Answer 1

Drag'n'Drop with mouse events

Drag’n’Drop is a great interface solution. Taking something, dragging and dropping is a clear and simple way to do many things, from copying and moving (see file managers) to ordering (drop into cart).

In the modern HTML standard there’s a section about Drag Events.

They are interesting, because they allow to solve simple tasks easily, and also allow to handle drag’n’drop of “external” files into the browser. So we can take a file in the OS file-manager and drop it into the browser window. Then JavaScript gains access to its contents.

But native Drag Events also have limitations. For instance, we can limit dragging by a certain area. Also we can’t make it “horizontal” or “vertical” only. There are other drag’n’drop tasks that can’t be implemented using that API.

So here we’ll see how to implement Drag’n’Drop using mouse events. Not that hard either.
