Grails dealing checkbox without GSP

Question

I'm not using GSP files and I'm getting nulls on my params.data to return back to my application as JSON. My problem is on the grails or javascript?

javascript

var data = $('input:checkbox[name=grid-checkbox]:checked').map(function() { return $(this).val(); }).toArray();
$.ajax({
    type: "GET",
    data: data,
    crossdomain: true,
    url: "http://..../food",
    success: success,
    error: fail
});

grails

def food() {
    def result = []
    def checkbox = params.data
    def b
    println params.data //null
    checkbox.each {
        b = Food.findAllById(checkbox.it).collect { Food food ->
            result << [id: food.id,
                    foodType: food.foodType
            ]
        }
    }
    return formatAndRender("JSON", params.callback, result)
}

Your data is null because no data key exists in the params map.

data: data should be a valid key value pair like

data: "data=" + data
