拖放在使用 Selenium WebDriver、Action Class 和 JavaScript 的 Chrome 91 上不起作用

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。我已经尝试了所有可能的情况，例如使用以下方法

1. Javascript 方法拖放。

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 脚本方法二：

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}

1. 使用 jQuery 方法。 jQuery

           }
       }
   });
   
   })( jQuery );

2. 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);
   

3. 使用 Selenium 触摸操作。

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

但是没有一个解决方案对我有用。拖放在以前的 chrome 版本 89 上工作。

我附上了使用黄色和红色下划线突出显示的源和目标元素的屏幕截图。

谁能帮我解决这个问题？

Answer 1

尝试使用偏移量我也面临同样的鼠标点击问题，使用下面的代码解决了

    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();
