I'm currently working on a project where I need to implement horizontal movement for a DOM element. The movement should start on mousedown, continue on mousemove, and end on mouseup.
This task is especially challenging due to the site's numerous animations and elements, making performance a top priority. However, I have noticed a slight delay in the element's movement, causing it to lag behind the mouse. This issue is not ideal and affects the overall appearance of the site.
Here's a snippet of the current code I have:
var offset = 0, startX;
$('.draggable').on('mousedown', function (e) {
startX = e.pageX;
})
.on('mouseup', function() {
startX = null;
})
.on('mousemove', function (e) {
if(startX) {
newX = e.pageX;
offset += newX - startX;
startX = newX;
this.style['-webkit-transform'] = 'translate(' + offset + 'px)';
}
});
I'm seeking advice on how to optimize this code for better performance. Are there any changes or techniques, such as using requestAnimationFrame and adjusting FPS, that could help improve the performance?
UPDATE: How can I enhance the performance of this code, especially in terms of requestAnimationFrame and FPS?
