Question

I fear I may be losing my marbles today, because I don’t know how to do what I want to. I want a custom prompt that I can call from any of my other JavaScript functions. I don’t know how to get this work, even though it feels like I’ve done it a hundred times.

Here is an example

var modal = function() {

    var prompt = function(msg) {
        // custom prompt builder here... let's return hard coded for example's sake
        return true;
    };

}();

var items = function() {
    var init = function() {

        $('.delete').click(function() {
            var confirm = modal.prompt('Are you sure you wanna delete that pal?');
        });

    };    


    $(document).ready(init);    
}();

What I want to be able to do is call the prompt method of modal, and get a return value based on the user input. Now this, I can do, but I am having problems calling the inner method. I want to group these together because I will probably have a custom modal alert() too.

Please don’t suggest the built in JavaScript OK/Cancel as I gotta do this custom.

Many thanks!

From the way you call modal.prompt, it appears you want the anonymous function to return an object that will be stored in modal:

var modal = (function() {
    // various private fields & methods here
    ...
    // the public interface
    var self = {
        prompt: function(msg) {
            // custom prompt builder here... let's return hard coded for example's sake
            return true;
        }
    };
    return self;
})();
