如何在木偶操纵者的div中获取文本

const puppeteer = require("puppeteer");

(async function main() {
    try {
        const browser = await puppeteer.launch({headless: false});
        const page = await browser.newPage();
        page.setUserAgent("Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/72.0.3626.121 Safari/537.36");

        await page.goto("https://www.qimai.cn/rank/index/brand/all/genre/6014/device/iphone/country/us/date/2019-03-19", {waitUntil: 'load', timeout: 0});
        await page.waitForSelector(".container");
        const sections = await page.$$(".container");

        const freeButton = await page.$('[href="/rank/index/brand/free/device/iphone/country/us/genre/6014/date/2019-03-19"]');
        await freeButton.click();


        // free list

        const appTable = await page.waitForSelector(".data-table");
        const lis = await page.$$(".data-table > tbody > tr > td");

        // go to app content
        const appInfo = await page.$("a.icon");
        // appInfo.click();

        for (const content of lis) {
            const name = await content.$("div.appname");
            const gameName = await page.evaluate(name => name.innerText, name);
            console.log("Game Name: ", gameName);
        }

        console.log("-- bingo --");

    } catch (e) {
        console.log("our error", e);
    }
})();

我似乎无法从获取文本，我收到以下错误：
TypeError：无法读取Null的属性‘innerHTML’。我试了所有的方法，但都不管用。

推荐答案

我使用”waitForSelector”方法，然后尝试获取文本

await page.waitForSelector('your selector')
let element = await page.$('your selector')
let value = await page.evaluate(el => el.textContent, element)
