布尔值取1/0以及true / false

Question

I'm using the following code. Is there a way I can re-write it so the Boolean (or any other method) will take 1 and 0 as well? Right now it only takes true/false as values. Can I do this without checking for 1/0 and then turning that into true/false? Eg give a true or false just by using 1/0 as values.

$("#toggle").toggles({
  drag: true,
  click: true,
  text: {
    on: "ON",
    off: "OFF"
  },
  on: Boolean($("#container").attr("data-active")),
  animate: 150,
  easing: "swing",
  checkbox: null,
  clicker: null,
  width: 80,
  height: 16,
  type: "compact"
});

You pretty much never need Boolean() in JavaScript.

Simply use !!$("#container").attr("data-active") to convert the value to a boolean (negating a value converts it to boolean, negating it again undoes the negation)

Also, I would rather use $("#container").data("active") - by using data() , jQuery automatically converts the strings true / false to a boolean.
