Question

I want to parse a TEXTAREA, putting each line into a JSON array via jQuery. Any idea how to do this?

Answer 1

Just like this:

var array = $('textarea').val().split(/\n|\r/);

So you’ll get JavaScript array object, not JSON string. If you want JSON string you can use jquery-json plugin and then do the following:

var jsonString = $.toJSON( $('textarea').val().split(/\n|\r/) );

And if you want object, not array encoded in JSON do that:

var o = {};
$( $('textarea').val().split(/\n|\r/) ).each(function(i){
   o[i] = this;
});   
var jsonString = $.toJSON(o);
