Convert javascript array to string

Question

I'm attempting to loop through a "value" list and convert it to a string. The code is as follows:

var blkstr = $.each(value, function(idx2,val2) {                    
     var str = idx2 + ":" + val2;
     alert(str);
     return str;
}).get().join(", "); 

The alert() method works perfectly and displays the correct value. 

However, jquery's.get() function fails because it does not return the correct kind of object. 

What am I doing incorrectly?
