Question

I’m making a JavaScript object with literal notation, but I’m not sure how to make the object receive parameters like this:

hi.say({title: "foo", body: "bar"});

instead of hi.say("foo", "bar");.

Current code:

var hi = {
    say: function (title, body) {
        alert(title + "\n" + body);
    }
};

The reason why I want that is because I want people to be able to skip the title and just put the body, and do the same for many other parameters.

So that’s why I need something like how we can use jQuery functions’ parameters {parameter:"yay", parameter:"nice"}

P.S. I’m open too for modification of the current method – keeping in mind that there would be many parameters, some required and some optional, and which cannot be ordered in a specific way.

Answer 1

There is no special parameter syntax for that, just make the function take a single parameter, and that will be an object:

var hi = {
  say: function(obj) {
    alert(obj.title + "\n" + obj.body);
  }
}
