问题 I have a list of elements obtained through the contains selector. Let's say I want to know how to access a person's name on a profile page. I can test my own profile with my own name. let name = $(':contains(jamie)'); I'd like to store a selector based on the above results that could be used to retrieve the name from any profile. Without walking the DOM and calculating a selector, is there another way to get a (single or list) selector to each element that comes out of the contains query? 回答1

问题 I have a few html files on my harddrive that I'd like to use jquery on to extract data from. Is this possible to do using cheerio? I've tried giving cheerio the local path but it doesn't work.

问题 I've written a script in node using two different functions getPosts() and getContent() supplying callback within them in order to print the result calling a standalone function getResult() .

How can I make it a go? I've written so far: var request = require('request'); var cheerio = require(

问题 I'm scraping an HTML page but I'm trying to get one section of the page.

The code looks like this. <b> Here's some text I don't want</b> <b> More text I don't want</b> <hr style="width:90%; padding: 0> <b> text I want </b> <b> text I want </b> <b> text I want </b> <b> text I want </b> <hr style="width:90%; padding: 0> <b> Here's some text I don't want

问题 Image of current source: Here Current code: let imageArr = [] $('.plink image').each(function(){ let image = $(this).attr('src') imageArr.push(image) }) console.log(imageArr) Log nothing , why so? 回答1: Don't has tag image , it is img . Use .plink.image img instead of .plink image . const $ = cheerio.load(body, { xmlMode: true // to load noscript }) let imageArr = [] $('.plink.image img').each(function(a, b) { let image = $(this).attr('src') if (image && !image.match(/white.jpg$/)) { // remove
