Trying to work with this JSON file: The "data" array is empty most of the time.
Encountering cross-domain issues, receiving an 'Access-Control-Allow-Origin' error message.
$.ajax({
url : "http://www.oref.org.il/WarningMessages/alerts.json",
type : 'GET',
crossDomain: true,
data : "json",
dataType : "json",
success : function(res) {
console.log('res',res);
}
});
Attempted JSONP methods to retrieve the data with no luck. Can anyone assist in fixing the code?
This solution addresses the issue you're encountering. In order for JQuery to recognize it as an Ajax request, the dataType needs to be set to "jsonp". This code has been tested successfully with the latest version of JQuery 2.1.1.
$.ajax({
url : "http://www.oref.org.il/WarningMessages/alerts.json",
type : 'GET',
crossDomain: true,
data : "json",
dataType : "jsonp",
success : function(response) {
console.log('response', response);
}
});
JSONP offers a clever workaround for bypassing the same domain policy imposed by XMLHttpRequest. To implement JSONP, simply replace "json" with "jsonp" in the dataType attribute of your AJAX call:
$.ajax({
url: "http://www.example.com/alerts.json",
type: 'GET',
crossDomain: true,
data: "json",
dataType: "jsonp",
success: function(response) {
console.log('response', response);
}
});
Alternatively, you can create a server-side script (in php, java, etc.) that fetches the json data and serves it back to the client. Then, modify the jquery script to fetch the json data from your own server.
Here's an example php code snippet:
header("Content-Type:application/json");
echo file_get_contents("http://www.example.com/alerts.json");
