一、为什么要让元素高亮显示?

为了更准确的显示查找到的元素,可以让元素高亮显示。

 

二、如何实现?

public class TestGaoLiang {
	public static void main(String[] args) throws InterruptedException {
		System.setProperty("webdriver.chrome.driver",
				"C:\\Program Files (x86)\\Google\\Chrome\\Application\\chromedriver.exe");
		WebDriver driver = new ChromeDriver();
		driver.manage().window().maximize();
		driver.manage().timeouts().pageLoadTimeout(10, TimeUnit.SECONDS);
		driver.get("http://www.baidu.com");
		WebElement oEdit = driver.findElement(By.name("wd"));
		highlightElement(driver, oEdit);
		WebElement oButton = driver.findElement(By.id("su"));
		highlightElement(driver, oButton);
		driver.quit();
	}

	public static void highlightElement(WebDriver driver, WebElement element) throws InterruptedException {

		JavascriptExecutor js = (JavascriptExecutor) driver;
		js.executeScript("element = arguments[0];" + "original_style = element.getAttribute('style');"
				+ "element.setAttribute('style', original_style + \";"
				// 背景色为黄色;红色加粗边框显示。
				+ "background: yellow; border: 2px solid red;\");"
				// 高亮显示3s
				+ "setTimeout(function(){element.setAttribute('style', original_style);}, 10000);", element);
		Thread.sleep(10000);
	}
}
