Question

I have in a situation where I cannot use Jquery UI for a reason. I am trying to do get Jquery UI Pulsate Effect without using Jquery UI. Similar to this link, http://docs.jquery.com/UI/Effects/Pulsate. I have search a lot but couldn't find anything.

I don't know what original UI code looks like, but this is super simple implementation using animate function:

$.fn.pulse = function(options) {

    var options = $.extend({
        times: 3,
        duration: 1000
    }, options);

    var period = function(callback) {
        $(this).animate({opacity: 0}, options.duration, function() {
            $(this).animate({opacity: 1}, options.duration, callback);
        });
    };
    return this.each(function() {
        var i = +options.times, self = this,
        repeat = function() { --i && period.call(self, repeat) };
        period.call(this, repeat);
    });
};

$("div").click(function() {
    $(this).pulse({times: 4, duration: 500});
});

Check the demo below or this JsFiddle.

$("div").click(function() {
    $(this).stop().pulse({times: 4, duration: 300});
});

$.fn.pulse = function(options) {
    
    var options = $.extend({
        times: 3,
        duration: 1000
    }, options);
    
    var period = function(callback) {
        $(this).animate({opacity: 0}, options.duration, function() {
            $(this).animate({opacity: 1}, options.duration, callback);
        });
    };
    return this.each(function() {
        var i = +options.times, self = this,
        repeat = function() { --i && period.call(self, repeat) };
        period.call(this, repeat);
    });
};

div {background-color: green; padding: 20px; display: inline-block;}
