如何在RoboBrowser中启用JavaScript？表单提交问题求助

Unfortunately, the short answer is no—you can't enable JavaScript in RoboBrowser, and here's why:

RoboBrowser is built using requests (for handling raw HTTP requests) and BeautifulSoup (for parsing static HTML). It doesn't include a JavaScript engine at all, so it can't execute or render any JS-driven content. That's exactly why you're seeing that French "JavaScript must be enabled" page—the server detects your client doesn't support JS and serves the fallback version instead.

So what are your options? #

You've got two reliable ways to get past this and submit that form:

1. Use a real browser automation tool #

Tools like Selenium or Playwright control actual web browsers (Chrome, Firefox, Edge, etc.) that fully support JavaScript. They can load the page, run all the required JS, and let you interact with the form just like a human would.

Here's a quick example with Selenium in Python:

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

# Fire up Chrome
driver = webdriver.Chrome()
driver.get("your-survey-url-goes-here")

# Wait for the form to load (since JS might take a second to render it)
wait = WebDriverWait(driver, 10)
form = wait.until(EC.presence_of_element_located((By.ID, "your-form-id")))

# Fill in your form data
form.find_element(By.NAME, "field-name").send_keys("your-value")

# Submit the form
form.submit()

# Clean up when you're done
driver.quit()

2. Skip the browser entirely—call the API directly #

Lots of JS-heavy forms actually send their data to a backend API via a POST request. You can use your browser's DevTools to capture that request, then replicate it with requests (no browser needed).

Here's how to do it:

• Open the survey in your regular browser, hit F12 to open DevTools, and go to the Network tab.
• Fill out and submit the form normally. Look for a POST request in the network log (it'll probably be to something like /submit-survey or similar).
• Copy the request URL, headers, and form data (or JSON payload) from that request.
• Use requests.post() in Python to send the same request with your data.

This method is usually faster than using a browser tool, but it does require a bit of digging to figure out the exact API endpoint and payload structure.
