我想在java中使用selenium webdriver拖放分层列表。有关更多详细信息，请参阅演示链接。

我尝试了以下方法：-

1. 获取源元素
2. 使用class=dd-占位符创建div
3. 拖动源元素并放到新创建的div元素上

错误：-无法在新创建的div元素上删除源元素。

我怎么能做到这一点。是否可以使用selenium webdrive。

该方法使用Javascript将webelement从一个位置拖放到另一个位置。不要被它的javascript困住：）。只需通过提供from和to参数来使用该方法。祝你好运

public void dragAndDrop(WebElement from, WebElement to) {
    js.executeScript("function createEvent(typeOfEvent) {\n" + "var event =document.createEvent(\"CustomEvent\");\n"
            + "event.initCustomEvent(typeOfEvent,true, true, null);\n" + "event.dataTransfer = {\n" + "data: {},\n"
            + "setData: function (key, value) {\n" + "this.data[key] = value;\n" + "},\n"
            + "getData: function (key) {\n" + "return this.data[key];\n" + "}\n" + "};\n" + "return event;\n"
            + "}\n" + "\n" + "function dispatchEvent(element, event,transferData) {\n"
            + "if (transferData !== undefined) {\n" + "event.dataTransfer = transferData;\n" + "}\n"
            + "if (element.dispatchEvent) {\n" + "element.dispatchEvent(event);\n"
            + "} else if (element.fireEvent) {\n" + "element.fireEvent(\"on\" + event.type, event);\n" + "}\n"
            + "}\n" + "\n" + "function simulateHTML5DragAndDrop(element, destination) {\n"
            + "var dragStartEvent =createEvent('dragstart');\n" + "dispatchEvent(element, dragStartEvent);\n"
            + "var dropEvent = createEvent('drop');\n"
            + "dispatchEvent(destination, dropEvent,dragStartEvent.dataTransfer);\n"
            + "var dragEndEvent = createEvent('dragend');\n"
            + "dispatchEvent(element, dragEndEvent,dropEvent.dataTransfer);\n" + "}\n" + "\n"
            + "var source = arguments[0];\n" + "var destination = arguments[1];\n"
            + "simulateHTML5DragAndDrop(source,destination);", from, to);

}

我发现拖放功能有点不同，具体取决于您使用的浏览器，我必须在拖放位置添加偏移量，以使其在ChromeFirefox和IE中始终如一地工作。

这是一个C#代码段，但java应该类似。这个实例中的目标是我用JS插入的占位符div，就像你的方法一样

Actions act = new Actions(WebDriver);
act.ClickAndHold(source);
act.MoveToElement(target);
act.MoveByOffset(0, 5); //Minimum 1 pixel offset for Chrome, 5 for IE 
act.Release(source);
act.Build().Perform();
