Split string in JavaScript and detect line break

Solution 1:

Use the following:

var enteredText = document.getElementById("textArea").value;
var numberOfLineBreaks = (enteredText.match(/\n/g)||[]).length;
alert('Number of breaks: ' + numberOfLineBreaks);

DEMO

Now what I did was to split the string first using linebreaks, and then split it again like you did before. Note: you can also use jQuery combined with regex for this:

var splitted = $('#textArea').val().split("\n");           // will split on line breaks

Hope that helps you out!

Solution 2:

Split string in JavaScript

var array = str.match(/[^\r\n]+/g);

OR
