硒获得元素的自然高度和宽度.不应该依赖style属性.GetSize(),GetLocation()和getRect()都无法执行此操作

Question

这是场景.

当我使用GetSize(),GetLocation()函数对图像ID'FlashID1x'时它总是给出250,300,但元素的实际高度和宽度是1 X 1,这基本上是错误的.

这是我的目标dom:

<img id="FlashID1x" border="0" width="300" height="250" style="width:300px;height:250px;" alt="" src="http://s2.adform.net/Banners/invisible.gif?bv=2"/>

这是我的代码:

System.out.println("total : "+iframe.size());  
//driver.switchTo().frame(frame);

org.openqa.selenium.Point point=driver.findElement(By.xpath(".//*[@id='FlashID1x']")).getLocation();  
System.out.println("X Position : "+point.x);  
System.out.println("Y Position : "+point.y);  

System.out.println("X getX : "+point.getX());  
System.out.println("Y gety : "+point.getY());  

Rectangle pointer=driver.findElement(By.xpath(".//*[@id='FlashID1x']")).getRect();
System.out.println("height : "+pointer.hashCode();
System.out.println(" width : "+pointer.getWidth());  

System.out.println("getHeight : "+pointer.getHeight());  
System.out.println(" getWidth : "+pointer.getWidth());

getSize方法返回呈现的Web元素大小,而不是图像的物理大小.如果你的目标是获得内在的高度和重量,那么你可以尝试获得naturalWidth和naturalHeight属性:

WebDriver driver = new FirefoxDriver();
WebDriverWait wait = new WebDriverWait(driver, 20);
driver.get("http://stackoverflow.com");

// get the intrinsic size with the getAttribute method
WebElement ele = driver.findElement(By.cssSelector("img"));
String naturalWidth = ele.getAttribute("naturalWidth");
String naturalHeight = ele.getAttribute("naturalHeight");

// get the intrinsic size with a piece of Javascript
ArrayList result = (ArrayList)((JavascriptExecutor) driver).executeScript(
        "return [arguments[0].naturalWidth, arguments[0].naturalHeight];", ele);
Long naturalWidth2 = (Long)result.get(0);
Long naturalHeight2 = (Long)result.get(1);
