If you’re involved in web development or testing, you’ve likely come across the powerful Selenium WebDriver tool. Selenium WebDriver provides a comprehensive set of methods and commands to interact with web elements effectively. In this article, we will explore the key Selenium WebElement methods and commands, such as clear(), sendKeys(), click(), isDisplayed(), isEnabled(), isSelected(), submit(), getText(), getTagName(), getCssValue(), getAttribute(), getSize(), and getLocation(). Let’s dive in and discover how these methods can enhance your web automation capabilities!

1. WebElement: The Foundation of Web Interaction
Before we delve into the various WebElement methods, let’s understand what a WebElement is. In Selenium WebDriver, a WebElement represents an individual web element on a webpage, such as a button, input field, link, or dropdown. It acts as a handle to manipulate and interact with these elements programmatically.
2. clear(): Clearing Input Fields
The clear() method is used to clear the content of an input field. It ensures that the field is empty before entering new text or performing any other action. Here’s an example that demonstrates the usage of clear():
WebElement usernameField = driver.findElement(By.id("username"));
usernameField.clear();
3. sendKeys(): Entering Text
The sendKeys() method allows you to simulate user typing by entering text into input fields. You can provide the desired text as an argument to this method. Here’s an example:
WebElement searchField = driver.findElement(By.id("search"));
searchField.sendKeys("Selenium WebDriver");
4. click(): Clicking on Elements
The click() method is used to simulate a mouse click on a web element. It is commonly used to interact with buttons, links, checkboxes, and radio buttons. Here’s an example:
WebElement submitButton = driver.findElement(By.id("submit"));
submitButton.click();
5. isDisplayed(): Checking Element Visibility
The isDisplayed() method allows you to check whether an element is currently visible on the webpage or not. It returns a boolean value (true or false) based on the visibility status of the element. Here’s an example:
WebElement logoImage = driver.findElement(By.className("logo"));
boolean isVisible = logoImage.isDisplayed();
6. isEnabled(): Verifying Element State
The isEnabled() method helps you determine whether an element is in an enabled state or not. It is commonly used to validate whether a button, input field, or any other interactive element can receive user input. Here’s an example:
WebElement submitButton = driver.findElement(By.id("submit"));
boolean isEnabled = submitButton.isEnabled();
7. isSelected(): Checking Element Selection
The isSelected() method is primarily used for checkbox and radio button elements. It allows you to check whether a checkbox or radio button is selected or not. Here’s an example:
WebElement checkBox = driver.findElement(By.id("newsletter"));
boolean isSelected = checkBox.isSelected();
8. submit(): Submitting Forms
The submit() method is used to submit HTML forms. When invoked on a form element, it triggers the form submission process. Here’s an example:
WebElement form = driver.findElement(By.tagName("form"));
form.submit();
9. getText(): Retrieving Text from Elements
The getText() method allows you to extract the visible text content from an element. It is commonly used to retrieve text from headings, paragraphs, labels, and other elements. Here’s an example:
WebElement heading = driver.findElement(By.tagName("h1"));
String headingText = heading.getText();
10. getTagName(): Getting Element Tag Name
The getTagName() method returns the HTML tag name of an element. It provides information about the type of element being inspected. Here’s an example:
WebElement button = driver.findElement(By.tagName("button"));
String tagName = button.getTagName();
11. getCssValue(): Fetching CSS Values
The getCssValue() method allows you to retrieve the value of a specific CSS property applied to an element. It can be used to extract style-related information, such as color, font size, or background color. Here’s an example:
WebElement heading = driver.findElement(By.tagName("h1"));
String colorValue = heading.getCssValue("color");
12. getAttribute(): Obtaining Element Attributes
The getAttribute() method allows you to fetch the value of a specified attribute of an element. It is commonly used to retrieve attributes like “id,” “class,” “href,” or any other custom attributes associated with the element. Here’s an example:
WebElement link = driver.findElement(By.tagName("a"));
String hrefValue = link.getAttribute("href");
13. getSize(): Getting Element Size
The getSize() method returns the width and height of an element as a Dimension object. It provides information about the size of an element, which can be useful for layout verification or interacting with elements based on their size. Here’s an example:
WebElement element = driver.findElement(By.id("elementId"));
Dimension size = element.getSize();
int width = size.getWidth();
int height = size.getHeight();
14. getLocation(): Retrieving Element Location
The getLocation() method retrieves the coordinates of the upper-left corner of an element relative to the webpage’s top-left corner. It helps you determine the position of an element, which can be useful for interacting with elements based on their location. Here’s an example:
WebElement element = driver.findElement(By.id("elementId"));
Point location = element.getLocation();
int x = location.getX();
int y = location.getY();
Conclusion
In this article, we explored the powerful Selenium WebElement methods that enable you to interact with web elements seamlessly. We covered essential methods such as clear(), sendKeys(), click(), isDisplayed(), isEnabled(), isSelected(), submit(), getText(), getTagName(), getCssValue(), getAttribute(), getSize(), and getLocation(). By utilizing these methods effectively, you can automate web interactions, perform validations, and enhance your web testing capabilities.

Please note that you need to replace "path/to/chromedriver" with the actual path to the ChromeDriver executable file on your system. Also, ensure that you have the appropriate Selenium WebDriver libraries added to your project.
This code sets up the WebDriver, initializes the Chrome browser, and provides separate methods for each WebElement method example. The main method demonstrates how you can call these methods to perform various actions on web elements using Selenium WebDriver.
In case you are using webdriver manager, then replace below code with Selenium WebDriver Manager code as mentioned in this.
System.setProperty("webdriver.chrome.driver", "path/to/chromedriver");
driver = new ChromeDriver();
