Using JavaScript to manipulate HTML input (checkbox) elements via type instead of name

Question

I am implementing an HTML form with some checkbox input elements, and I want to have a Select All or DeSelect All button. However, I do not want to rely on the name

Answer 1

Every input element has an attribute, type, which for checkboxes is "checkbox" so you could try something like this:

for (var i = 0; i < document.myForm.elements.length; i++) {
    if (document.myForm.elements[i].type == "checkbox") {
        document.myForm.elements[i].checked = true;
    }
}
