Question

我正在尝试使用Puppeteer访问可点击的输入广播以推进我的应用程序调查。下面是选择器和xpath标记。

选择器：

#survey-engine > span > div > div > div > div > div.col-xs-12.col-xl-offset-2.col-xl-8.col-lg-offset-1.col-lg-10 > div > div:nth-child(1) > input[type="radio"]

XPath：

//*[@id="survey-engine"]/span/div/div/div/div/div[2]/div/div[1]/input

我无法使xpath或选择器正常工作。我也试过使用下面但没有运气。使用选择器查看错误：

>UnhandledPromiseRejectionWarning: AssertionError [ERR_ASSERTION]: No node found for selector: #survey-engine > span > div > div > div > div > div.col-xs-12.col-xl-offset-2.col-xl-8.col-lg-offset-1.col-lg-10 > div > div:nth-child(1) > input[type="radio"]

(await page.$x("//input[contains(text(), 'My Input's Text')]"))[0];

有没有人有任何想法？

Answer 1

await page.evaluate(() => {
       var test = document.querySelector('#survey-engine > span > div > div > div > div > div.col-xs-12.col-xl-offset-2.col-xl-8.col-lg-offset-1.col-lg-10 > div > div:nth-child(1) > input[type="radio"]')
        test.click();
    })

Answer 2

你能不能简单地尝试（假设jquery在页面上）？

var input = await page.evaluate(() => {
  return $('#survey-engine > span > div > ... > div:nth-child(1) > input[type="radio"]';
});

注意为了简洁起见，我从您的问题中删除了一些选择器...
