jquery,tree无限级树形菜单+简单实用案例

我在项目中用到产品类别的树形。各种地方都要用。 我就封装起来,方便以后调用。

记录下来,希望给新手们提供帮助。要记得导入jquery.js  tree.js 哦

Json 数据字符串
web.goodsCategoryJson =  [{"cateID":"05E19A7462A148709CE295CA2295BD7E","cateName":"计算机","parentCateID":"43242"},{"cateID":"43242","cateName":"电器","parentCateID":"1"},{"cateID":"43243","cateName":"服装1","parentCateID":"1"},{"cateID":"43244","cateName":"女装","parentCateID":"43243"},{"cateID":"43245","cateName":"根目录","parentCateID":"43243"},{"cateID":"43246","cateName":"根目录6","parentCateID":"43244"},{"cateID":"43247","cateName":"根目录7","parentCateID":"43245"},{"cateID":"43248","cateName":"根目录8","parentCateID":"43246"},{"cateID":"43249","cateName":"根目录9","parentCateID":"43247"},{"cateID":"43250","cateName":"根目录0","parentCateID":"43248"},{"cateID":"43251","cateName":"根目录1","parentCateID":"43249"},{"cateID":"43252","cateName":"根目录2","parentCateID":"43250"},{"cateID":"43253","cateName":"根目录3","parentCateID":"2"},{"cateID":"1","cateName":"通用分类","parentCateID":"-1"},{"cateID":"2","cateName":"频道分类","parentCateID":"-1"}]
