>
</html>
It seems that your obj variable is undefined. Did you mean:
out += i + ": " + json[i] + "\n";
