Como minimizar el envió de datos con xmlhttp.open

Tengo estos datos que envio, son cerca de 100 valores de checkbox.

Código Javascript:

xmlhttp.open('GET',' checkbox.php?check1='+ document.getElementById('check1').checked + '&check3=' + document.getElementById('check3').checked + '&check4=' + document.getElementById('check4').checked + '&check5=' + document.getElementById('check5').checked + '&check6=' + document.getElementById('check6').checked + '&check7=' + document.getElementById('check7').checked + '&check8=' + document.getElementById('check8').checked + '&check9=' + document.getElementById('check9').checked + '&check10=' + document.getElementById('check10').checked + '&check11=' + document.getElementById('check11').checked + '&check12=' + document.getElementById('check12').checked + '&check13=' + document.getElementById('check13').checked + '&check14=' + document.getElementById('check14').checked + '&check15=' + document.getElementById('check15').checked + '&check16=' + document.getElementById('check16').checked + '&check17=' +

¿Te refieres a minimizar el código?
Puedes usar getElementsByTagName() para obtener todos los inputs y luego obtener sólo los que sean checkbox y concatenarlos. Algo como:

Código Javascript:

var valores = "";
for (i = 0, checks = formulario.getElementsByTagName("input"); chk = checks[i]; i++) {
    if (chk.type == "checkbox") {
        if (chk.checked) {
            valores += "&" + chk.name + "=" + encodeURIComponent(chk.value);
        }
    }
}

Hola:

Un par de apuntes... si vas a usar el método get, debes saber que existe un límite, que al escapar los datos se va incrementando... tal vez con un volumen grande de datos sea más aconsejable el método post; y sobre la concatenación, yo suelo inicializar "valores" como un array vacío, incrementándo ese array con push, y para pasar esos datos tan solo pongo valores.join("&"). simplemente es otra forma de hacer lo mismo.
