Google Places API: json error Uncaught SyntaxError Unexpected token
I dont get why i get so many different errors. I'm using Google Places API for a test, and using simply an ajax query call with callback, i receive back the json but in CHrome browser i get
"Uncaught SyntaxError: Unexpected token :"
why the hell is that? I supposed Google does it right, and their json must be correct...so where could be the problem?
this is my code
$.ajax({
dataType: "json",
url: "https://maps.googleapis.com/maps/api/place/search/json?location=40.47,-73.58&radius=5000&sensor=false&key=MYOWN&name&callback=?",
success: function(data) {
console.log('success');
},
error: function(data) {
console.log('error');
}
});
You get this error, if a server returns plain JSON. As this is a cross-site request, jQuery has to use the JSONP-technique where the server-response is interpreted as script. This is the only way to do cross-site-requests in the browser.
The problem is that the server has to support JSONP and surround the JSON answer with a callback generated by jQuery. The response must look like that:

Server-Example with PHP:
<?php
header("Content-Type:text/javascript"); // avoid browser warnings
$request = new HttpRequest("http://programmingisart.com/json-data-source.php", HttpRequest::METH_GET);
$request->send();
$json_data = $request->getResponseBody();
// wrap the data as with the callback
$callback = isset($_GET["callback"]) ? $_GET["callback"] : "alert";
echo $callback."(".$json_data.");";
Client-Example with jQuery:
<div id="json-result"></div>
<script type="text/javascript">
$(document).ready(function() {
$.ajax({
dataType: "jsonp",
url: "jsonp-wrapper.php",
success: function(data) {
$("#json-result").html(JSON.stringify(data));
},
error: function() {
alert("error");
}
});
});
</script>
You can replace the PHP-code with any other server-platform and do the required steps.
