使用selenium webdriver自动执行脚本时， .is dispayed（）命令在 if else语句中无效。 如果在if语句下条件为真，那么它工作正常。但如果条件不成立，则代码不会移动到else语句。

实际上isDisplayed()工作正常。问题在你的循环中。在first if条件中，您使用i+5增加了值，因此在下一次迭代中，值x在xpath中不匹配，这就是它在Exception中移动的原因。

您需要在try catch块中管理if else条件。替换下面的循环代码并尝试

int i=5;
while(i<=44)
{
    try
    {
        if(driver.findElement(By.xpath("//*[@id='dice_paging_top']//*[contains(text(),'"+i+"')]")).isDisplayed()  )
        {
            driver.findElement(By.xpath("//*[@id='dice_paging_top']//*[contains(text(),'"+i+"')]")).click();
            Thread.sleep(5000);
            i+=5;
        }

     }catch(Exception e)
       {
            try
            {
                 if(driver.findElement(By.xpath("//*[@id='dice_paging_top']//a[@title='Go to next page']")).isDisplayed() )
                 {
                     driver.findElement(By.xpath("//*[@id='dice_paging_top']//a[@title='Go to next page']")).click();
                 }
            }
            catch(Exception e2)
            {
                driver.quit();
           }
     }
}

在第二次迭代中，我将值设置为7，在xpath中使用此值，当前页面上不存在元素。如果页面上不存在该元素，则drive.findElement将抛出NoSuchElementException，因此它赢得了＃ 39;完全输入你的elseif块我相应地修改了你的代码（更新下面的解决方案，最后提供我的解决方案）。

import java.util.concurrent.TimeUnit;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;

public class Dice {
static WebDriver driver = null;
public static void main(String[] args) throws InterruptedException {
    System.setProperty("webdriver.chrome.driver", "D:\\Automation Software\\chromedriver_win32\\chromedriver_update.exe");
    driver = new ChromeDriver();
    driver.manage().window().maximize();
    driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
    //driver.manage().timeouts().pageLoadTimeout(20, TimeUnit.SECONDS);
    driver.get("http://www.dice.com/");
    Thread.sleep(15000);
    driver.findElement(By.xpath("//*[@alt='Close']")).click();
    driver.findElement(By.xpath("//*[@id='search-field-keyword']")).sendKeys("Selenium WebDriver");
    WebElement Place =driver.findElement(By.xpath("//input[@placeholder='Location']"));
    Place.clear();
    driver.findElement(By.xpath("//button[contains(text(),'Find Tech Jobs')]")).click();
    WebElement PageNumber = driver.findElement(By.xpath("//*[@id='dice_paging_top']//*[contains(text(),'2')]"));
    int i=2;
    while(i<=44)
    {
        try
        {
            if(driver.findElement(By.xpath("//*[@id='dice_paging_top']//*[contains(text(),'"+i+"')]")).isDisplayed()  )
            {
                driver.findElement(By.xpath("//*[@id='dice_paging_top']//*[contains(text(),'"+i+"')]")).click();
                Thread.sleep(5000);
                i+=1;
            }
        }  
        catch (Exception e)
        {
            try{
                if(driver.findElement(By.xpath("//*[@id='dice_paging_top']//a[@title='Go to next page']")).isDisplayed() )
                {
                    driver.findElement(By.xpath("//*[@id='dice_paging_top']//a[@title='Go to next page']")).click();
                    i+=1;
                }
            }
            catch(Exception e1){
                driver.quit();
            }
          }

       }   
      }   
    }

如果你的目标是通过所有工作岗位，那么下面是我的缩短代码。

import java.util.concurrent.TimeUnit;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;

public class Dice {
  static WebDriver driver = null;
public static void main(String[] args) throws InterruptedException {
    System.setProperty("webdriver.chrome.driver", "D:\\Automation Software\\chromedriver_win32\\chromedriver_update.exe");
    driver = new ChromeDriver();
    driver.manage().window().maximize();
    driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
    driver.get("http://www.dice.com/");
    Thread.sleep(15000);
    driver.findElement(By.xpath("//*[@alt='Close']")).click();
    driver.findElement(By.xpath("//*[@id='search-field-keyword']")).sendKeys("Selenium WebDriver");
    WebElement Place =driver.findElement(By.xpath("//input[@placeholder='Location']"));
    Place.clear();
    driver.findElement(By.xpath("//button[contains(text(),'Find Tech Jobs')]")).click();
    while(true)
    {
        List<WebElement> nextPage = driver.findElements(By.xpath("//*[@id='dice_paging_top']//a[@title='Go to next page']"));
        if(nextPage.size()>0&&nextPage.get(0).isEnabled()){
            nextPage.get(0).click();
        }
        else{
            break;
        }
    }
    driver.quit();
   }   
  }
