硒网络驱动程序 |拖放功能 |没有例外，但代码不起作用

Question

我正在尝试将徽标拖放到容器中，但没有得到异常。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。任何人都可以协助。

// 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();

根据我的经验，为了实现更稳定的拖放操作，我们从操作实现切换到 JavaScript 实现。是的，它可能看起来像一个黑客，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(

您可以将其用于您的案例，添加下面的代码而不是您使用的操作。

driver.executeScript("function dnd(elemDrag, elemDrop) {n" +
"    var DELAY_INTERVAL_MS = 100;n" +
"    var MAX_TRIES = 10;n" +
"    var dragStartEvent;n" +
"    if (!elemDrag || !elemDrop) {n" +
"        return false;n" +
"    }n" +
"    function fireMouseEvent(type, elem, dataTransfer) {n" +
"        var evt = document.createEvent('MouseEvents');n" +
"        evt.initMouseEvent(type, true, true, window, 1, 1, 1, 0, 0, false, false, false, false, 0, elem);n" +

"            evt.dataTransfer = dataTransfer || createNewDataTransfer();n" +
"        }n" +
"        elem.dispatchEvent(evt);n" +
"        return evt;n" +
