[英]Get the last div element using cheerio
Hello I am implementing a scraper which scrape the latest message received in a telegram public channel.您好,我正在实施一个刮板,它刮取电报公共频道中收到的最新消息。 This is how the html is
这就是 html 的样子
I can fetch all the divs under section class tgme_channel_history
.我可以获取 class
tgme_channel_history
部分下的所有 div。 It has five divs under it which means five different messages.它下面有五个 div,这意味着五个不同的消息。 I want to get only the last div.
我只想得到最后一个 div。 How can I do that.
我怎样才能做到这一点。 You can check the live HTML here https://telegram.me/s/newlink01/
您可以在此处查看实时 HTML https://telegram.me/s/newlink01/
const $ = require('cheerio');
const url = 'https://telegram.me/s/newlink01/';
rp(url)
.then(function (html) {
//success!
const wikiUrls = [];
$('.tgme_channel_history', html).each(function () {
wikiUrls.push($(this).text()
});
console.log(wikiUrls[0]);
})
.catch(function (err) {
//handle error
});
You can pass a selector to jQuery.children()
to select all child div
elements, and then call jQuery.last()
to fetch the final one in the set.您可以将选择器传递给
jQuery.children()
到 select 所有子div
元素,然后调用jQuery.last()
以获取集合中的最后一个。
$(".tgme_channel_history").children("div").last();
