Javascript String Length Differs From PHP mb_strlen

Question

I use document.getElementById(\"text\").value.length to get the string length through javascript, and mb_strlen($_POST[\'text\']) to get the string

Answer 1

I have found an mb_strlen equivalent function for Javascript, maybe this might be useful for someone else:

function mb_strlen(str) {
    var len = 0;
    for(var i = 0; i < str.length; i++) {
        len += str.charCodeAt(i) < 0 || str.charCodeAt(i) > 255 ? 2 : 1;
    }
    return len;
}

Thanks to all that tried to help!
