jQuery Raty星级评分插件使用方法
使用jQuery Raty，可以很方便的在页面上嵌入一个评分组件，如下所示：
使用方法很简单，首先从https://github.com/wbotelhos/raty下载raty的源代码（依赖于jquery）
然后在页面中引入相应的js文件、css文件、图片资源，在需要添加评分组件的元素上（比如span标签）添加下面的jquery代码即可：
$('span').raty();
以上为jQuery Raty的缺省使用方法，此外，该组件还支持丰富的传入参数和回调函数，例如：
设置jQuery Raty的初始评分：
评分回调函数
如果需要根据后台动态设置初始评分，可以使用回调函数实现。例如使用div中的data-attribute属性：
<div data-score="1"></div>
$('div').raty({ score: function() { return $(this).attr('data-score'); } });
还可以改变星星的个数：
$('div').raty({ number: 10 });
只读模式：
$('div').raty({ readOnly: true, score: 3 });
点击事件：
$('div').raty({ click: function(score, evt) { alert('ID: ' + this.id + "\nscore: " + score + "\nevent: " + evt); } });
路径：
变更图标保存的位置，所有图标需要位于同一目录下，路径结尾的/不添加也可以
<div data-path="assets/images"></div>
$('div').raty({ path: function() { return this.getAttribute('data-path'); } });
取消评分：
$('div').raty({ cancel: true });
全局改变设置：
你可以全局更改上述提到的所有设置 $.fn.raty.defaults.OPTION = VALUE;. 该语句必须添加在插件绑定之前。
$.fn.raty.defaults.path = assets;
$.fn.raty.defaults.cancel = true;
