Using this code I have this issue:

$.fn.dxwShow = function (options)

{

    console.log(typeof(options));

    dxwShowSetOptions(options);



    setInterval(function(){

        dxwShowChange();

    }, dxwShowOptions.time);

};



var dxwShowOptions = {

    "transition" : "SlideToggle",

    "time": 1000

};



var dxwShowStatus = {

    current : 0

};



function dxwShowSetOptions(options)

{

    console.dir(typeof(options));



    dxwShowOptions = Object.create(dxwShowOptions, options);

}



function dxwShowChange()

{

    console.log(dxwShowOptions);

};



$(function()

{

    options = {

        "time": 700,

        "debug" : true

    };



    $("#dxwShow").dxwShow(options);

});

I want to update dxwShowOptions and so I use Object.create passing first the object I wanna copy and so the object containing the new parameters. Where is the mistake?

PS :Chrome say that the object is at the Object.create line.

Object.create takes a map of property descriptors. options is not such a list.

See https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/Object/create

If you wanted to still use Object.create, you'd need to modify options to be something more like

var options = {

    time: {

        enumerable: true,

        configurable: true,

        writable: true,

        value: 700

    },

    debug: {

        enumerable: true,

        configurable: true,

        writable: true,

        value: true

    }

};

But probably you want to use something more like _.extend.
