In this JavaScript tool for counting characters, every carriage return is counted as two characters

Hello there! I have created a character counter in JavaScript that looks like this:

<textarea class="SmsText" id="txttemplate"  maxlength="160" />
<span id="charsCount">160</span></strong><span>character(s) left</span>
$(document).ready(function() {
        keypressed = false;
        $('#txttemplate').keypress(function (e) {
            keypressed = true;
        });

        $('#txttemplate').keyup(function () {
            counter($(this));
        });

        $('#txttemplate').keydown(function () {
            counter($(this));
        });

    });
function counter(obj) {
        var max = obj.attr('maxlength');
        var valLen = obj.val().length;
        obj.val(obj.val().substring(0, max));
        $('#charsCount').text(max - valLen);
    }

Currently, my code treats the "enter" key (13) as a single character, while the maxlength attribute of the textarea counts it as 2 characters. How can I modify my code to count two characters when "enter" or "carriage return" is pressed?

Answer №1

If you want to track the keys pressed and increase a counter based on it, you can utilize the key pressed event argument to achieve this

$('#txttemplate').on("keypress", function (e) {
    if (e.keyCode == 13) {
        // Add your code here to increment the counter
    } 
}
