Multi-Dimensional Array

Copy linkTweet thisAlerts:
Jan 18.2013

I have an array, called, “myArray”. Inside this myArray are 4 more arrays, “m0, m1, m2, m3”.
How do I access all the elements in all the array?

Here’s my code, :

[CODE]<!DOCTYPE html>
<html>
<head>
<title></title>
</head>

<body>
<script>
var m0 = [0, 1, 2, 3, 4];
var m1 = [5, 6, 7, 8, 9];
var m2 = [10, 11, 12, 13, 14];
var m3 = [15, 16, 17, 18, 19];

var myArray = [m0, m1, m2, m3];

for (var i = 0; i < myArray.length; i++) {
for (var j = 0; j < (“m”+i).length; j++) {
document.writeln(myArray[i][j]);
}
}
</script>
</body>
</html>[/CODE]

This code only give me the first 2 elements in each array.
But, I would like to get all the elements in all the arrays.

tks

Why bother with the entire 'jquery' library for this: $('div').html(result);

when all you needed to change was this
<i>
</i>&lt;!DOCTYPE HTML&gt;
&lt;html&gt;
&lt;head&gt;
&lt;meta http-equiv="Content-Type" content="text/html; charset=utf-8"&gt;
&lt;title&gt;JS Bin&lt;/title&gt;
&lt;/head&gt;

&lt;body&gt;
&lt;div id="divBox"&gt;&lt;/div&gt;

&lt;script type="text/javascript"&gt;
var m0 = [0, 1, 2, 3, 4];
var m1 = [5, 6, 7, 8, 9];
var m2 = [10, 11, 12, 13, 14];
var m3 = [15, 16, 17, 18, 19];

var myArray = m0.concat(m1,m2,m3);
document.getElementById('divBox').innerHTML = myArray;
&lt;/script&gt;

&lt;/body&gt;
&lt;/html&gt;
