| This tests that calling <code>document.elementFromPoint()</code> on an element displayed in a region's |
| visible overflow will actually return that element (and not the element "underneath" it).<br> |
| You should see "PASS" being displayed below. |
| <div id="content"><span class="spacer"></span>This text has <span class="highlite">overflow</span></div> |
| <div id="result"> </div> |
| <div id="parent"> |
| <div id="region"> |
| <p></p> |
| </div> |
| </div> |
| <script type="text/javascript"> |

| function runScript() { |
| var region, regionBox, target, targetBox, fromPoint; |
| |
| region = document.querySelector("#region"); |
| region.scrollTop = 200; |
| |
| regionBox = region.getBoundingClientRect(); |
| |
| document.body.offsetTop; |
| |
| target = document.querySelector(".highlite"); |
| targetBox = target.getBoundingClientRect(); |
| fromPoint = document.elementFromPoint(targetBox.left + targetBox.width/2, targetBox.top + targetBox.height/2); |
| |
| // Check we get the same element via DOM selection and via elementFromPoint() AND |
| // the element we get is in the visible part of the region |
| if ((fromPoint == target) && (targetBox.bottom <= regionBox.bottom)) { |
| result.innerHTML = "PASS"; |
| } else { |
| result.innerHTML = "FAIL"; |
