java - Selenium 网络驱动程序 | 拖放功能 | 没有异常，但代码不起作用

问题描述

我正在尝试将徽标拖放到容器中，但没有出现异常。我能够找到元素，并且相同的拖放代码适用于具有其他元素的另一个站点。但不知道为什么这在这里不起作用。任何人都可以提供帮助。

// Searching elements 

    driver.get(https://www.w3schools.com/html/tryit.asp?ilename=tryhtml5_draganddrop");
    driver.switchTo().frame(driver.findElement(By.name("iframeResult")));
    driver.manage().timeouts().implicitlyWait(10000, TimeUnit.MILLISECONDS);
    WebElement From = driver.findElement(By.id("drag1"));
    WebElement To = driver.findElement(By.id("div1"));

//Drag and Drop Action

    Actions builder = new Actions(driver);
    Action DragnDrop = builder.clickAndHold(From).moveToElement(To).release(To).build();
    DragnDrop.perform();

解决方案

根据我实现更稳定的拖放操作的经验，我们从 Actions 实现切换到 javascript 实现。是的，它可能看起来像一个 hack，但测试结果的持续假阴性使我们衡量风险并使用 js impl。（我们没有从头开始创建脚本，只是应用了互联网上的多个建议）

您可以将它用于您的案例，添加下面的代码而不是您使用的操作。
