Question

Is there a way in JavaScript to call a function without parentheses?

For example in jQuery:

$('#wrap').text("asdf"); will work and so will $.ajax(ajaxOptions);

I’m mapping a function (class) to window.$ that has a set of functions I want to be able to call with or without parentheses. Like jQuery.

Here’s a code example:

function Test(asdf) {
  this.test = function(testVar) { return testVar + ' asdf'; }
}

And I map Test() to $:

window.$ = new Test();

I have to call the function (class) like this:

$('asfd').test('ASDF');

But I want to be able to call it like this:

$.test('asdf');

You can try something like this

var test = {
    method1 : function(bar) {
        // do stuff here
        alert(bar);
    },
    method2 : function(bar) {
        // do stuff here
        alert(bar);
    }
};

test.method1("foo");
test.method2("fooo");
