Question

我已经使用各种定位器来定位下拉列表的Web元素，但是每次遇到此错误时它都无法正常工作：无法找到元素

我正在尝试给定的URL登录并选择日历 “ https://classic.crmpro.com/

在使用隐式等待后，我使用以下方法进行定位

driver.manage().timeouts().implicitlyWait(500, TimeUnit.SECONDS);

driver.findElement（By.xpath（“ // a [@href ='https://classic.crmpro.com/system/index.cfm?action=calendar&sub=default']”）））。click（）;
driver.findElement（By.xpath（“ // * [@ id ='navmenu'] / ul / li [2] / a”））。click（）;
driver.findElement（By.xpath（“ // * [@ title ='Calendar']”））。click（）;
driver.findElement（By.xpath（“ // * [包含（text（），'Calendar'）]”））））。click（）;
driver.findElement（By.xpath（“ // * [@ title ='Calendar']”）））。click（）; Thread.sleep（1000）;

每次都会抛出类似以下的错误：

请让我知道我该怎么办。

Answer 1

您的问题解决了吗？如果没有，请执行此操作。

您要表示的元素位于iframe内，因此您必须先进行切换。

这是iframe，我的意思是：By.name("mainpanel")

登录后，您可以执行以下操作：

new WebDriverWait(driver, 20).until(ExpectedConditions.frameToBeAvailableAndSwitchToIt(By.name("mainpanel")));
driver.findElement(By.xpath("//*[@title='Calendar']")).click();

它将单击calendar，但是如果您只想移动到element并显示下拉菜单，请执行以下操作：

new WebDriverWait(driver, 20).until(ExpectedConditions.frameToBeAvailableAndSwitchToIt(By.name("mainpanel")));
Actions act = new Actions(driver);
act.moveToElement(driver.findElement(By.xpath("//*[@title='Calendar']"))).perform();

正在导入：

import org.openqa.selenium.support.ui.WebDriverWait;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.interactions.Actions;

对不起，我建议更改您的凭据并将其从此站点中删除。

希望这会有所帮助。
