Verification of Element in Viewport in Selenium

Question

How to verify whether an element is visible in viewport(visibility of browser) or not using Selenium?

I've tried with the below code, but Point object(Y value) returns huge value as page is scrollable. Here am getting element dimensions, location and Dimensions of Browser and comparing them.

Dimension weD = element.getSize(); //to get the element Dimensions
Point weP = element.getLocation(); // getting the location of the element in the page.

Dimension d = driver.manage().window().getSize(); // To get the browser dimensions
int x = d.getWidth(); //browser width
int y = d.getHeight(); //browser height
int x2 = weD.getWidth() + ewp.getX();
int y2 = weD.getHeight() + ewp.getY();
return x2 <= x && y2 <= y; 

If anyone has worked on it, Could you please share the solution?

It's not possible directly via the API, so you'll have to use a script injection.

The best way to determine if an element is visible in the viewport is to get the element at the supposed location with document.elementFromPoint. It returns null if it's not within the viewport and your element or a descendant if it is.

public static Boolean isVisibleInViewport(WebElement element) {
  WebDriver driver = ((RemoteWebElement)element).getWrappedDriver();

  return (Boolean)((JavascriptExecutor)driver).executeScript(
      "var elem = arguments[0],                 " +
      "  box = elem.getBoundingClientRect(),    " +
      "  cx = box.left + box.width / 2,         " +
      "  cy = box.top + box.height / 2,         " +
      "  e = document.elementFromPoint(cx, cy); " +
      "for (; e; e = e.parentElement) {         " +
      "  if (e === elem)                        " +
      "    return true;                         " +
      "}                                        " +
      "return false;                            "
      , element);
}
