Javascript: Convert textarea into an array

问题

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

回答1:

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

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

回答2:

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

回答3:

Cross-platform way:

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

回答4:

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));
