jquery char into - convert textareas string value to JavaScript array separated by new lines

2 Answers

Use split function:

var arrayOfLines = $("#input").val().split("\n");
from split

I have a textarea where the user can write up to 1000 characters. I need to get the jQuery('#textarea').val() and create an array where each item is a line of the textarea's value. That means:

This is a nice line inside the textarea.
This is another line.
(let's asume this line is empty - it should be ignored).
Someone left more than 2 new lines above.

Should be converted to a JavaScript array:

var texts = [];
text[0] = 'This is a nice line inside the textarea.';
text[1] = 'This is another line.';
text[2] = 'Someone left more than 2 new lines above.';

That way they can be easily imploded for to querystring (this is the qs format required by the provider):

example.com/process.php?q=["This is a nice line inside the textarea.","This is another line.","Someone left more than 2 new lines above."]

I tried both the phpjs explode() and string.split("\n") approaches but they doesn't take care of the extra new lines (aka line breakes). Any ideas?

Try this

var lines = [];
$.each($('textarea').val().split(/\n/), function(i, line){
   if(line && line.length){
