Haven't checked it with various possibilities, but this may be what you wanted. function myFunction() { var raw = document.getElementById("sara").value; if(raw.length === 10 && raw.indexOf(".") !== -1) { raw = raw.split("."); if(raw.length === 3 && raw[2].length === 4) { var year = parseInt(raw[2]); if(year !== NaN) { document.getElementById("demo").innerHTML = (parseInt(year / 100) + 1); return false; } } } document.getElementById("demo").innerHTML = ""; }
