To pass a variable from Python to Selenium JavaScript, you can use the execute_script method provided by the WebDriver instance. This method allows you to execute custom JavaScript code within the context of the current web page. You can pass Python variables as arguments to the JavaScript code.
Here's an example using Python:
Install the required package:
pip install selenium
Create a method to execute JavaScript with a Python variable:
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
def execute_javascript_with_python_variable(driver, locator, python_variable):
element = WebDriverWait(driver, 10).until(EC.visibility_of_element_located(locator))
return driver.execute_script("return arguments[0] + arguments[1];", element.text + python_variable)
Use the execute_javascript_with_python_variable method in your test code:
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
# Set up the WebDriver
driver = webdriver.Chrome()
driver.maximize_window()
# Navigate to the target web page
driver.get("https://www.example.com")
# Locate the element you want to interact with
locator = (By.ID, "element-id")
# Execute JavaScript with a Python variable
result = execute_javascript_with_python_variable(driver, locator, "Hello, World!")
# Print the result
print(result)
# Perform any additional actions as needed
# Close the browser
driver.quit()
In this example, we first create a method called execute_javascript_with_python_variable that takes a driver instance, a locator tuple containing the locator strategy and locator value, and a python_variable string containing the Python variable value. Inside the method, we use the WebDriverWait class to wait for the element to become visible and then call the execute_script method with the JavaScript code that concatenates the element's text and the Python variable.
In the test code, we set up the WebDriver, navigate to the target web page, and locate the element using the locator variable. We then call the execute_javascript_with_python_variable method with the driver, locator, and "Hello, World!" as input. The method returns the concatenated result, which we print in the console.
Remember to replace "https://www.example.com", "element-id", and "Hello, World!" with the actual URL, element ID or locator, and desired Python variable value.
