Hey, working with Jquery and Regex and trying to load a parsed string into an array. So far the Regex works using Expresso. Problem is the Jquery .Split puts a comma between each character anyway. At least the Jqurey .each displays it that way. Unsure if I have a split problem or array write/read problem?

            var words = "my [cell phone] is so [old] its [not cool] anymore"; // Express regex match return

            var arr1 = words.split(new RegExp('\[(\w*\s*)*\]|\w*\s*|\w*'));

            alert(arr1); //m,y, ,[,c,e,l,l, ,p,h,o,n,e,], ,i,s, ,s,o, ,[,o,l,d,], ,i,t,s, ,[,n,o,t, ,c,o,o,l,], ,a,n,y,m,o,r,e

            $.each(arr1, function (index, value) {
                alert(index + ": " + value);  // opens alert over 50 times
            });

Hello. What are you aiming to use this for?
If you access each element in the array and output each element in turn, this will be without the commas. When you access the whole array at once and try to use it as an string, the toString() method is called(except when you use jQuery obviously, see below). This automatically displays the array with each element separated by commas. Don't know if you can override toString() somehow, it wouldn't surprise me. However, it isn't necessary:

Here are some examples - see the link:
http://jsfiddle.net/aL40xbcv/1/

var words = "my [cell phone] is so [old] its [not cool] anymore"; // Express regex match return

var arr1 = words.split(new RegExp('\[(\w*\s*)*\]|\w*\s*|\w*'));

$('#test1').html(arr1.toString());
$('#test2').html(arr1);

$.each(arr1, function (index, value) {
   $('#test3').html($('#test3').html() + " " + index + ": " + value + "<br/>"); 
});

The goal is putting each word into a table using .append(<td><label>'+value+'</td>)

OK - don't know if this is exactly what you wanted, but see the fourth try section of the fiddle below for an example:
http://jsfiddle.net/aL40xbcv/2/

Html:
<table id="ourTable" border="1">
    <tr>
    
    </tr>
</table>

Open in new window


jQuery:
$.each(arr1, function (index, value) {
    $('#ourTable tr:first').append("<td><label>" + value + "</td>"); 
});

Open in new window

I have a working regex using Expresso editor, but it doesn't work the same in js.split. I maybe confusing split and match, thought I could do both as same time.  This regex / match (Expresso):  

Regex: \[(\w*\s?)*\]|(\w*\s?)
Input: qq [ww] ee pp uu [kk pp] pp [dd gg jj] mm
Output:
qq
[ww]
ee
pp
uu
[kk pp]
pp
[dd gg jj]
mm
