I want to be able to change the content of a certain div according to the time of the user. For example, if it's 5am, certain content would show. If it's 6am, another content shows.

John Doe 8am-4pm (changes to that name when its 8am-4pm)
John Doe 5pm-6pm (changes to that name when its 5pm-6pm)
John Doe 7pm-8pm (changes to that name when its 7pm-8pm)

I was using .php but it doesn't work. Anyone know of something similar?

Any help is appreciated!

• javascript
• jquery
• rotation
• dynamic-content

• Can you expand on what "doesn't work" about the rotator you're using? – baraboom Commented Jun 8, 2011 at 17:25
• Can you user server side code? – Jared Commented Jun 8, 2011 at 17:27
• In that it changes by the hour switch_every: "hour" and also it doesn't show any content. Here is my attempt: wsul./new_build/rotator.html – Francheska Commented Jun 8, 2011 at 17:30
• js/jquery.rotator.0.1.js is not found. Try pointing to the right file? – matchew Commented Jun 8, 2011 at 18:17
• That is true. I am no longer using this sample as it only works by day, I needed it by the hour, which the answers helped! Thank you – Francheska Commented Jun 8, 2011 at 19:17

very tersely

//initialize date object
var d = new Date();
var currentHour = d.getHours(); //note 0-23

if (currentHour < 6) 
 { 
     $('div').append('Before 6am');
  }
else if (currentHour == 7)
{
   $('div').append('7am');
}
else {
   $('div').append('Time Now' + d.getHours() + ':' + d.getMinutes()); 
  }

live example: http://jsfiddle/9dUJ6/

expand with else if

so too does w3schools http://www.w3schools./jsref/jsref_obj_date.asp

Something like this should be a good start for you:

$(function(){

    $('#timeperiod1').mood({
        range: [1, 7] // hours
    });
    $('#timeperiod2').mood({
        range: [7, 12] // hours
    });
    $('#timeperiod3').mood({
        range: [12, 24]  // hours
    });
});

// the jquery plugin
// TODO: add end of day re init
//       add min/sec along with hours
$.fn.mood = (function(){
    var Mood = function(el, opts){
        this.el = $(el);

        this.range = { bottom: opts.range[0]*1, top: opts.range[1]*1 };
        this.init();
    };
    Mood.prototype = {
        init: function(){
            this.initTime = this.checkTime(); // 1, 0, -1

            this.initTime == 0 ? this.show() : this.hide();
            this.start();
        },
        start: function(){
            var t = new Date(), 
                showDate = new Date(t), 
                hideDate = new Date(t), 
                h = t.getHours(), hide = false, show = false;

            if(this.initTime < 0) {// time has not yet e
                showDate.setHours(this.range.bottom);
                showDate.setMinutes(0);
                show = true;

            }
            if(this.initTime <= 0){
                hideDate.setHours(this.range.top);
                hideDate.setMinutes(0);
                hide = true;
            }
            debugger;
            show && setTimeout($.proxy(this.show, this), Math.ceil(showDate.getTime()-t.getTime()));
            hide && setTimeout($.proxy(this.hide, this), Math.ceil(hideDate.getTime()-t.getTime()));
        },

        checkTime: function(){
            var t = new Date(), h = t.getHours();
            if(h >= this.range.bottom && h <= this.range.top)
                return 0;
            if(h < this.range.bottom)
                return -1;  
            if(h > this.range.top)
                return 1;  
        },
        show: function(){
            this.el.show('slow');
        },
        hide: function(){
            this.el.hide('slow');
        }

    };

    return function(opts){
        return this.data('rotateMood', new Mood(this, opts));    
    };
})();
