css selectors - How to click on a link that has a certain content in puppeteer?

Question

If I have some content in my page such as:

<a>Hi!</a>

How can I use Google's Puppeteer to automate the clicking of that element?

I need to be able to select it based on its contents alone, not id, class or attribute.

Is there something like $('a:contains("Hi!")') that I can leverage to select this element?

How can I do this with https://github.com/GoogleChrome/puppeteer

thanks

Answer 1

Alternative approach using XPath

There is a much easier way to do it using an XPath expression:

const aElementsWithHi = await page.$x("//a[contains(., 'Hi!')]");
await aElementsWithHi[0].click();

Using page.$x, this code finds all a elements with the text Hi! inside. The result will be an array containing the matching a element handles. Using the elementHandle.click function, we can then click on the element.
