jQuery Ajax

Original.js

/**
 * hardcoded and rigid
 */
function ajaxGeocode(data) {
    requestAJAX = jQuery.ajax({
        method: 'POST',
        url: 'php/ajax/geocode.php',
        dataType: 'json',
        data: { ajax : data }
    });

    requestAJAX.done(function(response) {
        debug(response)
    });

    requestAJAX.fail(function(response) {
        console.log('ajax failure')
    }); 
}

Refactored.js

function ajaxGeocode(data) {
    return jQuery.ajax({
        method: 'POST',
        url: 'php/ajax/geocode.php',
        dataType: 'json',
        data: { ajax : data }
    });
}

/**
 * handle ajax response (in another part of the code structure)
 */
ajaxGeocode(addressInformation).done(function(response) {
    debug('RESPONSE IS:')
    debug(response)
}).fail(function(response) {
    debug('Error has occurred: ' response)
})
