jquery multidimensional array shuffle random
<p>I want to minimize my code from:</p>

<pre><code>myArrayA = [1, 2, 3, 4, 5];
fisherYates(myArrayA);
myArrayB = [6, 7, 8, 9, 10];
fisherYates(myArrayB);
myArrayC = [11, 12, 13, 14, 15];
fisherYates(myArrayC);
myArrayD = [16, 17, 18, 19, 20];
fisherYates(myArrayD);
myArrayE = [21, 22, 23, 24, 25];
fisherYates(myArrayE);
</code></pre>

<p>To:</p>

<pre><code>var multArr = [[1, 2, 3, 4, 5], [6, 7, 8, 9, 10], [11, 12, 13, 14, 15], [16, 17, 18, 19, 20], [21, 22, 23, 24, 25]];
fisherYates(multArr);
</code></pre>

<p>The output I want is like this:</p>

<pre><code>[4,2,3,5,1],[7,10,6,9,8],[11,15,12,14,13],[18,17,16,20,19],[22,21,25,23,24]
</code></pre>

<p>I tried this code:<br/>
<a href="http://jsfiddle.net/arrow/yFn8U/" rel="nofollow">http://jsfiddle.net/arrow/yFn8U/</a><br/></p>

<pre><code>function fisherYates(myArray) {
var i = myArray.length, j, tempi, tempj;
if (i === 0) return false;
while (--i) {
    j = Math.floor(Math.random() * (i + 1));
    tempi = myArray[i];
    tempj = myArray[j];
    myArray[i] = tempj;
    myArray[j] = tempi;
}
}
var multArr = [[1, 2, 3, 4, 5], [6, 7, 8, 9, 10], [11, 12, 13, 14, 15], [16, 17, 18, 19, 20], [21, 22, 23, 24, 25]];
fisherYates(multArr);
</code></pre>

<p>But my code only randomizes the order of the chunks not the values in each chunk.<br/>
The output I want is like this:</p>

<pre><code>[4,2,3,5,1],[7,10,6,9,8],[11,15,12,14,13],[18,17,16,20,19],[22,21,25,23,24]
</code></pre>

<p>I want each chunk inside the array to be in the same order but each chunk must be randomized.<br/>
Is there a way to do this with jQuery?<br/>
I also wonder how to get values from the shuffled/randomized array?<br/>
At the moment I get the values like this:</p>

<pre><code>myArrayA[i]
myArrayB[i]
myArrayC[i]
myArrayD[i]
myArrayE[i]
</code></pre>

<p>I would guess I will get them with something like:</p>

<pre><code>multArr [[0][i]];
multArr [[1][i]];
multArr [[2][i]];
multArr [[3][i]];
multArr [[4][i]];
</code></pre>

<p>Finally I wonder if minimizing the code will give better performance?</p>
