::before ::after怎么选取该标签？因为需要对其进行其他js得操作，需要选取，用.bars和class::before都选取不到
改过的
const puppeteer = require('puppeteer');
(async () => {
const browser = await puppeteer.launch({
headless: false,
timeout: 30000,
});
const page = await browser.newPage();
await page.goto('http://localhost:62114/Account/Login?ReturnUrl=%2F');
//await page.waitFor(500);
await page.click("a[data-target='#TenantChangeModal']")
await page.waitFor(1000);
//await page.waitForSelector("input[name='TenancyName']");
await page.type("input[name='TenancyName']",'Default',{delay:100})
await page.waitFor(500);
await page.click('.btn.btn-primary.save-button.waves-effect');
await page.waitFor(2000);
await page.type("input[name='usernameOrEmailAddress']",'admin',{delay:100});
await page.waitFor(500);
await page.type("input[name='Password']",'123qwe',{delay:100});
const navigationPromise = page.waitForNavigation();
await page.click('#LoginButton'); //然后点击
await page.waitFor(3000);
await page.click( css('.bars::after{content:\'test\';font-size:80px;}'));
//await page.click("a[class='bars::before']"); //然后点击
})();
var css=function(t,s){
s=document.createElement('style');
s.innerText=t;
document.body.appendChild(s);
};
