java - 通过 selenium webdriver 选择日期

Question

我无法使用 xpath 选择日期或找到实际日期，或者我想在 vipcars.com 上选择当前日期旁边的一个日期。这是我正在使用的代码..

public static void main(String args[])
    {

         System.setProperty("webdriver.chrome.driver","D:\\chromedriver.exe");//any driver can be initialized like this just by replacing driver here.
         DesiredCapabilities capabilities=DesiredCapabilities.chrome();
         capabilities.setCapability("chrome", true);
         WebDriver driver = new ChromeDriver(capabilities);

         driver.manage().window().maximize();

         // Test URL
         driver.get("https://www.vipcars.com/");

         driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
         String parent = driver.getWindowHandle();
         driver.switchTo().frame(driver.findElement(By.cssSelector("iframe[id='supplycarsIframe']")));

         driver.findElement(By.id("pickup_country")).click();        
         Select country = new Select(driver.findElement(By.id("pickup_country")));   
         country.selectByValue("441");


         driver.findElement(By.id("pickup_city")).click();       
         Select city = new Select(driver.findElement(By.id("pickup_city")));     
         city.selectByValue("9747");

         driver.findElement(By.id("pickup_location")).click();       
         Select location = new Select(driver.findElement(By.id("pickup_location")));     
         location.selectByValue("14927");

         driver.findElement(By.id("pickdate")).click(); //calender clicks   
         driver.findElement(By.xpath("//input[@placeholder='From']")); //id found
         **driver.findElements(By.xpath("//table[@class='ui-datepicker-calendar']//tr[3]/td[6]"));** 



List<WebElement> allDates = (List<WebElement>) ((WebElement) driver.findElements(By.xpath("//table[@class='ui-datepicker-calendar']//tr[3]/td[6]"));
        (WebElement) allDates).click();

控制台错误消息:

java.util.ArrayList cannot be cast to org.openqa.selenium.WebElement

Answer 1

您的代码中的问题是 (List<WebElement>) ((WebElement) driver.findElements(By.xpath("//table[@class='ui-datepicker-calendar']//tr[3]/td[6]"));您将 List 转换为 WebElement，这是不可能的。之后你想将其转换为 List，这也是不可能的。

你期望什么，你想做什么？以下是一些纠正代码的示例:

//this will return a List<WebElement> 
driver.findElements(Locator locator);

//this will return a WebElement
driver.findElement(Locator locator);

//if you know that there is only one element which you want to click, use this
driver.findElement(By.xpath("//table[@class='ui-datepicker-calendar']//tr[3]/td[6]")).click();

//if there are more than one WebElements which can be found by that xpath locator, use this
List<WebElement> allDates = driver.findElements(By.xpath("//table[@class='ui-datepicker-calendar']//tr[3]/td[6]"));
//now you can iterate through the list and do what you want, e.g. click every element
for (WebElement date : allDates) {
    date.click();
}
