textarea into array javascript

Question

myList contains the following values:

value1
value2
value3

function showArray() {
  var txt = $("#myList").text();
  var textread = txt.split('\n');

  var msg = "";
  for (var i = 0; i < textread .length; i++) {
    msg += i + ": " + textread [i] + "\n";
  }
  alert(msg);
}

my alert gives me the following:

0:value1
value2
value3

It`s not what I wanted and expecting, I was expecting something like:

0: value1
1: value2
2: value3

How can I get the values as expected?

looks like textread.length==1; could you ouput that too and tell the value here ? — marcgg

Have I tweaked your question correctly or does the first alert show all values on one line? — AnthonyWJones

I tried this with a textarea and it pretty much worked.

The only thing I changed was var txt = $("#myList").text(); to var txt = $("#myList").val();.

This works because val() preserves the white space in the textarea, while text() doesn't.

Looks like you have a problem with the character used as line break...
