请尝试以下操作：
package PageObjects;import org.openqa.selenium.By;import org.openqa.selenium.WebDriver;import org.openqa.selenium.WebElement;import org.openqa.selenium.support.ui.ExpectedConditions;import org.openqa.selenium.support.ui.WebDriverWait;public class SignIn { private static WebElement element = null; public static WebElement SignIn_click(WebDriver driver) throws InterruptedException { element = driver.findElement(By.xpath("id('J_SC_header')/header/div[2]//span[1]/a[@data-val='ma_signin']")); while (!isDisplayed(element)) { Thread.sleep(3000); System.out.println("Element is not visible yet"); } return element; } public static boolean isDisplayed(WebElement element) { try { if(element.isDisplayed()) return element.isDisplayed(); }catch (NoSuchElementException ex) { return false; } return false; }}
