Can I set any of the attribute value of a WebElement in Selenium?
We can set any attribute value of a webelement in Selenium. Selenium can run Javascript commands by the executeScript method. The command to be executed is passed as an argument to the method.
Next, we have to identify the element with the help of the Javascript method document.getElementsByClassname. It returns a list of elements, to point to the first element we shall add index [0]. To set the attribute we shall use the setAttribute method.
Syntax for setting the style attribute −
JavascriptExecutor j = (JavascriptExecutor) driver;
js.executeScript
("document.getElementsByClassName('heading')[0].setAttribute('style', 'background-color: red')");Let us set the background color of webelement to red.
Example
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.JavascriptExecutor;
public class SetAttributeVal{
public static void main(String[] args) {
System.setProperty("webdriver.chrome.driver",
"C:\Users\ghs6kor\Desktop\Java\chromedriver.exe");
WebDriver driver = new ChromeDriver();
driver.get("https://www.tutorialspoint.com/index.htm");
// Javascript executor to set background color to red
JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript
js.executeScript
("document.getElementsByClassName('heading')[0].setAttribute('style', 'background-color: red')");
driver.quit();
}
}Output
