You can call GetMouseMovePointsEx to get the mouse position and history. Removing all the stuff about the offset, you can easily get the X, Y coordinates of the click relative to the browser window. The below code will give you the X, Y coordinates of a mouse click within a given box. The color should telll you where the user clicked. Take the XY from the mouse, and see what color pixel you have in the bitmap file at that location. You could use a bitmap file, which uses XY coordinates. You might want to create an image composed of a series of "frames", which could isolate each area. This nifty functionality is achieved using Access Keys. For Firefox, you'll need to hold down the 'Shift' and 'Alt' keys simultaneously, along with the 'z' accesskey. How to get xy coordinates of mouseĬursor X & Y Coordinates plus Browser Access Keys On this page, press and hold the 'Alt' key, then press the 'Z' key to toggle the X/Y coordinates layer on and off. A MouseEvent is fired when we can press, release or click (press followed by release) a mouse button (left or right button) at the source object or position the mouse pointer at (enter) and away (exit) from the source object. We can implement a MouseListener interface when the mouse is stable while handling the mouse event. Mouselistener is working with the help of keyword implements and this listener interface can be gained from the package. It can also be entering or exiting the window area. Changes of the mouse can be pressing, clicking, and releasing it. In Java, MouseListener is a class that gets notified when there is a change in the mouse state. Tip: To get the vertical coordinate (according to the client area) of the mouse pointer, use the clientY property. The clientX property returns the horizontal coordinate (according to the client area) of the mouse pointer when a mouse event was triggered. If the start and end value are the same, it means that there's no selected text and the start value (or end value) is the position of the cursor. The mini library is a wrapper made in jQuery for tipical tasks related to the text selection and position within a text input or textarea element (getSelection, setSelection, deleteText etc). For a more detailed list of mouse events you could have a read of this. In this case we will use ‘mousemove’ to log the current X and Y coordinates of the mouse to the console. Į get the current mouse position we are going to trigger a mouse event. This text is displayed if your browser does not support HTML5 Canvas. Var flip = document.getElementById('flip') second, how can i write a code that works for ie, firefox, chrome, safari and opera? I have two questions, first, what is the right thing to do to get the correct mouse position under firefox. but it seems that layerX is the position of my mouse relative to the web page, not the position of the canvas. This works very well in chrome, however when it comes to firefox, it doesn't work. Right now, I am using x=event.offsetX to get the mouse position. My code is simple, but I have a problem getting the mouse cursor position within the canvas. When the mouse move, I draw red squares under my mouse. All I want to do is a simple html5 drawing example.
