var planets = [

Sort two dimensional array

<head> <title>Array literal</title> <script type="text/javascript" >
function compare(a, b) {
return a[1] - b[1];
} var planets = [
["A", 0.3], ["B", 0.9], ["C", 1], ["D", 0.8], ["E", 2.4] ];
planets.sort(compare);
document.write(planets);

Use nested for loop to loop through the two-dimension array

<head> <title>Array literal</title> <script type="text/javascript" >
var planets = new Array(
new Array("A", "B", "C"),
new Array("D", "E", "F")
);
for (var i = 0; i < planets.length; i++) {
for (var j = 0; j < planets[i].length; j++)
{
document.write("planets[" + i + "][" + j + "] = " + planets[i][j]);
document.write("
");
}
}

Use two-dimensional array to store matrix data
<source lang="html4strict">
<html>
<head> <title>Array literal</title> <script type="text/javascript" >
var planets = [
[1, "K", "F", "M", "1:45"], [2, "N", "G", "M", "3.8"], [3, "M", "A", "W", "8.4"], [4, "F", "S", "R", "6.4"], [5, "J", "C", "M", "6.6"] ];
for (var i = 0; i < planets.length; i++) {
for (var j = 0; j < planets[i].length; j++)
{
document.write("planets[" + i + "][" + j + "] = " + planets[i][j]);
document.write("
");
}
}
