我试图用html/css/js绘制一个围棋棋盘,但我想不出一个好的方法。这是我所做的:
#Board {position: relative; left:100; top:100; height:570; width:570;}
.Square {position: absolute; height:30; width:30; background-color:#DCB579; border-color: black; border-width: 1; border-style: solid;}
.lineh0{top:0;}
.lineh1{top:30;}
.lineh2{top:60;}
.lineh3{top:90;}
.lineh4{top:120;}
.lineh5{top:150;}
.lineh6{top:180;}
.
.
.lineh18{top:540;}
.linev0{left:0;}
.linev1{left:30;}
.linev2{left:60;}
.linev3{left:90;}
.linev4{left:120;}
.linev5{left:150;}
.linev6{left:180;}
.
.
.linev18{left:540;}
我用它们在棋盘上画正方形的方法是,我用Square
类和lineh
和linev
类在Board
元素中创建元素,这取决于正方形的位置。例如,左上角和右下角的正方形:
<div id="Board">
<div class="Square lineh0 linev0"></div>
<div class="Square lineh18 linev18"></div>
</div>
问题是围棋棋盘上有361个方块,手工输入它们并不是一种好的技巧。我的问题是什么是更好的方法?

我会这样做:
let board = document.getElementById("Board");
// each lines
for(let i = 0; i < 19; i++) {
// each column
for(let j = 0; j < 19; j++) {
// create a square
let square = document.createElement("div");
// add the Square class
square.classList.add("Square");
// instead of class linehx
square.style.top = 30 * i + "px";
// or use : square.classList.add("lineh" + i);
// instead of class linevx
square.style.left = 30 * j + "px";
// or use : square.classList.add("linev" + j);
// add it to the board
board.appendChild(square);
}
}
.Square {
position: absolute;
height:30;
width:30;
background-color:#DCB579;
border-color: black;
border-width: 1;
border-style: solid;
}
<div id="Board">
</div>
可能需要修改您的Square样式以获得更好的结果

我会使用flex和flex-wrap,这样你就不必单独定位每个方块了。
#board {
width: 570px;
height: 570px;
display: flex;
flex-direction: row;
flex-wrap: wrap;
justify-content: flex-start;
align-items: flex-start;
}
.square {
width: 30px;
height: 30px;
}
/* below styles for demo only */
.square:nth-child(odd) {
background: grey;
}
.square:nth-child(even) {
background: lightgrey;
}
<div id="board">
