1. Percentage Loader（推荐）
一款轻量的 jQuery 进度条插件，以百分比的形式呈现加载进度，同时显示已加载的内容大小。
1.1. 起始百分比：：调整 progress
var $topLoader = $("#topLoader").percentageLoader({width: 256, height: 256, controllable : true, progress : 0.01, onProgressUpdate : function(val) {
var totalKb = 3000; /// more bit more time

2. CSS3 Loading Spinners Without Images
2.0.1. CSS Transforms
CSS transform (in Firefox 3.5+ and Webkit-based browsers) has a whole bunch of interesting functions, such as rotation, translation, scaling and skewing. To learn more about the different functions, check out the Mozilla developer center overview of CSS transform. After playing around with chaining different transforms and seeing the effect, I found out something interesting:
transform:rotate(45deg) translate(0, -35px);
If you rotate first, and then translate (move), it will move along the rotated axis. The above code translates a block to the top-right corner (45 degrees). (the gray div is not transformed while the black one is.)
Using this, I could rotate and translate a bunch of divs to create loading spinners (though this one doesn’t spin yet!):
In this example, each div is rotated an additional 45 degrees. The first one is not rotated, the second one is rotated 45 degrees, the one after that 90 degrees, and so forth. Additionally, each div has increased opacity to make it look like most loading spinners.
2.0.2. Animation
Webkit supports CSS animations, but these are continuous while most loading spinners are not. On the left side is a spinner animated with CSS animation (only works in Safari and Chrome), on the right there’s one animated with a small bit of JavaScript to look like regular loading spinners:
The code for the CSS animation is fa
3. Ajax Style Loading Animation in CSS3 ( no Images )
Facebook style
HTML
<div id=‘facebook‘ > <div id=‘block_1‘ class=‘facebook_block‘></div> <div id=‘block_2‘ class=‘facebook_block‘></div> <div id=‘block_3‘ class=‘facebook_block‘></div></div>
CSS
#facebook{ margin-top:30px; float:left;}.facebook_block{
background-color:#9FC0FF; border:2px solid #3B5998; float:left; height:30px; margin-left:5px; width:8px; opacity:0.1; -webkit-transform:scale(0.7); -webkit-animation-name: facebook; -webkit-animation-duration: 1s; -webkit-animation-iteration-count: infinite;
-webkit-animation-direction: linear; }#block_1{ -webkit-animation-delay: .3s; }#block_2{
-webkit-animation-delay: .4s;}#block_3{ -webkit-animation-delay: .5s;}@-webkit-keyframes facebook{
0%{-webkit-transform: scale(1.2);opacity:1;} 100%{-webkit-transform: scale(0.7);opacity:0.1;}}
4. PageLoading - jQuery plugin

6. jQuery Circular Progress Bar
这款环形进度条加载插件可以非常灵活的定制外观、加载速度以及设置特定的进度值。
7. jQuery Progress Bar
一款非常简单的百分比进度条插件，可以参数灵活的控制百分比的增减，有动画效果。
