Since I have a keyboard connected to my computer, I will use the space bar as the trigger to get the codes for reconstructing mouseCoordinates:Ĭonsole.log(JSON.stringify(mouseCoordinates)) I had to display several photos where the user can click over an interesting point and have its coordinates passed through a form. In order to reconstruct mouseCoordinates for moving the object, we need to use a third event trigger.
Using jQuery to listen to space bar presses Given these points, the following is the code snippet that prepares that global variable and registers a callback function that does the toggling when mouse clicks are detected: Inside that callback function, we toggle a global variable between the values of true and false to start/stop capture. In order to do so, we provide a JavaScript callback function to the $.mousedown function. Let's use mouse clicks to toggle the capturing of coordinates of the mouse as it moves.
