Measuring code execution performance is an important way to identify bottlenecks. ![]() Measuring code execution performance in JavaScript by Gav For a more detailed list of mouse events you could have a read of this.įirst we set up an event listener for our event: document.addEventListener('mousemove', (event) => `) Īs a result, if you now open your console you will see that every time you move the mouse there will be a log of the mouse coordinates ‘helpfully’ spammed all over your screen. ![]() In this case we will use ‘mousemove’ to log the current X and Y coordinates of the mouse to the console. To get the current mouse position we are going to trigger a mouse event. So how can we get the mouse position from a mouse event? Getting the current X and Y coordinates from an event As far as I’m aware it isn’t possible to get the current mouse position without triggering a mouse event. I would usually include some catch like ‘get the current mouse position without using an event’. This simple problem was something I found myself googling fairly often when I was new to coding. To do all of these things you need to know the current mouse position relative to the screen. Would you like to be able to open a modal, or a context menu? Maybe you are making a browser game, or simply adding a sparkly trail to your mouse. Now all we have to do is make a new instance of the HeadImage prototype in the init function for every rotating head we want on our page and then call its setImageDirection function in the event triggered by mousemove.Facebook Share Twitter Share LinkedIn Share If(mouseX >imageLeft & mouseX imageTop & mouseY imageBottom) else if(mouseX > this.imageRight & mouseY. The process is simple enough: There is a single tag with a default source for the image that is supposed to be displayed by default (in my case, the image where I am facing the camera). This approach was the first one I tried, because it uses the least amount of repetitive html code. Variant A: One tag, load source through jquery's. Nevertheless I will show you the different approaches I tried out, in order to make you understand why I chose the variant in use now. I tried multiple approaches on how to load the images, but only one gave satisfactory results. Which image is displayed depends on the position of the mouse cursor. First things first: Loading the imagesĪs you might have noticed, I use nine different images to simulate the rotating effect. I mean, who doesn't want to see his own head spin around like a maniac for hours a day?Īlright, without further a-do, let me tell you how I built this mind-blowing, can't-live-without, got-to-have, life-changing feature. And don't worry, I am going to explain to you step by step how I got this head to follow your cursor. But we still love it and got great feedback from customers, friends and friendly developers.Īwesome, I know. Have you seen our former contact page? We had the rotating heads integrated.
