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;
