筛选数据

@H_301_0@以网页中的综艺热点部分

@H_301_0@相关源代码如下

@H_301_0@　　通过分析可知，‘综艺'模块与其他模块都位于

名称位于 @H_301_0@cheerio

@H_301_0@我们怎么从源代码中获取到有用的数据呢？首先，nodeJS不支持document对象。如果要使用笨办法，只能使用正则表达式来处理

@H_301_0@cheerio 是nodejs特别为服务端定制的，能够快速灵活的对JQuery核心进行实现。它工作于DOM模型上，且解析、操作、呈送都很高效

@H_301_0@

【安装】

@H_193_403@

@H_301_0@【使用】

@H_301_0@它的使用方法和jQuery相当类似，上手非常容易。以获取综艺热度前10名的节目名称为例

搜索量前10的综艺节目标题 var result = []; //将页面源代码转换为$对象 var $ = cheerio.load(data); //查找每个综艺节目标题的外层div var temp_arr = $('[monkey = "zy"]').find('.point-bd').find('.point-title'); //将综艺节目标题依次保存到结果数组中 temp_arr.each(function(index,item){ result.push($(item).text()); }) //[ '变形计','来吧冠军','拜托了冰箱','昆仑决','天生是优我','姐姐好饿','脑力男人时代','奔跑吧兄弟','我想和你唱','玫瑰之旅' ] console.log(result); }

爬虫代码

@H_301_0@下面将hao123网页中的'实时热点'、'今日热点'、'民生热点'、'电影'、'电视剧'、'综艺'这6部分的排名爬下来，分别到对象名为'result'中的数组中，分别命令为'ss'、'jr'、'ms'、'dy'、'dsj'、'zy'

@H_301_0@【代码如下】

搜索量前10的名称 //对象名为榜单名，如'实时热点' //对象内容为10个标题名称组成的数组 var result = {}; //将页面源代码转换为$对象 var $ = cheerio.load(data); //查找'实时热点'、'今日热点'、'民生热点'、'电影'、'电视剧'、'综艺'这6个榜单所在的div var temp_div = $('.top-wrap');

//保存榜单名称
var temp_title = [];

temp_div.each(function(index,item){
//查找榜单名，并保存到temp_title文件夹中
temp_title.push($(item).find('h2').text());

//查找每类下每个标题的外层div
var temp_arr = $(item).find('.point-bd').find('.point-title');

//将result下的每个榜单初始化为一个数组
var innerResult = result[temp_title[index]] = [];

//将节目标题依次保存到相应榜单的数组中
temp_arr.each(function(_index,_item){
innerResult.push($(_item).text())
})
})
console.log(result);
}
