I am dumb at this kind of stuff.

dFliter.js is below

var dFilterStep

function dFilterStrip (dFilterTemp, dFilterMask)
{
dFilterMask = replace(dFilterMask,'#','');
for (dFilterStep = 0; dFilterStep < dFilterMask.length++; dFilterStep++)
{
dFilterTemp =
replace(dFilterTemp,dFilterMask.substring(dFilterStep,dFilterStep+1),'');
}
return dFilterTemp;
}

function dFilterMax (dFilterMask)
{
dFilterTemp = dFilterMask;
for (dFilterStep = 0; dFilterStep < (dFilterMask.length+1);
dFilterStep++)
{
if (dFilterMask.charAt(dFilterStep)!='#')
{
dFilterTemp =
replace(dFilterTemp,dFilterMask.charAt(dFilterStep),'');
}
}
return dFilterTemp.length;
}

function dFilter (key, textbox, dFilterMask)
{
dFilterNum = dFilterStrip(textbox.value, dFilterMask+"_");
if (key>95&&key<106){key -= 48}

if (key==9)
{
return true;
}
else if (key==8&&dFilterNum.length!=0)
{
dFilterNum = dFilterNum.substring(0,dFilterNum.length-1);
}
else if ( ((key>47&&key<58)))
{
dFilterNum=dFilterNum+String.fromCharCode(key);
}

var dFilterFinal='';

for (dFilterStep = 0; dFilterStep < dFilterMask.length; dFilterStep++)
{
if (dFilterMask.charAt(dFilterStep)=='#')
{
if (dFilterNum.length!=0)
{
dFilterFinal = dFilterFinal + dFilterNum.charAt(0);
dFilterNum = dFilterNum.substring(1,dFilterNum.length);
}
else
{
dFilterFinal = dFilterFinal + "_";
}
}
else if (dFilterMask.charAt(dFilterStep)!='#')
{
dFilterFinal = dFilterFinal + dFilterMask.charAt(dFilterStep);
}
// dFilterTemp =
replace(dFilterTemp,dFilterMask.substring(dFilterStep,dFilterStep+1),'');
}


textbox.value = dFilterFinal;
return false;
}

function replace(fullString,text,by) {
// Replaces text with by in string
var strLength = fullString.length, txtLength = text.length;
if ((strLength == 0) || (txtLength == 0)) return fullString;

var i = fullString.indexOf(text);
if ((!i) && (text != fullString.substring(0,txtLength))) return
fullString;
if (i == -1) return fullString;

var newstr = fullString.substring(0,i) + by;

if (i+txtLength < strLength)
newstr +=
replace(fullString.substring(i+txtLength,strLength),text,by);

return newstr;
}

Thanks for your help in advance
