执行时找不到xpath

Question

public class draganddrop
{
    public static void main(String[] args) throws InterruptedException
    {
        // opening site for practicing user interaction by mouse using webdriver and action class
        WebDriver driver = new ChromeDriver();
        String URL = "http://www.dhtmlx.com/docs/products/dhtmlxTree/index.shtml";
        driver.get(URL);

        // It is always advisable to Maximize the window before performing DragNDrop action
        driver.manage().window().maximize();
        driver.manage().timeouts().implicitlyWait(10000, TimeUnit.MILLISECONDS);
        WebElement From = driver.findElement(By.xpath(".//*[@id='treebox1']/div/table/tbody/tr[2]/td[2]/table/tbody/tr[2]/td[2]/table/tbody/tr[1]/td[4]/span"));
        WebElement To = driver.findElement(By.xpath(".//*[@id='treebox2']/div/table/tbody/tr[2]/td[2]/table/tbody/tr[2]/td[2]/table/tbody/tr[2]/td[2]/table/tbody/tr[1]/td[4]/span"));
        Actions builder = new Actions(driver);
        Action dragAndDrop = builder.clickAndHold(From).moveToElement(To).release(To).build();
        dragAndDrop.perform();

        Thread.sleep(2000);
    }
}

错误消息

线程“main”org.openqa.selenium.nosuchelementException：没有这样的元素：找不到元素：{“method”：“XPath”,“Selector”：“.//*[@id='TreeBox1']/div/table/tbody/tr[2]/td[2]/table/tbody/tr[2]/td[2]/table/tbody/tr[2]/td[2]/table/tbody/tr[1]/td[2]/table/td[2]/table/tbody/tr[1]/td[4]/span”}

Answer 1

我不知道是什么让您想到了XPath，但从源代码来看，它似乎不对。

替换

WebElement From = driver.findElement(By.xpath(".//*[@id='treebox1']/div/table/tbody/tr[2]/td[2]/table/tbody/tr[2]/td[2]/table/tbody/tr[1]/td[4]/span"));

对于

WebElement From = driver.findElement(By.xpath(".//*[@id='treebox1']"));
