Use:

driver.manage().timeOuts().implicitlyWait(10, TimeUnit.SECONDS);

这意味着对网页上元素的任何搜索都需要时间来加载。implicitlyWait在抛出异常之前设置。 TimeUnit显示您想要等待的任何方式(秒、分、小时和天)。

如果有人使用硒化物:

public static final Long SHORT_WAIT = 5000L; // 5 seconds
$("some_css_selector").waitUntil(Condition.appear, SHORT_WAIT);

在脚本中调用下面的函数，这将等待页面未使用javascript加载

public static boolean isloadComplete(WebDriver driver)
{
    return ((JavascriptExecutor) driver).executeScript("return document.readyState").equals("loaded")
            || ((JavascriptExecutor) driver).executeScript("return document.readyState").equals("complete");
}

SeleniumWaiter:

import com.google.common.base.Function;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.ui.WebDriverWait;

public class SeleniumWaiter {

      private WebDriver driver;

      public SeleniumWaiter(WebDriver driver) {
           this.driver = driver;
      }

      public WebElement waitForMe(By locatorname, int timeout){
           WebDriverWait wait = new WebDriverWait(driver, timeout);
           return wait.until(SeleniumWaiter.presenceOfElementLocated(locatorname));
      }

      public static Function<WebDriver, WebElement> presenceOfElementLocated(final By locator) {
            // TODO Auto-generated method stub
            return new Function<WebDriver, WebElement>() {
                 @Override
                 public WebElement apply(WebDriver driver) {
                      return driver.findElement(locator);
                 }
            };
      }
 }

对你来说:

_waiter = new SeleniumWaiter(_driver);

try {
   _waiter.waitForMe(By.xpath("//..."), 10);
} 
catch (Exception e) {
   // Error
}

Imran对Java 7的回答是:

    WebDriverWait wait = new WebDriverWait(driver, 30);

    wait.until(new ExpectedCondition<Boolean>() {
        public Boolean apply(WebDriver wdriver) {
            return ((JavascriptExecutor) driver).executeScript(
                "return document.readyState"
            ).equals("complete");
        }
    });

在我的例子中，我使用以下方法来了解页面加载状态。在我们的应用程序加载gif(s)是存在的，我听他们如下，以消除不必要的等待时间在脚本。

public static void processing(){ 
    WebDriverWait wait = new WebDriverWait(driver, 30);
    wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//div[@id='Msgpanel']/div/div/img")));
    wait.until(ExpectedConditions.invisibilityOfElementLocated(By.xpath("//div[@id='Msgpanel']/div/div/img")));
}

xpath在HTML DOM中定位gif的位置。 在此之后，您还可以实现您的动作方法单击。

public static void click(WebElement elementToBeClicked){
    WebDriverWait wait = new WebDriverWait(driver, 45);
    wait.until(ExpectedConditions.visibilityOf(element));
    wait.until(ExpectedConditions.elementToBeClickable(element)); 
    wait.ignoring(NoSuchElementException.class).ignoring(StaleElementReferenceException.class); elementToBeClicked.click(); 
 }
