Is there a way to interact with pseudo HTML elements using Selenium WebDriver? For instance, elements like input::after and input::before that don't appear directly in the DOM but are visible on the page.
Is there a way to interact with pseudo HTML elements using Selenium WebDriver? For instance, elements like input::after and input::before that don't appear directly in the DOM but are visible on the page.
Imagine we have the following HTML setup (taken from a tutorial on example.com):
<!DOCTYPE html>
<html>
<head>
<style>
p::before {
content: "Check this out -";}
</style>
</head>
<body contenteditable="false">
<p>My name is Jane</p>
<p>I live in Janesville</p>
<p><b>Note:</b> In order for this selector to function in older browsers, like IE8, a DOCTYPE must be specified, and the old CSS2 syntax must be used (:before instead of ::before).</p>
</body>
</html>
In order to retrieve the content of the :before pseudo-element, you could utilize the following snippet of JavaScript embedded in your Selenium script:
Python
driver.execute_script("return window.getComputedStyle(document.querySelector('p'), ':before').getPropertyValue('content');")
Java
JavascriptExecutor jse = (JavascriptExecutor)driver;
jse.executeScript("return window.getComputedStyle(document.querySelector('p'), ':before').getPropertyValue('content');");
Expected output: "Check this out -"
