Remove the last "\n" from a textarea
Only remove the last newline characters (\n
):
verses1 = "1\n222\n"verses1.replace(/\n$/, "")// "1\n222"verses2 = "1\n222\n\n"verses2.replace(/\n$/, "")// "1\n222\n"
Only all the last newlines (\n
):
verses = "1\n222\n\n"verses.replace(/\n+$/, "")// "1\n222"
from http://en.wikipedia.org/wiki/Trim_%28programming%29
String.prototype.trim = function() { return this.replace(/^\s+|\s+$/g, "");};
That will add a trim function to string variables that will remove whitespace from the beginning and end of a string.
With this you can do stuff like:
var mystr = "this is my string "; // including newlinesmystr = mystr.trim();
$.trim() should do the trick!
It trims whitespace and newline characters from the beginning and ending of the specified string.
