How to click on element with text in Puppeteer

Question

Is there any method (didn\'t find in API) or solution to click on element with text?

For example I have html:

Answer 1

The current top answer by tokland only works on text nodes and not on nodes with other elements inside.

Short answer

This XPath expression will query a button which contains the text "Button text":

const [button] = await page.$x("//button[contains(., 'Button text')]");
if (button) {
    await button.click();
}

To also respect the

surrounding the buttons, use the following code:

const [button] = await page.$x("//div[@class='elements']/button[contains(., 'Button text')]");

Explanation

To explain why using the text node (text()) is wrong in some cases, let's look at an example:

    Start End
    Start Middle End

First, let's check the results when using contains(text(), 'Text'):

• //button[contains(text(), 'Start')] will return both two nodes (as expected)
• //button[contains(text(), 'End')] will only return one nodes (the first) as text() returns a list with two texts (Start and End), but contains will only check the first one
• //button[contains(text(), 'Middle')] will return no results as text() does not include the text of child nodes

Here are the XPath expressions for contains(., 'Text'), which works on the element itself including its child nodes:

• //button[contains(., 'Start')] will return both two buttons
• //button[contains(., 'End')] will again return both two buttons
• //button[contains(., 'Middle')] will return one (the last button)

So in most cases, it makes more sense to use the . instead of text() in an XPath expression.
