Question

IT IS SOLVED – WAITING TO MARK (stackoverflow delay)

There’s no error in firebug. I’ve done this before I just can’t figure out why it is not working. asyncFetchContent() is fired from elsewhere. contentController is created elsewhere.

function ContentController() {

}

ContentController.prototype.asyncFetchContent = function(){ 

         $.getJSON( '/content/TestContent.json', 
            function(data){
                contentController.displayContentCallback( data ); 
                } 
         );
}

ContentController.prototype.displayContentCallback = function( javascriptObject ){ 
    alert( "in callback");
    $( "#testID" ).html( javascriptObject.title );
}

Firebug will accept a breakpoint at the definition of displayContentCallback() and stop but then silently fails once you stepover. javascriptObject is undefined.

Thanks-in-advance,

From the manual:

Important: As of jQuery 1.4, if the JSON file contains a syntax error,
the request will usually fail silently. Avoid frequent hand-editing of
JSON data for this reason. JSON is a data-interchange format with
syntax rules that are stricter than those of JavaScript’s object
literal notation. For example, all strings represented in JSON,
whether they are properties or values, must be enclosed in
double-quotes. For details on the JSON format, see http://json.org/.

Does your JSON contain an error?
