Question

I am trying to create a js object, I want either the user passes in some json data or the objects properties are set by default as shown below. After that is all set, I finally want to call an init function that runs and does the work. Thanks for any help. I am not trying to create a jQuery plugin.

var PictureDialog = function (settings) {
    settings = {
        allowShortKey: true,
        prevID: null,
        prevCounterNumber: null,
        startValue: 0,
        nextValue: 1,
        init: function() {
            //Do work
           //Show dialog
        }
    },settings;

}

Would the call look something like this

PictureDialog({prevID:1}).init();

Not sure why you would need an init function at all. This is how I would do it:

(function () {
    var defaultSettings = {
        allowShortKey: true,
        prevID: null,
        prevCounterNumber: null,
        startValue: 0,
        nextValue: 1
    };
    PictureDialog = function (settings) {
        settings = settings || defaultSettings;
        //Do work
        //Show dialog
    };
})();

The outer function is just to make sure that defaultSettings doesn’t pollute the global scope.
