animate.js:

1. animate( properties [, duration ] [, easing ] [, complete ] )

properties:An object of CSS properties and values that the animation will move toward

duration(default: 400): A string or number determining how long the animation will run.

easing (default: swing):A string indicating which easing function to use for the transition.

complete:A function to call once the animation is complete

 1 (function(){
 2         var box = $('div.box');
 3             //fontSize = parseInt(box.css('font-size'),10);
 4 
 5         $('button').bind('click',function(){
 6             box.animate({
 7             'fontSize':'+=5',
 8             'width': '+=300'
 9             }, 500, 'swing', function() {
10                 console.log('completed');
11             });
12         })
13 
14     })();

.animate( properties, options )

options:A map of additional options to pass to the method.

options include: duration,easing,queue,specialEasing,step,progress,complete,done,fail,always

queue (default: true):A Boolean indicating whether to place the animation in the effects queue. If false, the animation will begin immediately. As of jQuery 1.7, the queue option can also accept a string, in which case the animation is added to the queue represented by that string.

step:A function to be called for each animated property of each animated element. This function provides an opportunity to modify the Tween object to change the value of the property before it is set.

 1 (function(){
 2         var box = $('div.box');
 3             //fontSize = parseInt(box.css('font-size'),10);
 4 
 5         $('button').bind('click',function(){
 6             box.animate({
 7             'fontSize':'+=5',
 8             'width': '+=300'
 9             }, {
10                 duration: 500,   //
11                 complete: function(){
12                     console.log('completed');
13                 },
14                 step: function () {
15                     console.log('the current font-size is: '+$(this).css('fontSize'));
16                 }
17             });
18         })
19 
20     })();

3.排队效果：多个.animate()连缀

 1 (function(){
 2         var box = $('div.box'),
 3             //fontSize = parseInt(box.css('font-size'),10);
 4             w = $(window).width()/2 - box.outerWidth()/2,
 5             h = $(window).height()/2 - box.outerHeight()/2;
 6 
 7         $('button').bind('click',function(){
 8             box.animate({
 9                 'left': w,
10                 'position': 'absolute'
11             })
12             .animate({
13                 'top': h
14             }, 2000);
15         })
16         
17 
18     })();

4.第二个参数包含了queue选项，把该选项设置为false即可让当前动画与前一个动画同时开始。

（1）

 1 (function(){
 2         var box = $('div.box');
 3             //fontSize = parseInt(box.css('font-size'),10);
 4 
 5         $('button').bind('click',function(){
 6             box.animate({
 7             'fontSize':'+=5',
 8             'width': '+=300'
 9             }, { duration: 500 })
10                 .animate({'top': '500'},{duration:3000, queue:false});//'queue:false' ,the second animate would execute at the same time as the one before that. 
11         });
12 
13     })();

（2）

 1 (function(){
 2         var box = $('div.box'),
 3             //fontSize = parseInt(box.css('font-size'),10);
 4             w = $(window).width()/2 - box.outerWidth()/2,
 5             h = $(window).height()/2 - box.outerHeight()/2;
 6 
 7         $('button').bind('click',function(){
 8             box.animate({
 9                 'left': w,
10                 'position': 'absolute'
11             })
12             .animate({
13                 'top': h
14             }, {duration:200, queue:false});
15         })
16     
17     })();
