Layerx vs offsetx

This simple conditional will get us our mouse position on all modern desktop browsers that support canvas, using either e.layerX and e.layerY or e.offsetX and e.offsetY. Use these values to update our _mouse object by assigning it an x and a y property to hold the current mouse position - in this case, the position where it was clicked.

offsetX Definition and Usage. The offsetX property returns the x-coordinate of the mouse pointer, relative to the target element.. Tip: To get the y-coordinate, use the offsetY property. HRESULT value = object.get_layerX(* p); Property values. Type: long. The x-coordinate.

25.10.2020 Layerx vs offsetx

layerX / layerY are properties of MouseEvent objects defined by Gecko-based browsers (Firefox et al.). Some say they're substitutes for offsetX / offsetY - they're not. They're the position of the mouse relatively to the "closest positioned element", i.e. an element whose position style property is not static.

an element whose position style property is not static. 2019/03/27 I use jQuery 1.4.2 and observed that the attributes layerX/layerY (e.g. Firefox) and offsetX/offsetY (e.g. IE) of mouse events like click are not normalized: In both browsers all four attributes are available on the jQuery Event object.

offsetX is the offset every time it's requested (as it might change inside the handler) But the Blink/WebKit behavior is neither! It is: offsetX is the offset at the first time it is requested, and does not correspond to pageX/clientX. So, IMO it is clear when offsetX/Y should be calculated, and the spec is correct. The clientX read-only property of the MouseEvent interface provides the horizontal coordinate within the application's viewport at which the event occurred (as opposed to the coordinate within the page). Avoid Layout Thrashing — the easy way Alexander Farkas - boffinHouse. What is Layout Thrashing?

Our solutions are used across multiple industries and domains to provide rich insight into the operational performance of the Network and the UC infrastructure. The layerX property is rarely useful, use other event properties instead. To get the position relative to the top-left corner of the document, use the pageX and pageY properties. If you need the position of the mouse pointer relative to the top-left corner of the browser window's client area, use the clientX and clientY properties. Chrome, IE9, and Firefox support the offsetX/Y like this, passing in the event from the click handler. function getRelativeCoords(event) { return { x: event.offsetX, y: event.offsetY }; } Most modern browsers also support layerX/Y, however Chrome and IE use layerX/Y for the absolute offset of the click on the page including margin, padding, etc. AFAIK, there is no standard way to understand the touch/click inside a generic DOM element and if you guys remove layerX and layerY it would be really nice if you can introduce at least something like: document.getElementPagePosition(HTMLElement) // returns {pageX: 20, pageY: 738} So that at least developers can subtract these coordinates In this tutorial I show you how to use the inset feature to highlight a font or image as opposed to using an offset or shadow layer.
