Hi there evajs,
and a warm welcome to these forums.
Here is a very basic example for you to try...
Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<meta name="language" content="english">
<meta http-equiv="Content-Style-Type" content="text/css">
<meta http-equiv="Content-Script-Type" content="text/javascript">
<title></title>
<script type="text/javascript">
if(window.addEventListener){
window.addEventListener('load',multiplication,false);
}
else {
if(window.attachEvent){
window.attachEvent('onload',multiplication);
}
}
function multiplication(){
/* this value may be edited */
multiplier=4;
/****************************/
document.getElementById('m').firstChild.nodeValue='number x '+multiplier+' : ';
document.getElementById('in').onkeyup=function() {
if(isNaN(this.value)) {
alert('Come on, this is not rocket science!!!\n\nJust numbers please.')
this.value='';
document.getElementById('out').value=0;
return;
}
else {
document.getElementById('out').value=this.value*multiplier;
}
}
}
</script>
</head>
<body>
<div>
<label for="in">enter number : </label><input id="in" type="text">
<label id="m" for="out"> </label><input id="out" type="text" value="0" readonly="readonly">
