Check if Checkbox is checked

I have created checkboxes using CourseBuilder. Now I'm writing a function to check if one of e.g. four checkboxes is checked. How do I do this?

function isACheckboxChecked(form){
for(f=0;f<form.length;f++){
if(form[f].type=="checkbox" && form[f].checked){
return true;
}
}
return false;
}
