When working with Selenium for web automation, you might encounter a scenario where you need to delete specific characters from a textbox. For instance, you may need to delete the last two characters from a string like “ABCD” to get “AB”. This article provides a clear and practical guide to achieve this using Selenium.
Approach 1: Using ASCII Code
If you are using Java, you can delete a character from a textbox by sending the ASCII backspace character. Here’s how you can do it:
element.sendKeys("\\u0008");
This approach is straightforward and relies on using the Unicode representation of the backspace character.
Approach 2: Using Selenium Keys
While the ASCII method is valid, using predefined constants in Selenium can make your code more readable and maintainable. The Selenium library provides a Keys
class that includes a constant for the backspace key. Here’s how you can use it:
element.sendKeys(Keys.BACK_SPACE);
This method enhances code readability and aligns with standard practices in Selenium-based automation.
Practical Example
Let’s consider a practical example where we need to delete the last two characters from a textbox:
WebElement element = driver.findElement(By.id("textboxId"));
element.sendKeys(Keys.BACK_SPACE);
element.sendKeys(Keys.BACK_SPACE);
In this example, we locate the textbox using its ID and then send two backspace keys to delete the last two characters.
Conclusion
Both approaches are effective for deleting characters from a textbox using Selenium. The choice between them depends on your preference for code readability and maintainability. Using predefined constants from the Keys
class is generally recommended for clarity.
