How can I merge two arrays in JavaScript to form a table?

Question

How can I merge two arrays in JavaScript to form a table?

I have two sets of data stored in arrays. This is how my information is organized:

var apples = [ "red", "green", "yellow"];
var oranges = [ "sweet", "sour"]

The goal is to create tables with the same number of rows as there are elements in the apple array and the same number of columns as there are elements in the oranges array. This is what has been accomplished thus far:

<html>
<table id = "myfruit">
    <tr>
        <td> Fruits</td>
    </tr>
</table>    
<body>

<script>
var apples = [ "red", "green", "yellow"];
var oranges = [ "sweet", "sour"]
var numberOfRows = apples.length;
var numberOfColumns = oranges.length;

for (var i = 0; i < numberOfRows; i++){
    var column = "<td>" + apples[i] + "</td>";
    for (var j = 0; j < numberOfColumns; j++){
        column += "<td id =" apples.concat(oranges) "></td>;
    }
    $("#myfruit").append("<tr>" + column + "</tr>");
}
</script>
</body>
</html>

However, I am still encountering difficulties in displaying the data accurately.

Answer №1

It appears that there are some errors in the table formatting. The word "table" has been misspelled and a body section is missing.

let cats = ['persian', 'tabby', 'bengal'];
let dogs = ['shepard', 'terria'];


var numberOfRows = cats.length;
var numberOfColumns = dogs.length;

for (var i = 0; i < numberOfRows; i++){
    var row = $("<tr>");
    for (var j = 0; j < numberOfColumns; j++){
        row.append($(`<td>`).text(`${cats[i]} - ${dogs[j]}`));
    }
    $("#mytable tbody").append(row);
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table id = "mytable">
  <tbody>
    <tr>
        <td> Cats/dogs</td>
    </tr>
  </tbody>
</table>

Alternatively, you can utilize the Array.forEach method:

let fruits = [ "apple", "banana", "cherry", "date"];
let colors = [ "red", "yellow", "blue"]

let numFruits = fruits.length;
let numColors = colors.length;

fruits.forEach(function (fruit) {
    $("#mytable").append(`<tr id="${fruit}">`)
  colors.forEach(function (color) {
    $(`#${fruit}`).append(`<td>${fruit},${color}</td>`)
  })
})

To create a dynamic table, you can utilize nested loops in your code. See below for an illustration:

var fruits = [ "apple", "banana", "cherry", "date"];
var colors = [ "red", "yellow", "purple"];

var html = "";
for (var i = 0; i < fruits.length; i++) {
  html += "<tr>";
  for (var j = 0; j < colors.length; j++) {
    html += "<td>";
    html += "fruits[" + i + "] = " + fruits[i] + ", colors[" + j + "] = " + colors[j];
    html += "</td>";
  }
  html += "</tr>";
}
document.getElementById("mydynamictable").innerHTML = html;

<table id="mydynamictable" border="1">
</table>

Welcome to the wonderful world of coding on Stack Overflow! Just a small tweak can make all the difference in your program. Make sure to insert a new tr each time you loop through the outer loop. Have a look at this helpful snippet.

Disclaimer: The code provided may not be perfect, but it gets the job done!

var cats = [ "a", "b", "c", "d", "e", "f"];
var dogs = [ "z", "y", "x", "w"]
var str = '';
for(let cat of cats) {
  str = '<tr>';
  for(let dog of dogs) {
    str += '<td>'+cat+' '+dog+'</td>';
  }
  str += '</tr>';
  $("#mytable").append( str );
}

td {
border: 1px solid #ddd;
padding: 4px 6px;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<tabld id = "mytable">

Answer №5

Your code has some syntax errors that need to be addressed.

Modified HTML:

<table id="pets">
  <tr>
    <td> Cats/dogs</td>
  </tr>
</table>

Adjusted JS: var cats = ["a", "b", "c", "d", "e", "f"]; var dogs = ["z", "y", "x", "w"];

var rows = cats.length;
var columns = dogs.length;

for (var i = 0; i < rows; i++) {
  var rowContent = "<td>" + cats[i] + "</td>";
  for (var j = 0; j < columns; j++) {
    rowContent += "<td></td>";
  }
  $("#pets").append("<tr>" + rowContent + "</tr>");
}
