jQuery Bounce Effect on click no jQuery UI

问题:

I cannot find a solution to an animation to make a div bounce, using just jQuery animations. Something like does not work:

$("#bounce").click(function() {
    $(this).effect("bounce", {
        times: 3
    }, 300);
});.​

I would prefer not to use jQuery UI or any external plugin, such as the easing one. A wobble effect would be just as good in my case, so either will do.

Here is an example, any help would be much appreciated! Thanks in advance

You could simply chain together some animate calls on the element like so:

$("#bounce").click(function() {
    doBounce($(this), 3, '10px', 300);   
});


function doBounce(element, times, distance, speed) {
    for(var i = 0; i < times; i++) {
        element.animate({marginTop: '-='+distance}, speed)
            .animate({marginTop: '+='+distance}, speed);
    }        
}

Use this function for damped bounces. Be sure to give the bouncing element a unique class if using the code without changes.

var getAttention = function(elementClass,initialDistance, times, damping) {
  for(var i=1; i<=times; i++){
      var an = Math.pow(-1,i)*initialDistance/(i*damping);
      $('.'+elementClass).animate({'top':an},100);
  }
  $('.'+elementClass).animate({'top':0},100);
}

$( "#bounce").click(function() {
	getAttention("bounce", 50, 10, 1.2);
});

#bounce {
    height:50px;
    width:50px;
    background:#f00;
    margin-top:50px;
    position:relative;
    border-radius: 50px;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="bounce" class="bounce"></div>

I use this simple plugin, jQuery-Shake, to shake or bounce an element without jQuery-UI.

$('#elementToBounce').shake({direction: up, distance:10, speed: 75, times: 3})

For a vertical bounce you can try something like this:

function bounce(element, distance, speed){
 var bounce_margin_top = $(element).css("margin-top")
 $(element).css("margin-top", "-="+distance)

 $(element).show().fadeIn(200).animate({
    "margin-top": bounce_margin_top
 }, {
     duration: speed,
     easing:   "easeOutBounce"
 })
}

I usually use jQuery animate. For your specific question, it could look like this:

The HTML:

<div id="bounce"></div>

The CSS:

#bounce {
height:50px;
width:50px;
background:#333;
margin-top:50px;
position:relative;
}

And finally, the jQuery:

$( "#bounce" ).click(function() {
for (var i=1; i<=3; i++) {
$(this).animate({top: 30},"slow");
$(this).animate({top: 0},"slow");
     }
});
