The transform() method acts as a full getter without an argument: element. 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. Set multiple attributes at once: rect.attr(, someMatrix) transform() as getter Try clicking or tapping the SVG image below. Set a single attribute: rect.attr('x', 50)

How do I contribute or fix something in the docs?Īnimate yes (only for numbers, arrays, colors.

I need help getting something to work.

How can I modify an element that already exists in the dom?.

Two SVG's are generated when I initialize SVG.js.

Var mp = webMercatorUtils.webMercatorToGeographic(evt.mapPoint) ĭom.byId("info").innerHTML = mp.x.toFixed(3) + ", " + mp.y. the map is in web mercator but display coordinates in geographic (lat, long) After I click any part of the group element, I get an event object with coordinates relative to the HTML page ( evt.clientX and evt.clientY ).

after map loads, connect to listen to mouse move & drag events "esri/map", "esri/geometry/webMercatorUtils", "dojo/dom", In addition, you may have a translation applied through the transform attribute which changes the reference point of any coordinates. For circle s for example, the cx and cy attributes determine the center position.

Var mp = (evt.mapPoint) ĭojo.byId("info").innerHTML = mp.x + ", " + mp.y Code The way to determine the coordinates depends on what element you're working with. Following is how the function gets the coordinates and writes them to the "info" tag: Positions are then measured in pixels from the top left corner, with the positive x. That is, the top left corner of the document is considered to be the point (0,0), or point of origin. To display the coordinates in geographic, use the utility object to perform the conversion. For all elements, SVG uses a coordinate system or grid system similar to the one used by canvas (and by a whole lot of other computer drawing routines). Since the map data is in Web Mercator the resulting coordinates will display in Web Mercator. By default when you use mouse wheel or pinch to zoom, panzoom uses mouse coordinates to determine the central point of the zooming operation. These events both pass map point coordinates to the showCoordinates function.

One listens for onMouseMove and the other listens for onMouseDrag, but they both call the function showCoordinates:ĭojo.connect(map, "onMouseMove", showCoordinates) ĭojo.connect(map, "onMouseDrag", showCoordinates)

However, the viewBox attribute defines the portion of that canvas to display.

These two lines add event listeners to the map. To test this in a simple manner, I put three rectangles in global svg space at (100, 500), (500, 500), (1000, 500), and (1000, 200). The first (var map) is the name of the object, the second ( esri.Map) is the name of the class, and the third ("map") is the name of the div which will contain the map. "Map" appears three times in the above line.

This is made possible by event listeners that update the the x and y coordinates while the mouse moves. This sample reports the coordinates of the mouse pointer as the user hovers or drags the mouse across the map.
