Question

I have to get the value from a textarea using jQuery and count the number of newlines there. I’d like to do this using a regex-expression. Does anyone know how to do that?

Answer 1

regex does not have count. better use array like this

var val = textarea.value;
var arr = val.split(/[\n\r]/g);
var count = arr.length;

you could condense this in less rows and vars…

var count = $('textarea').val().split(/[\n\r]/g).length;
