Question

我有一个有关根据正在使用的窗口或浏览器的大小调整/绘制游戏板大小的问题。我正在使用html / css / js对游戏黑白棋进行编码。我要实现的图像将被附加。游戏板本身的高度与其右侧显示的信息相同。我希望它是例如窗口高度的70％，这样我仍然有30％的空间用于制作边框等。在HTML中，我用'board-table'ID定义了一个表，然后尝试制作一个变量'大小'确定此桌子的高度。在CSS中，我指定高度应为70％，以便以后可以绘制游戏板。但是，当我以不同的尺寸重新加载页面时，它总是有前缀的大小，因此我想知道如何解决它。我的代码部分显示在下面。

HTML：

<table id="board-table"></table>

CSS：

#board-table {
  height: 70%;
}

Javascript：

function draw() {
  var size = $('#board-table').height();
  var square = (1/8) * size;
  var half = (1/2) * square;
  for (var y = 0; y < 8; y++) {
    for (var x = 0; x < 8; x++) {
      var canvas = $("#canv_" + x + "" + y)[0]
      var ctx = canvas.getContext("2d")
      if (game.board[x][y] == 1) {
        ctx.fillStyle = "green"
        ctx.fillRect(0, 0, square, square)
        ctx.beginPath()
        ctx.fillStyle = "white"
        ctx.arc(half, half, half, 0, 2 * Math.PI)
        ctx.fill()
      } else if (game.board[x][y] == 2) {
        ctx.fillStyle = "green"
        ctx.fillRect(0, 0, square, square)
        ctx.beginPath()
        ctx.fillStyle = "black"
        ctx.arc(half, half, half, 0, 2 * Math.PI)
        ctx.fill()
      } else {
        ctx.fillStyle = "green"
        ctx.fillRect(0, 0, square, square)
      }
    }
  }
}

function generateBoard() {
  for (var y = 0; y < 8; y++) {
    $("#board-table").append("<tr id=row" + y + "" + "><tr")
    for (var x = 0; x < 8; x++) {
      $("#row" + y).append("<td id=cell_" + x + "" + y + "></td>")
      $("#cell_" + x + "" + y).append("<canvas height=100% onclick=handleclick(" + x + "," + y + ") onmouseover=handlehover(" + x + "," + y + ") width =100% id=canv_" + x + "" + y + "></canvas>")
    }
  }
}

Example of what I am trying to achieve.

Answer 1

在CSS中，当您使用height: 70%;时，它指的是包含元素的70％。

这可以通过使用height: 70vh;

这是我的代码，与您的代码有很大不同，但是它可以缩放并处理放置的零件和放置的零件的颜色。
