toggle checkbox with javascript

Question

I want to uncheck a checkbox using javascript. I have one button which just unchecks the box and works fine:

function clear() {
document.getElementById(\"check\"         


        

Answer 1

I've never seen it done with a string "checked" before. Try with a boolean like:

function change() {
    if (document.getElementById("check").checked !== true) {
      document.getElementById("check").checked = true;
    } else {
      document.getElementById("check").checked = false;
    }
}

or easier

function change() {
    document.getElementById("check").checked = !document.getElementById("check").checked
}

Don't forget, switch is reserved, so use a different name, as I did with change()
