How can jQuery do method chaining? [duplicate]

Answer 1

function funcA(arg1) {

    var enclosedVariable= arg1;

    return {
       funcB: function () {
          alert(enclosedVariable);
       }
    };
}

Here is a quick and dirty example. ^^

funcA takes an argument and saves it then returns an object containing a single function. It has been "enclosed" and now funcB has access to this.

Technically you don't even have to save it... arg1 is available to funcB as well.
