Using Python and WebDriver to implement form automatic filling function

Use Python and WebDriver to implement automatic form filling function

In daily website browsing, we often encounter situations where we need to fill in forms. When we need to fill out the same or similar forms frequently, manual filling becomes tedious and time-consuming. Fortunately, we can use Python and WebDriver to realize the function of automatically filling in forms and improve our work efficiency.

First, we need to install the selenium library. Selenium is an automated testing tool that can simulate human browsing behavior and interact with various browsers. Through the WebDriver interface provided by Selenium, we can use Python to control the browser and implement automated operations.

First, we need to import the necessary libraries and modules:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

Next, we need to select a browser for automation. Here we choose Chrome browser. After downloading the corresponding version of the Chrome browser, we need to download the corresponding ChromeDriver driver. ChromeDriver allows us to control the Chrome browser through Python. Place the downloaded ChromeDriver executable file in the appropriate path and add the path to the system environment variable.

driver = webdriver.Chrome()

Now we can open the specified URL:

driver.get("https://www.example.com")

Next, we need to find the form element to be filled out. Elements can be located through their id, name, class and other attributes. Use the methods starting with find_element_by_ to choose different positioning methods. For example, use the find_element_by_id method to locate the element by its id.

element = driver.find_element_by_id("username")

Now we can start filling in the form automatically. You can use the send_keys method to enter the corresponding content:

element.send_keys("John Doe")

If you need to clear the content in the input box, you can use the clear method:

element.clear()

You can also use the submit method to submit the form:

element.submit()

Finally, we need to close the browser. You can use the quit method to close the current browser window, or you can use the close method to close the current tab.

driver.quit()

Taken together, we can write a Python script to automatically fill in the form:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Chrome()
driver.get("https://www.example.com")

element = driver.find_element_by_id("username")
element.send_keys("John Doe")

element = driver.find_element_by_id("password")
element.send_keys("pa55word")

element.submit()

driver.quit()

This is a simple example. In fact, we can use Python and WebDriver more flexibly to automatically fill in various forms. types of forms. By locating elements and using corresponding methods, we can implement operations such as input, clearing, and submission.

In short, using Python and WebDriver to implement the form automatic filling function can greatly improve our work efficiency. With the help of automated testing tools and technologies, we can hand over the tedious form filling process to machines, thus saving time and energy. Hope this article is helpful to you.
