I am just getting my feet wet where JavaScript Prototyping is involved, and I am having some trouble.

I need to create a `_LEAVE` object from a `LEAVE` prototype for a system I am working on based on a prototype object. The `_LEAVE` object has a function named `Ready`, which should fire when the document is ready. The system already has similar functionality in some of it's older code, and I am trying to keep it uniform.

Here is the code I am trying, but I keep getting an error:

```
var LEAVE = function () {

}

$(document).ready(function () {
    _LEAVE.Ready();
});

var _LEAVE = function (params) {

    this.Ready = function () {
        alert ("Leave Ready");
    };
}

_LEAVE.prototype = new LEAVE();

```

Error:

> 
> SCRIPT438: Object doesn't support property or method 'Ready' 
>  leave.js, line 6 character 5
> 
> 
> 

I'm not sure where I am going wrong, as this seems to be what is happening in other parts of the system. At least, something similar is happening, but I am struggling to wrap my mind around the old code...

Would appreciate any advice anyone could give me! :-)
