 * @param string textarea
 * @param int maxLength
 * @param string div
 */
function charsRemain(textarea, maxLength, div) {
	var currentLength = $(textarea).val().length;
 
	var charsLeft = maxLength - currentLength;
	if (charsLeft < 0) { charsLeft = 0; }
 
	$("#"+ div +"_charsRemain").html(charsLeft);
 
	if (currentLength > maxLength) {
		var fullText = $(textarea).val().substring(0, maxLength);
		$(textarea).val(fullText);
	}
}
