你可以使用下面的方法

WebDriverWait wait = new WebDriverWait(driver, new TimeSpan(0,0,5));
wait.Until(ExpectedConditions.ElementToBeClickable((By.Id("login")));

我正在用这个，效果很好:

public static bool elexists(By by, WebDriver driver)
{
    try
    {
        driver.FindElement(by);
        return true;
    }
    catch (NoSuchElementException)
    {
        return false;
    }
}

public static void waitforelement(WebDriver driver, By by)
{
    for (int i = 0; i < 30; i++)
    {
        System.Threading.Thread.Sleep(1000);
        if (elexists(by, driver))
        {
            break;
        }
    }
}

当然，您可以添加超过30次的尝试，并将周期缩短到1秒以内进行检查。

用法:

waitforelement(driver, By.Id("login"));
IWebElement login = driver.FindElement(By.Id("login"));
login.Click();

下面是如何在Selenium中等待一个条件:

    WebDriverWait wait = new WebDriverWait(m_driver, TimeSpan.FromSeconds(10));
    wait.Until(d => ReadCell(row, col) != "");

ReadCell(row, col) != ""可以是任何条件。这样做是因为:

它是我的 允许内联

你可以在c#中找到类似的东西。

这是我在JUnit - Selenium中使用的

WebDriverWait wait = new WebDriverWait(driver, 100);
WebElement element = wait.until(ExpectedConditions.elementToBeClickable(By.id("submit")));

导入相关的包。

我们可以这样实现:

public static IWebElement WaitForObject(IWebDriver DriverObj, By by, int TimeOut = 30)
{
    try
    {
        WebDriverWait Wait1 = new WebDriverWait(DriverObj, TimeSpan.FromSeconds(TimeOut));
        var WaitS = Wait1.Until(SeleniumExtras.WaitHelpers.ExpectedConditions.PresenceOfAllElementsLocatedBy(by));
        return WaitS[0];
    }
    catch (NoSuchElementException)
    {
        Reports.TestStep("Wait for Element(s) with xPath was failed in current context page.");
        throw;
    }
}

你可以使用下面的方法

WebDriverWait wait = new WebDriverWait(driver, new TimeSpan(0,0,5));
wait.Until(ExpectedConditions.ElementToBeClickable((By.Id("login")));
