} 贴出其中一个js实例例如提取用户所收藏物品。这里不是用直接翻页使用的是ajax以提升效率ajax一定需要同步方式。由于此接口是返回的页面不是json可以用css选择器。 1 /**2 * Created by ㄟ(▔▔)ㄏ on 2018/1/5.3 */4 /*5 * https://shoucang.taobao.com/nodejs/item_collect_chunk.htm?ifAllTag0tab0tagIdcategoryCount0type0tagNamecategoryNameneedNavfalsestartRow06 * 提取收藏的宝贝7 * */8 function myajax(opt) {9 opt opt || {};
