问题描述

我想知道我是否可以告诉木偶操作员等到显示的元素。

I would like to know if I can tell puppeteer to wait until an element in displayed.

const inputValidate = await page.$('input[value=validate]');
await inputValidate.click()

//I want to do something like that
waitElemenentVisble('.btnNext ')

const btnNext = await page.$('.btnNext');
await btnNext.click();

我有什么方法可以做到这一点吗?

Is there any way I can accomplish this?

推荐答案

我认为您可以为此目的使用 page.waitForSelector(selector [,options])函数。

I think you can use page.waitForSelector(selector[, options]) function for that purpose.

const puppeteer = require('puppeteer');

puppeteer.launch().then(async browser => {
  const page = await browser.newPage();
  page
    .waitForSelector('#myId')
    .then(() => console.log('got it');
  browser.close();
});
