sollte mal ein Input Feld basteln was die Zahl richtig formatiert.
Vielleicht kann es jemand gebrauchen.
Code:
<!doctype html>
<head>
<title>Input</title>
<style type="text/css">
input.right{
text-align:right;
}
</style>
<script type="text/javascript">
function addCommas(event, element){
var keyCode = ('which' in event) ? event.which : event.keyCode;
if (keyCode == 8 || keyCode == 46 || keyCode == 37 || keyCode == 39 || keyCode == 46){
return true;
}
if ((keyCode < 48 || keyCode > 57)) {
return false;
}
if ( element.value.length >= 2 ) {
var buffer = element.value.replace(",","") + String.fromCharCode(keyCode);
var buffer = buffer.replace(/\./g, '');
var fixed = buffer.slice(0, -2) +","+buffer.slice(-2)
var number = fixed.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ".");
element.value = number;
}else if( element.value.length <= 1) {
element.value = element.value + String.fromCharCode(keyCode);
}
return false;
}
</script>
</head>
<body>
<form action="#">
<p>Betrag:<br><input name="number" id="number" class="right" type="text" size="40" onkeydown="return addCommas(event, this)" /></p>
<p><input type="reset" value="Reset" /></p>
</form>
<br/>
1<br/>10<br/>1,00<br/>10,00<br/>100,00<br/>1.000,00<br/>10.000,00<br/>100.000,00<br/>1.000.000,00<br/>
</body>
</html>
