How to Click an Element Based on Text Content Using Puppeteer?

Clicking on an Element with Text Using Puppeteer

Challenge: Locating and clicking an element based solely on its text content.

Consider the following HTML snippet:

<code class="html"><div class="elements">
    <button>Button text</button>
    <a href="#">Href text</a>
    <div>Div text</div>
</div></code>

Copy after login

Objective: Implement a click action on the button element that contains "Button text."

Solution:

The XPath expression below identifies the button containing the desired text:

"//button[contains(., 'Button text')]"

Copy after login

However, to ensure compatibility with the surrounding

container, use this modified expression:

"//div[@class='elements']/button[contains(., 'Button text')]"

Copy after login

To execute the click action:

const [button] = await page.$x(&quot;//div[@class='elements']/button[contains(., 'Button text')]&quot;);
if (button) {
    await button.click();
}

Copy after login

Explanation:

Using .contains(., 'Text') instead of .contains(text(), 'Text') XPath expression ensures that it includes child nodes, thus not excluding text nodes deeper in the element structure.
