Javascript: Convert textarea into an array

How would you go 开发者_如何学JAVAabout breaking up a textarea value into an array, based on the end of line separation? Use of jQuery is cool by me...

This should work (tested in Firefox and Google Chrome):

var arrayOfLines = $('#textAreaID').val().split('\n');

Cross-platform way:

var area = document.getElementById("area");             
var lines = area.value.replace(/\r\n/g,"\n").split("\n");

var stringArray = document.getElementById('textarea').value.split('\n');

I like the "cross-platform way" answer best (https://stackoverflow.com/a/32240738/34806) as I've grappled with input from a Mac in the past. Nevertheless I think most of the existing answers could benefit from an additional step.

Specifically, what if some lines are empty? The following will filter out such lines so that we wind up with a "compact" array rather than a "sparse" one (or at least, rather than one with elements containing no values)

var area = document.getElementById("area");             
var lines = area.value.replace(/\r\n/g,"\n").split("\n").filter(line => line);

You could try this function :

function textToArray(){
  var someArray = [];    
  var nameList = $("#txtArea").val();

  $.each(nameList.split(/\n/), function (i, name) {     

      // empty string check
      if(name != ""){

          someArray.push(name);

      }        
});

This method worked well:

var textArea = document.getElementById("textAreaId");
var arrayFromTextArea = textArea.value.split(String.fromCharCode(10));
