我不是发现在下拉框中clcking后yelp.com 选择“餐馆”能够点击“餐厅”，因为xpath无法定位元素。

我用selenium-webdriver，junit检查过。下面的代码对我来说工作得很好。检查这解决了你。

@Before 
    public void setUp() throws Exception { 
    driver = new FirefoxDriver(); 
    driver.manage().window().maximize(); 
    baseUrl = "http://www.yelp.com/"; 
    driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS); 
    } 

    @Test 
    public void testYelpRest() throws Exception { 
    driver.get(baseUrl + ""); 
    driver.findElement(By.id("find_desc")).clear(); 
    driver.findElement(By.id("find_desc")).sendKeys("Restaurants"); 
    driver.findElement(By.id("find_desc")).sendKeys(Keys.DOWN); 
    driver.findElement(By.id("find_desc")).sendKeys(Keys.ENTER); 
    for (int second = 0;; second++) { 
     if (second >= 60) fail("timeout"); 
     try { if (isElementPresent(By.xpath("//span[@class='pagination-results-window']"))) break; } catch (Exception e) {} 
     Thread.sleep(1000); 
    } 
    } 

    @After 
    public void tearDown() throws Exception { 
    driver.quit(); 
    String verificationErrorString = verificationErrors.toString(); 
    if (!"".equals(verificationErrorString)) { 
     fail(verificationErrorString); 
    } 
    }

你可以试试下面的代码，我敢肯定，这将工作.. :)

 public class Yelp_dropdown { 

    public static void main(String[] args) { 

     WebDriver driver=new FirefoxDriver(); 

     driver.get("http://www.yelp.com/"); 

     WebDriverWait w= new WebDriverWait(driver,5); 

     driver.findElement(By.xpath(".//*[@id='find_desc']")).click(); 

     w.until(ExpectedConditions.elementToBeClickable(By.xpath(".//*[@class='suggestion-detail suggestion-name' and contains (text(), 'Restaurants')]"))).click();
