无法定位元素：{"method":"xpath","selector":"//*[@id='identify_email']"}

Question

我收到以下错误：

Unable to locate element: 
{"method":"xpath","selector":"//*[@id='identify_email']"}

即使我写的选择器是正确的。我已经使用控制台检查了它。知道如何解决这个问题吗？

package lbw;


import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;

import org.openqa.selenium.chrome.ChromeDriver;

public class Locators {
public static void main(String[] args) {
    // TODO Auto-generated method stub

    System.setProperty("webdriver.chrome.driver",
    "C:\\Users\\vicky\\Documents\\chromedriver.exe");
    WebDriver driver=new ChromeDriver();
    driver.get("https://www.facebook.com");
    driver.findElement(By.id("email")).sendKeys("xxxxxxx@gmail.com");
    driver.findElement(By.name("pass")).sendKeys("xxxxxxxxxxx");
    driver.findElement(By.linkText("Forgotten account?")).click();
    driver.findElement(By.xpath("//*[@id=\'identify_email\']")).sendKeys("xxxxxxx@gmail.com");
    driver.findElement(By.xpath("//*[@value='Search']")).click();
    driver.findElement(By.cssSelector("input[id='send_email']")).click(); /*im getting error in this line. Im try to select a radio. */
    System.out.println("Completed");
}

}

您可以尝试添加 implicity wait 或 WebDriver wait。这是第二个例子：

public static void waitForElementPresent(this IWebElement element)
        {
            try
            {
                wait.Until(driver => element.Displayed);
            }
            catch (Exception e)
            {
                Assert.Fail("The element not found. The exception: \n" + e.GetType());
            }
        }
