Pause a for loop
<p>Is it possible to pause a for loop in javascript/jquery?</p>

<p>I have a <code>$.each</code>, that runs through a 63 long array, which have a <code>for</code> inside, which have another <code>for</code>, which have yet another <code>for</code> in it (Makes <code>each</code>><code>for</code>><code>for</code>><code>for</code>), now each  of the <code>for</code> loops through the array, this makes 63^4 (Equals 15752961) different combinations, and that takes time...</p>

<p>Sooo, is it possible to pause it 2sec, at 2k combinations?</p>

<p>Reason why I want to pause the loop, is to unlock the UI...</p>

<p>Code:</p>

<pre><code>var $arr = ["","a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z","A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z","0","1","2","3","4","5","6","7","8","9"],
len = $arr.length,
l = 0,
$("body").delay(1000).show(0, function(){
    $.each($arr, function(index, val){ // 63
        for(var i = 0; i &lt; len; i++){ // 3969
            for(var j = 0; j &lt; len; j++){ // 250047
                for(var k = 0; k &lt; len; k++){ // 15752961
                    thing = val+i+j+k;
                    l++;
                    $("#loading").text(l+"/15752961");
                    console.log(l+"/15752961");
                    $("&lt;div&gt;"+thing+"&lt;/div&gt;&lt;br /&gt;").prependTo("body");                                  
                }
            }
        }
    })
})
</code></pre>

<p>Ps. If someone think, they could clear up my question, please do so :D</p>

<p><strong>/* EDIT */</strong>
If I try to run this server side, I get a server error, both if I use <code>foreach</code> or <code>for</code></p>

<pre><code>$smaa = range("a","z");
$store = range("A","Z");
$tal = range("0","9");
$arr = array_merge($smaa, $store, $tal);

for($i = 0; $i &lt; $count; $i++){ // 62
    for($j = 0; $j &lt; $count; $j++){ // 3844
        for($k = 0; $k &lt; $count; $k++){ // 238328
            for($l = 0; $l &lt; $count; $l++){ // 14776336
                $finish[] = $arr[$i].$arr[$j].$arr[$k].$arr[$l];
            }
            $finish[] = $arr[$i].$arr[$j].$arr[$k];
        }
        $finish[] = $arr[$i].$arr[$j];
    }
$finish[] = $arr[$i];
}

foreach($arr as $first){ // 62
    $finish[] = $first;
    foreach($arr as $second){ // 3844
        $finish[] = $first.$second;
        foreach($arr as $third){ // 238328
            $finish[] = $first.$second.$third;
            foreach($arr as $fourth){ // 14776336
                $finish[] = $first.$second.$third.$fourth;
            }
        }
    }
}
</code></pre>

<p>Please note, that I <strong>don't</strong> use both on the same time</p>
