Something like

    var map = {};
    var varNamePrefix = 'data';
    map = $.map(data, function(item, i) {
        return getProperties(item, varNamePrefix);
    });
});

service.getSomething(function(data) {
    var map = {};
    var varNamePrefix = 'something';
    map = $.map(data, function(item, i) {
        return getProperties(item, varNamePrefix);
    });
});

function getProperties(item, varNamePrefix) {
    var ret = {};
    ret.key = item[varNamePrefix + '1'];
    ret.value = item[varNamePrefix + '2'];
    return ret;
}

Basically, you could use a function that takes a property prefix and uses it to form the actual property names to get from items.
