How to Execute JavaScript in C# with Selenium WebDriver?

Leveraging JavaScript with Selenium WebDriver in C#

Selenium WebDriver's ability to execute JavaScript offers powerful control over webpage elements, enabling sophisticated automation. This guide focuses on implementing JavaScript execution within C# using Selenium WebDriver.

Java vs. C# — A Syntax Comparison

Both Java and C# provide similar JavaScript execution capabilities within WebDriver, but their syntax differs. Java utilizes the JavascriptExecutor interface:

<code class="language-java">WebDriver driver; // Initialized elsewhere
JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("return document.title");</code>

C# Implementation

C#'s approach involves the IJavaScriptExecutor interface:

<code class="language-csharp">IWebDriver driver; // Assume initialization elsewhere
IJavaScriptExecutor js = (IJavaScriptExecutor)driver;
string title = (string)js.ExecuteScript("return document.title");</code>

The ExecuteScript method accepts a string containing the JavaScript code for execution.

Summary

Integrating JavaScript execution with Selenium WebDriver provides a robust solution for automation. Understanding the nuanced syntax variations between Java and C# is key to effectively utilizing this technique in your automation projects.
