無法執行拖放操作，即使執行的代碼沒有任何錯誤

Question

即使執行拖放操作時沒有發生任何錯誤，也無法查看AnjularJS應用程序中拖動的元素。

下面是代碼：

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]")); 

下面是沒有誤差，並執行不同的方法：

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(); 

也執行JavaScript的方法：但沒有運氣也執行沒有錯誤，但無法執行在UI中拖放動作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會在沒有任何錯誤的情況下編譯和執行，但無法在UI中執行拖放操作（請參閱幫助）。

試過所有可能的組合，我知道可以讓任何人知道我是否錯過了一些東西？ 僅供參考使用Chrome 53和Firefox 42會有什麼不同嗎？ 有沒有其他工具可以滿足我的要求？

Answer 1

只要確保網頁中顯示的元素不是HTML5網頁元素即可。由於硒不支持對HTML5元素執行操作。

看看http://elementalselenium.com/tips/39-drag-and-drop瞭解如何使用javascript對HTML5元素執行拖放操作。
