无法执行拖放操作，即使执行的代码没有任何错误

Question

即使执行拖放操作时没有发生任何错误，也无法查看AnjularJS应用程序中拖动的元素。

下面是代码：

WebElement draggable = driver.findElement(By.xpath("//*[@id='page-content-wrapper']/div[2]/div[3]/div[4]/div/div[2]/div/div/div[2]/div/div[1]/ul/li/ul/li[2]/span/span[1]")); 
WebElement droppable = driver.findElement(By.xpath(".//*[@id='page-content-wrapper']/div[2]/div[3]/div[3]/div[2]/div[1]/div[1]/div/div[6]/div[2]/div[1]")); 

下面是没有误差，并执行不同的方法：

1) 
Actions builder = new Actions(driver); 
     builder.keyDown(Keys.CONTROL).click(draggable).click(droppable). keyUp(Keys.CONTROL).build().perform(); 

2)Method 2 
Actions builder = new Actions(driver); 
      builder.clickAndHold(draggable).moveToElement(droppable).build(); 
      builder.dragAndDrop(draggable, droppable).perform(); 

3)Method 3 
Actions action = new Actions(driver); 
      Thread.sleep(1000); 
      action.clickAndHold(draggable2).build().perform(); 
      action.moveToElement(droppable2).build().perform(); 
      action.release(droppable2).build().perform(); 

4) 
Method 4 
Actions actions = new Actions(driver); 
     browser.actions() 
     .mouseDown(draggable2) 
     .mouseMove(draggable2) 
     .mouseUp(droppable2) 
     .perform(); 

也执行JavaScript的方法：但没有运气也执行没有错误，但无法执行在UI中拖放动作enter image description here

A) public static void DragAndDropJS2(WebElement source, WebElement destination, WebDriver driver) throws Exception 
    { 
     // JavascriptExecutor js = (JavascriptExecutor) driver; 
     String xto=Integer.toString(source.getLocation().x); 
     String yto=Integer.toString(destination.getLocation().y); 
     ((JavascriptExecutor)driver).executeScript("function simulate(f,c,d,e){var b,a=null;for(b in eventMatchers)if(eventMatchers[b].test(c)){a=b;break}if(!a)return!1;document.createEvent?(b=document.createEvent(a),a==\"HTMLEvents\"?b.initEvent(c,!0,!0):b.initMouseEvent(c,!0,!0,document.defaultView,0,d,e,d,e,!1,!1,!1,!1,0,null),f.dispatchEvent(b)):(a=document.createEventObject(),a.detail=0,a.screenX=d,a.screenY=e,a.clientX=d,a.clientY=e,a.ctrlKey=!1,a.altKey=!1,a.shiftKey=!1,a.metaKey=!1,a.button=1,f.fireEvent(\"on\"+c,a));return!0} var eventMatchers={HTMLEvents:/^(?:load|unload|abort|error|select|change|submit|reset|focus|blur|resize|scroll)$/,MouseEvents:/^(?:click|dblclick|mouse(?:down|up|over|move|out))$/}; " + 
       "simulate(arguments[0],\"mousedown\",0,0); simulate(arguments[0],\"mousemove\",arguments[1],arguments[2]); simulate(arguments[0],\"mouseup\",arguments[1],arguments[2]); ", 
       source,xto,yto); 

    } 



    B) public static void DragAndDropJS(WebElement source, WebElement destination, WebDriver driver) throws Exception 
    { 
     JavascriptExecutor js = (JavascriptExecutor) driver; 
     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);",source, destination); 
     Thread.sleep(1500); 

    } 



    c) public static void DragAndDropJS1(WebElement source, WebElement destination, WebDriver driver) throws Exception 
    { 
     JavascriptExecutor js = (JavascriptExecutor) driver; 
     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" +"}\n" +"\n" +"var source = arguments[0];\n" +"var destination = arguments[1];\n" +"simulateHTML5DragAndDrop(source,destination);",source, destination); 
     Thread.sleep(1500); 
    } 

以上提到的所有方法和命令都会在没有任何错误的情况下编译和执行，但无法在UI中执行拖放操作（请参阅帮助）。

试过所有可能的组合，我知道可以让任何人知道我是否错过了一些东西？ 仅供参考使用Chrome 53和Firefox 42会有什么不同吗？ 有没有其他工具可以满足我的要求？

Answer 1

只要确保网页中显示的元素不是HTML5网页元素即可。由于硒不支持对HTML5元素执行操作。

看看http://elementalselenium.com/tips/39-drag-and-drop了解如何使用javascript对HTML5元素执行拖放操作。
