const board = new Chessboard(document.getElementById("board"), { position: FEN.start, assetsUrl: "../assets/", style: {pieces: {file: "pieces/staunty.svg"}}, extensions: [{class: Markers}] }) board.enableMoveInput(inputHandler) function inputHandler(event) { console.log(event) switch (event.type) { case INPUT_EVENT_TYPE.moveInputStarted: log(`moveInputStarted: ${event.squareFrom}`) return true // false cancels move case INPUT_EVENT_TYPE.validateMoveInput: log(`validateMoveInput: ${event.squareFrom}-${event.squareTo}`) return true // false cancels move case INPUT_EVENT_TYPE.moveInputCanceled: log(`moveInputCanceled`) break case INPUT_EVENT_TYPE.moveInputFinished: log(`moveInputFinished`) break case INPUT_EVENT_TYPE.movingOverSquare: log(`movingOverSquare: ${event.squareTo}`) break } }
