Crear una cuadrícula de 16x16 usando JavaScript




html css (3)

Estoy tratando de crear una cuadrícula de 16x16 en JavaScript. El método que estoy tratando de usar es crear un div vacío en HTML, y luego agregarle otros div y delinear sus bordes. Parece que no puedo hacer que esto funcione, y he puesto mi código a continuación.

HTML:

<!DOCTYPE html>

<head>
    <title>Etch-a-Sketch</title>
    <link rel="stylesheet" type="text/css" href="style.css">
    <script type="text/javascript" src="app.js"></script>
</head>

<body>
    <div id="container">
    </div>

</body>

JavaScript:

// Sets important constants and variables

const container = document.getElementById("container");
let rows = document.getElementsByClassName("gridRow");
let cells = document.getElementsByClassName("cell");

// Creates a default grid sized 16x16
function defaultGrid() {
    makeRows(16);
    makeColumns(16);
}

// Takes (rows, columns) input and makes a grid
function makeRows(rowNum) {

    // Creates rows
    for (r = 0; r < rowNum; r++) {
        let row = document.createElement("div");
        container.appendChild(row).className = "gridRow";
    };
};

// Creates columns
function makeColumns(cellNum) {
    for (i = 0; i < rows.length; i++) {
        for (j = 0; j < cellNum; j++) {
            let newCell = document.createElement("div");
            rows[j].appendChild(newCell).className = "cell";
        };

    };
};

CSS:

.gridRow {
    border: 1px solid black;
}

.cell {
    border: 1px solid black;
}

CÓDIGO HTML

<html>
<head>
    <link rel=stylesheet type="text/css" href="Project_Javascript_jQuery.css">
    <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
    <script type="text/javascript" src="Project_Javascript_jQuery.js"></script>

<center><button class="newGrid">New Grid</button></center>

<div id="container"></div>

</body>

</html>

CSS

 #container {
    position: relative;
    top: 30px;
    outline: 2px solid #000;
    font-size: 0;
    margin: auto;
    height: 960px;
    width: 960px;
    padding: 0;
    border: none;
}

.grid {
    margin: 0;
    padding: 0;
    border: none;
    outline: 1px solid #000;
    display: inline-block;
}

JavaScript

// Function that builds a grid in the "container"
function createGrid(x) {
    for (var rows = 0; rows < x; rows++) {
        for (var columns = 0; columns < x; columns++) {
            $("#container").append("<div class='grid'></div>");
        };
    };
    $(".grid").width(960/x);
    $(".grid").height(960/x);
};

// Function that clears the grid
function clearGrid(){
    $(".grid").remove();
};

// Function that prompts the user to select the number of boxes in a new grid
// the function then also creates that new grid
function refreshGrid(){
    var z = prompt("How many boxes per side?");
    clearGrid();
    createGrid(z);
};

// Create a 16x16 grid when the page loads.
// Creates a hover effect that changes the color of a square to black when the mouse passes over it, leaving a (pixel) trail through the grid
// allows the click of a button to prompt the user to create a new grid
$(document).ready(function() {
    createGrid(16);

    $(".grid").mouseover(function() {
        $(this).css("background-color", "black");
        });

    $(".newGrid").click(function() {
        refreshGrid();

        $(".grid").mouseover(function() {
        $(this).css("background-color", "black");
        });
    });
});

La solución, según lo provisto por Gerardo Furtado es cambiar el CSS.

CSS antiguo:

.gridRow {
    border: 1px solid black;
}

.cell {
    border: 1px solid black;
}

CSS fijo:

.cell {
  border: 1px solid gray;
  min-width: 10px;
  min-height: 20px;
  display: inline-block;
}

Tratar

let n=16, s='';

for(let i=0; i<n; i++) {
  s+= '<div class="row">'
  for(let j=0; j<n; j++) s+= `<div class="cell"> ${(i*n+j).toString(16)} </div>`;
  s+= '</div>'
}

container.innerHTML = s;
.row { display: flex; font-size: 9.5px; text-align: center; color: red }
.cell { width: 10px; height: 10px; margin: 1px; border: 1px solid black;}
<div id="container"></div>
