readFile.ReadFile.Selector后无法提取链接文本。选择器在 Chrome 控制台中工作

Question

我正试图提取超链接文本。在google chrome控制台中，如果我把我的选择器放进去，我得到了想要的结果，--一个15个链接文本的列表。

当我用同样的选择器运行我的代码时，el.text在console.log中是未定义的，但索引却被记录在console.log中。

在最后，整个html被记录到控制台。

我是一个新手。

const request = require('request-promise');
const cheerio = require('cheerio');

const fs = require('fs');
const { JSDOM } = require("jsdom");
const { window } = new JSDOM("");
const filePath = './data/hb2019.html';

fs.readFile('./data/hb2019.html', 'utf8', (err, data) => {

    if (err) {
        console.log(err);
        return;
    }

    var $ = cheerio.load(data);

    $('#tableComparableSales tbody .salesReportSortLink').each(function (index, el) {
        console.log(el.text);
        console.log(index);
    });

    //console.log($.html());

});

Answer 1

应该是console.log(el.textContent)。

notconsole.log(el.text);
