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

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.


First, we have to find element by text.

/**
 * findElemByText - Find an Element By Text
 *
 * @param  {String} str                case-insensitive string to search
 * @param  {String} selector = '*'     selector to search
 * @param  {String} leaf = 'outerHTML' leaf of the element
 * @return {Array}                     array of elements
 */
function findElemByText({str, selector = '*', leaf = 'outerHTML'}){
  // generate regex from string
  const regex = new RegExp(str, 'gmi');

  // search the element for specific word
  const matchOuterHTML = e => (regex.test(e[leaf]))

  // array of elements
  const elementArray = [...document.querySelectorAll(selector)];

  // return filtered element list
  return elementArray.filter(matchOuterHTML)
}

// usage
// findElemByText({str: 'Example', leaf: 'innerHTML', selector: 'title'});
// findElemByText({str: 'Example', selector: 'h1'});
// findElemByText({str: 'Example'});

Save it in same folder as your puppeteer script, name it script.js.

Now, we can use this in our puppeteer script. We can use ElementHandle, but for simplicity of understanding, I'll use .evaluate() function provided with puppeteer.

const puppeteer = require('puppeteer');

(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.goto('https://example.com');

  // expose the function
  await page.addScriptTag({path: 'script.js'});

  // Find Element by Text and Click it
  await page.evaluate(() => {
   // click the first element 
   return findElemByText({str: 'More'})[0].click();
  });

  // Wait for navigation, Take Screenshot, Do other stuff
  await page.screenshot({path: 'screenshot.png'});
  await browser.close();
})();

Do not copy paste the code above, try to understand it and type them yourself. If the code above fails, try to find why it's failing.
