jquery - Convert javascript array to string

Question

I'm trying to iterate over a "value" list and convert it into a string. Here is the code:

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

alert() function works just fine and displays the proper value. But somehow, jquery's .get() function doesn't get the right sort of object and fails. What am I doing wrong?

Answer 1

If value is not a plain array, such code will work fine:

var value = { "aaa": "111", "bbb": "222", "ccc": "333" };
var blkstr = [];
$.each(value, function(idx2,val2) {                    
  var str = idx2 + ":" + val2;
  blkstr.push(str);
});
console.log(blkstr.join(", "));
