Introduction
In this blog, we will discuss the Javascriptexecutor in Selenium.
Web browser automation testing is also done using Selenium. However, Selenium WebDriver also often has issues with a few web components. For example, when a user opens a URL, an unusual pop-up may appear that prevents the WebDriver from finding a specific element and results in biased results. JavaScriptExecutor enters the scene in this situation. In this blog, we will discuss the Javascriptexecutor in Selenium.

What is JavascriptExecutor in Selenium?
Simply put, JavascriptExecutor is a system that allows Selenium to run JavaScript. Consider JavascriptExecutor in Selenium as a means for the WebDriver to communicate with HTML components in the browser, making using it easier. JavascriptExecutor is necessary to use this method in Selenium because JavaScript is a computer language that deals with HTML on the web.

Components of JavascriptExecutor in Selenium
Two methods comprise the JavascriptExecutor, which handles all key JavaScript actions for Selenium.
- executeScript method – This method runs the test script within the limits of the chosen window or frame. The method’s script is run as an anonymous function.
- a WebElements for an HTML element.
- Long for a decimal.
- Long for a number that is not a decimal.
- a Boolean for a Boolean.
- a String in all other situations.
- executeAsyncScript method – The asynchronous JavaScript code is run on the active window or frame. The remaining page will continue to read while an asynchronous script is run, improving responsiveness and application performance.
How to start with JavascriptExecutor
- Import the package
- Create a reference
- Call the JavascriptExecutor methods

Why does Selenium use JavascriptExecutor?
Selenium WebDriver may often be unable to carry out specific tasks or interact with particular web elements independently. In that case, JavaScript is needed to ensure that particular activity is carried out correctly. Let’s look at an example to grasp its value better.
Imagine that a tester has built a test script to click a few buttons, but there seems to be a problem because the script keeps failing. The tester utilizes JavascriptExecutor to fix this.
Conclusion
So far, we have enhanced the Javascriptexecutor in Selenium. The need for Selenium Web testers is rising and will continue to do so rapidly. As per Business Wire, Selenium has grown to be the most well-liked of all web testing tools, with a massive 300% increase in job posts over the coming three years.
