As a result, ('.click-me') fails and the function stops running. When you click on the SVG, the event.target is no longer the button.click-me element, but the path inside the SVG or the svg element itself. For example, if a 1000-unitwidth SVG is placed in a 500px width container, you can.

Pos_y = event.offsetY ? (event.offsetY) : event.pageY - document.getElementById("pointer_div").offsetTop Īdd below script code into your head part of website. An SVG is an HTML object, with nested items inside it. It’s tempting to think you can calculate the coordinates of an SVG point by applying multiplication factors. The second one is similar to position:absolute and is. Its coordinates will be denoted as clientX/clientY. The first system is like position:fixed and is calculated from the window top/left edge. Pos_x = event.offsetX ? (event.offsetX) : event.pageX - document.getElementById("pointer_div").offsetLeft The majority of JavaScript methods operate with one of the following two coordinate systems: Relative to the window and relative to the document.
It displays both coordinates in an HTML overlay. d3.transform (d3.select (this.parentNode).attr ('transform')).translate. So you need to get the transform attribute of the parent node and extract the translation from that. Following are the steps to get image coordinates using javascript Add Script This example uses the mousemove event to get two values from the MapMouseEvent object: the x-y point coordinates of the mouse cursor on the HTML map container and the lngLat coordinates of the cursor on the map. In your particular code, its quite difficult to get the position of the node because its determined by a translation of the parent element. In this article we set background image in div tag and then get coordinates using javascript for it. Let elem = document.Get Image Coordinates using Javascript, Using Javascript to find the coordinates on an image, javascript – get image pixel coordinates relative left top, Get Mouse coordinates inside a Div or an Image, Get an Element’s Position Using JavaScript,Mouse click position on the image, Get Image Coordinates With jQuery, How do I get mouse position relative to a picture, Get the coordinates of a mouse click on Canvas in Javascript. Here’s the picture of elem.getBoundingClientRect() output: If you scroll the page and repeat, you’ll notice that as window-relative button position changes, its window coordinates ( y/top/bottom if you scroll vertically) change as well. See the Pen Amethyst by Tiffany Brown ( webinista) on CodePen. If you tried to click on some white space, you might be really confused instead.

If you put your pointer in the right place (the shaded path) then you should have Smashing Magazine’s homepage open in a new browser tab. Javascript answers related to how to get mouse coordinates in javascript.
left/right – X-coordinate for the left/right rectangle edge.įor instance click this button to see its window coordinates: Try clicking or tapping the SVG image below.top/bottom – Y-coordinate for the top/bottom rectangle edge,.width/height – width/height of the rectangle (can be negative).Īdditionally, there are derived properties:.x/y – X/Y-coordinates of the rectangle origin relative to window,.The method elem.getBoundingClientRect() returns window coordinates for a minimal rectangle that encloses elem as an object of built-in DOMRect class. clientY – window-relative coordinate did change (the arrow became shorter), as the same point became closer to window top.Įlement coordinates: getBoundingClientRect.pageY – document-relative coordinate stayed the same, it’s counted from the document top (now scrolled out).
