Question

I suppose this is an easy problem to solve, it’s just a little bit tricky to google. I have this function that random generates some numbers for 1 second until it reaches the real value (number()), just a flashy effect. However, the value is a 7 digit number and I want to separate it with commas. I have working functions for both of the functions but I dont know how to make them work together. I’ve tried to add the digits() function to my number() function but I cant get the commas to show while the number is random generating, only when it’s done.

This is my number() code:

(function($){
    $.fn.extend({
        number: function(options) {
            if ( ! this.length)
                return false;

            this.defaults = {
                endAt: 90,
                numClass: 'autogen-num',
                interval: 65  // ms
            };
            var settings = $.extend({}, this.defaults, options);

            var $num = $('<span/>', {
                'class': settings.numClass
            });

            return this.each(function() {
                var $this = $(this);

                // Wrap each number in a tag.
                var frag = document.createDocumentFragment(),
                    numLen = settings.endAt.toString().length;
                for (x = 0; x < numLen; x++) {
                    var rand_num = Math.floor( Math.random() * 10 );
                    frag.appendChild( $num.clone().text(rand_num)[0] )
                }
                $this.empty().append(frag);

                var get_next_num = function(num) {
                    ++num;
                    if (num > 9) return 0;
                    return num;
                };

                // Iterate each number.
                $this.find('.' + settings.numClass).each(function() {
                    var $num = $(this),
                        num = parseInt( $num.text() );

                    var interval = setInterval( function() {
                        num = get_next_num(num);
                        $num.text(num);
                    }, settings.interval);

                    setTimeout( function() {
                        clearInterval(interval);
                    }, settings.duration * 1000 - settings.interval);
                });

                setTimeout( function() {
                    $this.text( settings.endAt.toString() );
                }, settings.duration * 1000);
            });
        }
    });
})(jQuery);

And this is my digits() code:

$.fn.digits = function(){ 
    return this.each(function(){ 
        $(this).text( $(this).text().replace(/(\d)(?=(\d\d\d)+(?!\d))/g, "$1,") ); 
    })
}

Thanks in advance!

The numbers function replaces only one number at the time, and it relies on the numbers being numbers, so replacing them during the loop with a string containing commas is’nt really an option!

I rebuilt the numbers function to handle a string instead. No idea if it’s what you’re looking for, but it’s the closest I could get:

(function($){
    $.fn.numAnim = function(options) {
        if (!this.length) return false;

        this.defaults = {
            endAt: 2060,
            numClass: 'autogen-num',
            duration: 1,   // seconds
            interval: 30  // ms
        };
        var settings = $.extend({}, this.defaults, options),
            $this = this,
            interval = setInterval(function() {
                var numb = parseInt(Math.random() * (Math.pow(10, settings.endAt.toString().length)));
                $this.text(numb.toString().replace(/(\d)(?=(\d\d\d)+(?!\d))/g, "$1,"));
            }, settings.interval),
            timer = setTimeout(function() {
                clearInterval(interval);
                $this.text(settings.endAt.toString().replace(/(\d)(?=(\d\d\d)+(?!\d))/g, "$1,"));
            }, 1000*settings.duration);
    }
})(jQuery);


$("#number").numAnim({
    endAt: 4103518,
    duration: 1
});​
