使用Selenium WebDriver、Action类和JavaScript在Chrome 91上拖放不起作用

Question

在最新版本的chrome 91上，使用Selenium Action类或java脚本拖放元素不起作用。我尝试了所有可能的情况，例如使用以下方法

1. Javascript方法进行拖放

Java脚本方法1

function customEvent(typeOfEvent) {
    var event = document.createEvent("CustomEvent");
    event.initCustomEvent(typeOfEvent, true, true, null);
    event.dataTransfer = {
        data: {},
        setData: function (key, value) {
            this.data[key] = value;
        },
        getData: function (key) {
            return this.data[key];
        }
    };
    return event;
}
function dispatchEvent(element, event, transferData) {
    if (transferData !== undefined) {
        event.dataTransfer = transferData;
    }
    if (element.dispatchEvent) {
        element.dispatchEvent(event);
    } else if (element.fireEvent) {
        element.fireEvent("on" + event.type, event);
    }
}
function executeDrageAndDrop(element, target) {
    var dragStartEvent = customEvent('dragstart');
    dispatchEvent(element, dragStartEvent);
    var dropEvent = customEvent('drop');
    dispatchEvent(target, dropEvent, dragStartEvent.dataTransfer);
    var dragEndEvent = customEvent('dragend');
    dispatchEvent(element, dragEndEvent, dropEvent.dataTransfer);
}

Java脚本方法2：

function createEvent(typeOfEvent) {
var event =document.createEvent("CustomEvent");
event.initCustomEvent(typeOfEvent,true, true, null);
event.dataTransfer = {
data: {},
setData: function (key, value) {
this.data[key] = value;
},
getData: function (key) {
return this.data[key];
}
};
return event;
}

function dispatchEvent(element, event,transferData) {
if (transferData !== undefined) {
event.dataTransfer = transferData;
}
if (element.dispatchEvent) {
element.dispatchEvent(event);
} else if (element.fireEvent) {
element.fireEvent(\"on\" + event.type, event);
}
}

function simulateHTML5DragAndDrop(element, destination) {
var dragStartEvent =createEvent('dragstart');
dispatchEvent(element, dragStartEvent);
var dropEvent = createEvent('drop');
dispatchEvent(destination, dropEvent,dragStartEvent.dataTransfer);
var dragEndEvent = createEvent('dragend');
dispatchEvent(element, dragEndEvent,dropEvent.dataTransfer);
}

var source = arguments[0];
var destination = arguments[1];
simulateHTML5DragAndDrop(source,destination);", new Object[]{source, destination}

使用jQuery方法。JQuery

使用机器人类。

Locatable element = (Locatable)sourceElement ;
Point p= element.getCoordinates().inViewPort();
int sourceX=p.getX();
int sourceY=p.getY();

Locatable elementTarget = (Locatable)destElement;
Point Target= elementTarget.getCoordinates().inViewPort();
int targetX=Target.getX();
int targetY=Target.getY();


Robot robot = new Robot();
robot.mouseMove(sourceX, sourceY);
robot.mousePress(InputEvent.BUTTON1_MASK);
robot.mouseMove(targetX, targetY);
robot.mouseRelease(InputEvent.BUTTON1_MASK);

使用Selenium Touch动作。

    TouchActions builder = new TouchActions(driver);
builder.longPress(sourceElement).moveToElement(destElement).release(destElement).perform();

但没有一个解决方案对我有效。拖放是在之前的chrome版本89上进行的。

我附上了源代码的截图

谁能帮我一下吗？

Answer 1

尝试使用偏移量，我也面临同样的问题，鼠标点击，解决了使用下面的代码

    Locatable elementLocation = (Locatable)element ;
    Point p= elementLocation.getCoordinates().inViewPort();
    int sourceX=p.getX();
    int sourceY=p.getY();
    new Actions(driver).moveByOffset(sourceX, sourceY).click().build().perform();
