JS+CSS绘制棋盘格的示例代码

在这篇文章中，我将展示如何使用 css 和一些 JavaScript 来设计棋盘。

为此，你需要对 CSS Flex-box 和 nth-child() 属性有基本的了解。

所以让我们开始吧......

实现思路

我们将为每个偶数行添加 containerEven 类作为父容器，为每个奇数行添加 containerOdd，

下面显示了相同的 CSS

.containerEven>div:nth-child(odd) {
    background-color: white;
}

.containerEven>div:nth-child(even) {
    background-color: black;
}

.containerOdd>div:nth-child(odd) {
    background-color: black;
}

.containerOdd>div:nth-child(even) {
    background-color: white;
}

这是html部分

<div class="parent-class">
    <section class="containerEven" id='container1'></section>
    <section class="containerOdd" id='container2'></section>
    <section class="containerEven" id='container3'></section>
    <section class="containerOdd" id='container4'></section>
    <section class="containerEven" id='container5'></section>
    <section class="containerOdd" id='container6'></section>
    <section class="containerEven" id='container7'></section>
    <section class="containerOdd" id='container8'></section>
</div>

现在剩下的就是使用 javascript 在相应的 id 的帮助下在这些部分标签内动态附加元素。

 var res1 = [], res2 = [], res3 = [], res4 = [], res5 = [], res6 = [], res7 = [], res8 = [];
    for (i = 1; i <= 8; i++) {
        res1 += `<div class="item"></div>`
        res2 += `<div class="item"></div>`
        res3 += `<div class="item"></div>`
        res4 += `<div class="item"></div>`
        res5 += `<div class="item"></div>`
        res6 += `<div class="item"></div>`
        res7 += `<div class="item"></div>`
        res8 += `<div class="item"></div>`
    }
    document.getElementById(`container1`).innerHTML = res1;
    document.getElementById(`container2`).innerHTML = res2;
    document.getElementById(`container3`).innerHTML = res3;
    document.getElementById(`container4`).innerHTML = res4;
    document.getElementById(`container5`).innerHTML = res5;
    document.getElementById(`container6`).innerHTML = res6;
    document.getElementById(`container7`).innerHTML = res7;
    document.getElementById(`container8`).innerHTML = res8;

在这里我们所做的是使用 8 个数组来存储每一行​​数据。当我们得到数据再将其附加到相应的容器 id，

下面是带有输出的完整代码

<style>
    .parent-class {
        border: 5px chocolate groove;
    }

    .containerEven,
    .containerOdd {
        display: flex;
        background-color: dodgerblue;
    }

    .item {
        background-color: #f1f1f1;
        padding: 20px;
        font-size: 30px;
        flex: 1;
        height: 50px;
        text-align: center;
    }

    .containerEven>div:nth-child(odd) {
        background-color: white;
    }

    .containerEven>div:nth-child(even) {
        background-color: black;
    }

    .containerOdd>div:nth-child(odd) {
        background-color: black;
    }

    .containerOdd>div:nth-child(even) {
        background-color: white;
    }
</style>

<div class="parent-class">
    <section class="containerEven" id='container1'></section>
    <section class="containerOdd" id='container2'></section>
    <section class="containerEven" id='container3'></section>
    <section class="containerOdd" id='container4'></section>
    <section class="containerEven" id='container5'></section>
    <section class="containerOdd" id='container6'></section>
    <section class="containerEven" id='container7'></section>
    <section class="containerOdd" id='container8'></section>
</div>

<script>
    var res1 = [], res2 = [], res3 = [], res4 = [], res5 = [], res6 = [], res7 = [], res8 = [];
    for (i = 1; i <= 8; i++) {
        res1 += `<div class="item"></div>`
        res2 += `<div class="item"></div>`
        res3 += `<div class="item"></div>`
        res4 += `<div class="item"></div>`
        res5 += `<div class="item"></div>`
        res6 += `<div class="item"></div>`
        res7 += `<div class="item"></div>`
        res8 += `<div class="item"></div>`
    }
    document.getElementById(`container1`).innerHTML = res1;
    document.getElementById(`container2`).innerHTML = res2;
    document.getElementById(`container3`).innerHTML = res3;
    document.getElementById(`container4`).innerHTML = res4;
    document.getElementById(`container5`).innerHTML = res5;
    document.getElementById(`container6`).innerHTML = res6;
    document.getElementById(`container7`).innerHTML = res7;
    document.getElementById(`container8`).innerHTML = res8;
</script>
