If all your wanting to do is to trigger some code depending on if the checkbox is selected or not, here you go:

var theButton = document.getElementById("Button1");
var theCheckBox = document.getElementById("Checkbox1");
theButton.onclick = function () {
    if (theCheckBox.checked) {
        //Code that executes when checkbox is selected
    }
    else {
        //Code that executes when checkbox is not selected
    }
}
