在Selenium WebDriver中执行javascript

  在Selenium WebDriver中执行javascript的方法很简单：

public class JavaScriptExample {
    public static void main(String[] args) {

        System.setProperty("webdriver.chrome.driver", "C:\\Dagger-master\\res\\chromedriver.exe");

        ChromeOptions options = new ChromeOptions();
        options.addArguments("window-size=1024,768");

        DesiredCapabilities capabilities = DesiredCapabilities.chrome();
        capabilities.setCapability(ChromeOptions.CAPABILITY, options);
        WebDriver driver = new ChromeDriver(capabilities);

        driver.get("http://google.com/");

        if (driver instanceof JavascriptExecutor) {
            ((JavascriptExecutor) driver).executeScript("alert('hello world');");
        }


    }
