How do I interact with a hidden input field in Playwright?


Interacting with Hidden Input Fields in Playwright

You might find that you can't fill a hidden input field in Playwright using the 'force' option. This is because hidden elements are typically not accessible for interaction. But don't worry, there's a workaround.

Making Hidden Elements Visible

You can make the hidden input field visible by modifying its CSS properties. Here's how you can do it:

// Assuming 'page' represents your Playwright page object
await page.evaluate(() => {
  const hiddenInput = document.querySelector('#hidden-input');
  if (hiddenInput) {
    // Modify CSS properties to make the element visible
    hiddenInput.style.display = 'block';
    // Now you can fill its value
    hiddenInput.value = 'Your value';

In this code, we're using the page.evaluate() method to execute JavaScript code within the browser context. This gives us access to DOM manipulation capabilities. We select the hidden input field using document.querySelector(), change its CSS display property to make it visible, and then fill its value.

A Word of Caution

Remember, changing the visibility of hidden elements can affect the functionality or design of the web page you're automating. Make sure your automation actions align with the intended behavior of the website.

So, while you can't directly fill a hidden input field using the 'force' option in Playwright, you can make the element visible using JavaScript code executed through Playwright's API before performing any actions on it. Happy testing!
