Can someone please help with parsing some data from a json string. Here is the JSON data:
data = "{\"centerLatitude\":-41.22766,\"centerLongitude\":174.812761,\"mapTypeId\":\"google.maps.MapTypeId.ROADMAP\",\"zoom\":18}"
In my AJAX code, I have the following code:
success: function (mapDetailsData) {
var data = jQuery.parseJSON(mapDetailsData);
alert(data.centerLatitude);
alert(data.centerLongitude);
}
I am getting the following error in the console:
Uncaught SyntaxError: Unexpected token o
If I specify the JSON data as follows:
var data = jQuery.parseJSON('{\"centerLatitude\":-41.22766,\"centerLongitude\":174.812761,\"mapTypeId\":\"google.maps.MapTypeId.ROADMAP\",\"zoom\":18}');
alert(data.centerLatitude);
alert(data.centerLongitude);
The alert
displays the correct data.
How do I need to write the ajax code to display the correct values of centerLatitude
and centerLongitude
?
Thanks in advance.
Assuming that you set the datatype
parameter to json
(or leave it at the default setting and it recognises the JSON format by itself) then jQuery will automatically deserialise the response for you. The error you see is normally an indication that you are trying to parse twice. Try this:
success: function (mapDetailsData) {
alert(mapDetailsData.centerLatitude);
alert(mapDetailsData.centerLongitude);
}
