Question

你能否帮助我使用selenium和java自动拖放。

http://akserg.github.io/ng2-webpack-demo/#/dnd

我们在项目中使用的类似示例但我们拖放并没有发生，我们尝试了不同的方法来找到解决方案，但没有用。

如果您有任何人为此提供解决方案，请回复，我们将不胜感激。

请找到代码

public class ND2DND
{
    public static void main(String[] args) throws InterruptedException
    {
        WebDriver driver = new ChromeDriver();
        driver.get("http://akserg.github.io/ng2-webpack-demo/#/dnd");
        driver.manage().window().maximize();
        Thread.sleep(2000);
        WebElement sourceElement = driver
                .findElement(By.xpath("/html/body/app-root/demo-dnd/div/div/simple-dnd/div/div[1]/div/div[2]/div/div/div"));
        System.out.println(sourceElement.getText());

        // Element on which need to drop.
        WebElement destinationElement = driver
                .findElement(By.xpath("/html/body/app-root/demo-dnd/div/div/simple-dnd/div/div[2]/div/div[2]"));

        try
        {
            if (sourceElement.isDisplayed() && destinationElement.isDisplayed())
            {
                try
                {
                    Actions actions = new Actions(driver);
                    WebDriverWait wait = new WebDriverWait(driver, 20);
                    wait.until(ExpectedConditions.elementToBeClickable(sourceElement));
                    Action atc2 = actions.clickAndHold(sourceElement).moveToElement(destinationElement).release(destinationElement).build();
                    atc2.perform();
                    Thread.sleep(1000);
                    System.out.println("dropped");
                }
                catch (StaleElementReferenceException e)
                {
                    System.out.println("Element stale is continuing");
                }
            }
        }
        catch (Exception e)
        {
            System.out.println("Unable to drag and drop " + e);
        }
    }
}

提前致谢。

上述网址的解决方案：

wait.until（ExpectedConditions.elementToBeClickable（sourceElement））;

                String basePath = new File("").getAbsolutePath();

                final String JQUERY_LOAD_SCRIPT = (basePath + "/lib/jquery_load_helper.js");

                String jQueryLoader = readFile(JQUERY_LOAD_SCRIPT);


                JavascriptExecutor js = (JavascriptExecutor) driver;
                js.executeAsyncScript(
                        jQueryLoader /* , http://localhost:8080/jquery-1.7.2.js */);

                // ready to rock
                js.executeScript("jQuery(function($) { " + " $('input[name=\"q\"]').val('bada-bing').closest('form').submit(); "
                        + " }); ");
