登录后,页面重定向到一个页面(我想等待页面加载),我在那里通过tagName查找元素,
By inputArea = By.tagName("input");
List <WebElement> myIput = driver.findElements(inputArea);
在这里,我想给明确等待findElements,我想等待它的所有可见性或存在。我的网页只有两个输入。如果我给Implicit Wait很长时间,代码就可以了。但它有所不同。所以我决定给出显式等待,我怎样才能明确等待findElements?或者如何从列表中检查第二个的可见性(列出myIput)。即,myIput.get(1)。当我给下面的visibilityOfAllElements()时,它会抛出错误。
WebDriverWait waitForFormLabel = new WebDriverWait(driver, 30);
By inputArea = By.tagName("input");
List <WebElement> myIput = driver.findElements(inputArea);
waitForFormLabel.until(ExpectedConditions.visibilityOfAllElements(myIput));
myIput.get(1).sendKeys("Test");
这是我在自动化程序中使用的代码列表。

driver.findElement(By.xpath("//input[contains(@src,'/images/signin.png')]")).click();

List <WebElement> myIput = driver.findElements(inputArea);
waitForFormLabel.until(ExpectedConditions.visibilityOfAllElements(myIput));
myIput.get(1).sendKeys("Test");
}
}
请注意:如果我在代码“driver.navigate()。to(baseUrl +”/ anglr / form-builder / dist /#/ forms“);”之后给了Thread.sleep很长时间,“我将获得所有WebElements。但我想避免这种情况,我想等待WebElements加载()。
任何人请帮助。
你可以这样做:
//explicit wait for input field field
WebDriverWait wait = new WebDriverWait(driver, 10);
wait.until(ExpectedConditions.visibilityOfElementLocated(By.tagName("input")));
ExpectedConditions
类在很多情况下都很有用,并提供了一些等待元素的预定义条件。这里是其中的一些:
alertIsPresent
:警报存在elementSelectionStateToBe
:元素状态是选择。elementToBeClickable
:元素存在且可点击。elementToBeSelected
:元素被选中frameToBeAvailableAndSwitchToIt
:框架可用并选择框架。invisibilityOfElementLocated
:一个元素是不可见的presenceOfAllElementsLocatedBy
:现在的元素位于。textToBePresentInElement
:特定元素上的文本textToBePresentInElementValue
:和特定元素的元素值。visibilityOf
:一个可见的元素。titleContains
:标题包含我决定弄清楚如何解决我的用例,我的用例想要对特定的FindElements调用进行明确的等待,但不是全部,并且摆弄Implicit Waits感觉不洁和可怕。所以我为IWebDriver实现了一个扩展方法,它使用WebDriverWait(参见Selenium中的Explicit Waits)来实现它。
/// <summary>
/// Allows you to execute the FindElements call but specify your own timeout explicitly for this single lookup
/// </summary>
/// <remarks>
/// If you want no timeout, you can pass in TimeSpan.FromSeconds(0) to return an empty list if no elements match immediately. But then you may as well use the original method
/// </remarks>
/// <param name="driver">The IWebDriver instance to do the lookup with</param>
/// <param name="findBy">The By expression to use to find matching elements</param>
/// <param name="timeout">A timespan specifying how long to wait for the element to be available</param>
public static ReadOnlyCollection<IWebElement> FindElements(this IWebDriver driver, By findBy, TimeSpan timeout)
{
var wait = new WebDriverWait(driver, timeout);
return wait.Until((d) =>
{
var elements = d.FindElements(findBy);
return (elements.Count > 0)
? elements
: null;
});
}
