Question

我有一个带有自定义模板的“Chess”页面。当我在线使用cheessboard.js脚本时没有问题。当我想使用它的下载版本并将<base href="http://chessboardjs.com/" />替换为本地路径时，它会在浏览器上产生此错误：

GET http://localhost/css/chessboard.css  (index):4
GET http://localhost/js/chess.js  (index):8
GET http://localhost/js/jquery-1.10.1.min.js  (index):9
GET http://localhost/js/chessboard.js  (index):10
Uncaught ReferenceError: $ is not defined

如何调整模板Chess.php？

                var possibleMoves = game.moves();
                if (game.game_over() === true || game.in_draw() === true || possibleMoves.length === 0) return;
                var randomIndex = Math.floor(Math.random() * possibleMoves.length);
                game.move(possibleMoves[randomIndex]);
                board.position(game.fen());
                window.setTimeout(makeRandomMove, 500);
            };
            board = new ChessBoard('board', 'start');
            window.setTimeout(makeRandomMove, 500);

<base>属性specifies the base URL to use for all relative URLs contained within a document。而且您可能会将文件放在主题目录中，我们可以使用get_stylesheet_directory_uri()。

正确的是使用wp_enqueue_scripts加载JS和CSS文件，并且只在需要它们的页面上执行。此外，不要从外部来源排队外部jQuery，使用与WP捆绑的那个：wp_enqueue_script('jquery');。

你也可以create a shortcode。以下只是目录/wp-content/themes/your-theme/chessboardjs/中Chessboardjs文件的原始示例。模板page-chess.php就是这样：

<?php
/**
 * Template Name: Chess
 */
$base = get_stylesheet_directory_uri() . '/chessboardjs';
?><html>
<head>
    <link rel="stylesheet" href="<?php echo $base; ?>/css/chessboard-0.3.0.min.css" />
    <script src="<?php echo $base; ?>/js/chess.js"></script>
    <script src="//cdnjs.cloudflare.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
    <script src="<?php echo $base; ?>/js/chessboard-0.3.0.min.js"></script>
</head>
<body>
    <div id="board" style="width: 400px"></div>
    <script>
        var init = function() {
            var board, game = new Chess();
            var makeRandomMove = function() {
                var possibleMoves = game.moves();
                if (game.game_over() === true || game.in_draw() === true || possibleMoves.length === 0) return;
                var randomIndex = Math.floor(Math.random() * possibleMoves.length);
                game.move(possibleMoves[randomIndex]);
                board.position(game.fen());
                window.setTimeout(makeRandomMove, 500);
            };
            var cfg = {
              pieceTheme: '<?php echo $base; ?>/img/chesspieces/wikipedia/{piece}.png',
              position: 'start'
            };
            board = new ChessBoard('board', cfg);
            window.setTimeout(makeRandomMove, 500);
        };
        jQuery(document).ready(init);
    </script>
</body>
</html>
