}

如果你想等待一个特定的元素加载，你可以在RenderedWebElement上使用isdisplay()方法:

// Sleep until the div we want is visible or 5 seconds is over
long end = System.currentTimeMillis() + 5000;
while (System.currentTimeMillis() < end) {
    // Browsers which render content (such as Firefox and IE) return "RenderedWebElements"
    RenderedWebElement resultsDiv = (RenderedWebElement) driver.findElement(By.className("gac_m"));

    // If results have been returned, the results are displayed in a drop down.
    if (resultsDiv.isDisplayed()) {
      break;
    }
}

(例子来自《5分钟入门指南》)

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(); 
 }

对于存在的任何元素使用if条件和

try {
    Thread.sleep(1000);
} catch (InterruptedException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

这段代码将等待页面上的所有元素都加载到DOM中。

WebDriver driver = new WebDriver();
WebDriverWait wait = new WebDriverWait(driver, timeout);

wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//*")));

你可以使用下面的代码片段来加载页面:

    IWait wait = new OpenQA.Selenium.Support.UI.WebDriverWait(driver,TimeSpan.FromSeconds(30.00));
    wait.Until(driver1 => ((IJavaScriptExecutor)driver).ExecuteScript("return document.readyState").Equals("complete"));

或者你可以使用waiter的任何元素被加载，并成为可见/可点击的页面上，最有可能的是，这将是在加载结束时加载，如:

    Wait.Until(ExpectedConditions.ElementToBeClickable(By.XPath(xpathOfElement));
    var element = GlobalDriver.FindElement(By.XPath(xpathOfElement));
    var isSucceededed = element != null;
