drag-and-drop

问题 I require the following functionality in my website. Everything has to be done on the client (javascript or any javascript library). I have an image in my local machine, drag and drop it in the browser. Without any request to the server, the javascript has to convert this image as base64.

问题 So I want to make my version of the Battleships game in Angular and to do that I need a 10x10 matrix in which I can drag and drop the ships ( if you played the game you know what I am talking about ) and I'm using the Angular Cdk but I cannot make it work at all. What I have tried so far is make a table out of divs, ships elements aside and drag and drop them on the board but I can't connect the two arrays because the array of ships is not nested and the board is.
