页面上一些基础数据或者其他页面经常用到部分，可以独立出来做成小组件，组件预留调用入口，需要的页面直接调用即可。
如图，页面中的展示分类和搜索标签在多个页面重复使用，可以将这部分内容独立出来，做成组件，供后续开发调用：
classify_search_tag.html文件如下，其中包含HTML节点和Jquery代码；
<!--
展示分类与搜索标签组件使用说明：
1.新增时父页面调用方法：页面加载时调用 goodsClassifyAndSearchTag.getFirstLevelClassify();/** 初始化一级展示分类 **/
2.编辑时父页面调用方法：页面加载时调用 goodsClassifyAndSearchTag.getClassifyAndSearchTag(String classifys);
ShowClassifyList类型json串，可参考 \js\standard_v2\group\group_edit.js 该方法 groupGoodsObj.getEditClassify();
3.返回页面选中的展示分类和搜索标签，调用 goodsClassifyAndSearchTag.returnSelectedClassifyAndTag();
注意事项：可能会出现js冲突问题，父页面的js最好在文件顶部加载

调用页面的HTML文件中该模块的位置用velocity引用该组件：
#parse("/classify_search_tag.html")
调用页面的js文件中，调用入口方法即可：
新增调用
$(function () {
goodsClassifyAndSearchTag.getFirstLevelClassify();/** 初始化一级展示分类 **/
});
编辑调用：
$(function () {
goodsClassifyAndSearchTag.getClassifyAndSearchTag("需要的参数");/** 回显展示类目以及搜索标签 **/
});
获取选中的返回值：
goodsClassifyAndSearchTag.returnSelectedClassifyAndTag()
