使用示例代码：
<!DOCTYPE html>
<html>
<head>
<title>category</title>
</head>
<script type="text/javascript" src="jquery-1.10.2.min.js"></script>
<script type="text/javascript" src="images/categorySourceData.js"></script>
<script type="text/javascript" src="category.min.js"></script>
<script type="text/javascript">
$(document).ready(function () {
//创建一个新的分类选择器
//可选择配置信息,默认值，说明：
//sourceData:{ list:[] }, //array:分类数据源，格式参考：images/categorySourceData.js
//button:"span_button", //id:单击此按钮弹出分类选择层
//buttonIcon:"b_buttonIcon", //id:按钮图标元素
//textView:"span_textView", //id:选择的分类名称在这里显示
//textDefault:"\u8BF7\u9009\u62E9\u5206\u7C7B", //string:没有选择分类时的提示文字
//popLayout:"div_popLayout", //id:分类选择层
//cateView:"ul_cateView", //id:分类列表容器
//onChange:null, //event:当用户选中最后一级节点时触发
//onSelect:null //event:当用户单击一个分类时触发，此事件在onChange之前触发
var category1 = new category({ sourceData: categorySourceData, onSelect: function () {
category1.SetCategoryText();
},
onChange: function (cid, level, text) {
//可以通过selectItems属性当前选中的分类信息
//selectItems属性示例：[{ cid: 1, level:1, text:'教育专区' }, { cid: 11, level:2, text:'外语学习'}];
var selectCids = "";
for (var i = 0; i < category1.selectItems.length; i++) {
if (i == 0) {
selectCids = category1.selectItems[i].cid;
} else {
selectCids += "," + category1.selectItems[i].cid;
}
}
$("#divResult").text("您选择的分类编号为：" + selectCids);
}
});
//可以通过设置selectItems属性，设定初始选项
category1.selectItems = [{ cid: 1 }, { cid: 11}];
//设置完成后通过load方法加载
category1.load();
});
