![]() ![]() ![]() If you are not using jQuery's normalized events but still have access to the jQuery, you can use to normalize the event object. If you are doing event handling with jQuery, it will automatically normalize pageX and pageY for you. 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. To get the y-coordinate of the mouse, use the pageY property. The only major browser that does not support these properties is IE8. The screenX property returns the x (horizontal) coordinate of a window, relative to the screen. property (event) Retrieves the x-coordinate of the mouse pointer relative to the top-left corner of the document. Know that only clientX, clientY, screenX, and screenY are part of the W3C Spec. The differences and the use case of these properties are described below: The screenX and screenY property: The screenX and screenY are read-only properties that provide horizontal and vertical coordinates respectively relative to the global, or screen coordinates. QuirksMode has a great compatibility table that details inconsistencies in the non-standard properties. If none of the ancestor elements have positioning, the mouse position is relative to the document (like pageX, pageY). screenX/Y are relative to the physical screen. The screenX property retrieves the position of the mouse in physical pixel size in Firefox, Opera, Google Chrome, Safari and in Internet Explorer earlier than version 8, while from version 8, it returns the position in logical pixel size. Mouse position relative to the closest positioned ancestor element. pageX/Y coordinates are relative to the top left corner of the whole rendered page (including parts hidden by scrolling), while clientX/Y coordinates are relative to the top left corner of the visible part of the page, 'seen' through browser window. x, yĮquivalent to clientX, clientY, but is unsupported by some browsers. Mouse position relative to the html document (i.e. The Window.screenX read-only property returns the horizontal distance, in CSS pixels, of the left border of the users browser viewport to the left side of the screen. This is implemented very inconsistently between browsers. It is supported in all modern browsers: event.pageX is not supported in Internet Explorer 11 (or earlier). I calculate the expected positions as follows: page Relative to the document client Old definition: relative to the visual viewport clientX/Y pageX/Y - window. This test interprets the coordinates as page coordinates (i.e. clientX/Y pageX/Y screenX/Y Zoom factor: 100. Note: An alias of screenX was implemented across modern browsers in more recent times Window.screenLeft. The differences between pageX and pageY and screenX and screenY: let pX event.pageX let pY event.pageY let sX event.screenX let sY event.screenY Try it Yourself Browser Support event.pageX is a DOM Level 4 (2015) feature. Click on the page to set the three test layers. Mouse position relative to the target element. The Window.screenX read-only property returns the horizontal distance, in CSS pixels, of the left border of the user's browser viewport to the left side of the screen. In JavaScript: pageX, pageY, screenX, screenY, clientX and clientY returns a number which indicates the number of physical pixels a point is from the reference. Mouse position relative to the user's physical screen. Tip: To get the vertical coordinate (according to the document) of the mouse pointer, use the pageY property. ![]() pageX clientX + width of the scrolled-out horizontal part of the document. IE doesn't provide much in the way of window properties, but oddly enough, a click event object will provide you with the screen location of the click.Mouse position relative to the browser's visible viewport. The pageX property returns the horizontal coordinate (according to the document) of the mouse pointer when a mouse event was triggered. The two coordinate systems are connected by the formula: pageY clientY + height of the scrolled-out vertical part of the document. You can use the outer/innerWidth and outer/innerHeight properties of the window object to approximate a little closer. Var left = $("#myelement").offset().left + window.screenX Įxact position depends on what toolbars are visible. But for other browsers, a close approximation of position is: var top = $("#myelement").offset().top + window.screenY The Touch.screenY property is the vertical coordinate of a touch point relative to the screen in CSS pixels. Window.screenX/Y are not supported on IE. The Touch.screenX property is the horizontal (x) coordinate of a touch point relative to the screen in CSS pixels. ![]()
