Discovering an element within a shadow root using Selenium in conjunction with Java

Is there a way to retrieve the "Solve the challenge" button from within the shadow-root (closed) element? Here is what I've attempted so far:

driver.findElement(By.xpath("//[@id=\"solver-button\"]")).click();

Unfortunately, the button cannot be accessed due to the presence of the shadow-root element. I need a solution to access the button with the id solver-button within the shadow root element.

Answer №1

The element titled Solve the challenge can be found within a #shadow-root (open)

Solution

In order to click() on the desired element, you can utilize shadowRoot.querySelector() along with the recommended Locator Strategy:

WebElement solverButton = (WebElement) js.executeScript("return document.querySelector('div.button-holder.help-button-holder').shadowRoot.querySelector('button#solver-button')");
solverButton.click();

Answer №2

If you find that clicking on the parent element (

<div class="button-holder help-button-holder"></div>
) of the shadow-root element is sufficient, you can refer to this helpful post.

To simulate a mouse click on the help-button-holder element, you can utilize the moveToElement method like this:

WebElement buttonHolderElement = driver.findElement(By.xpath("//*[@id=\"rc-imageselect\"]/div[3]/div[2]/div[1]/div[1]/div[4]"));
Actions actionProvider = new Actions(driver);
actionProvider.moveToElement(buttonHolderElement).click().build().perform();

For more information, you can refer to the detailed selenium documentation on mouse actions.

Answer №3

var button = driver.executeScript("return document.querySelector('div[class=\"button-container\"]').shadowRoot.querySelector('button[id=\"click-me-button\"]')");
button.click();

In the HTML Document Object Model (DOM), the shadowRoot is a separate entity that must be accessed before targeting elements within it. Remember to first locate the root element with the shadow root and then navigate to the desired element within it.
