Percentage Calculator

Hi Everyone
I am thinking about using the Percentage Calculator
http://www.javascriptkit.com/script/script2/percentage.shtml

<SCRIPT language=JavaScript>

function perc1() {
a = document.form1.a.value/100;
b = a*document.form1.b.value;
document.form1.total1.value = b
}
function perc2() {
a = document.form1.c.value;
b = document.form1.d.value;
c = a/b;
d = c*100;
document.form1.total2.value = d
}
//-->
</SCRIPT>

<FORM name=form1>
<TABLE cellSpacing=1 cellPadding=1 border=1>
<TBODY>
<TR>
<TD align=middle colSpan=3><B><FONT size=4>Percentage Calculator</FONT></B>
</TD>
<TR>
<TD>What is <INPUT size=5 name=a> % of <INPUT size=5 name=b>?</TD>
<TD>Answer: <INPUT maxLength=40 size=5 name=total1></TD>
<TD><INPUT onclick=perc1() type=button value=Calculate></TD>
<TR>
<TD><INPUT size=5 name=c> is what percent of <INPUT size=5
name=d>?</TD>
<TD>Answer: <INPUT size=5 name=total2> %</TD>
<TD><INPUT onclick=perc2() type=button value=Calculate></TD>
<TR>
<TD align=middle
colSpan=3><INPUT type=reset value=Reset></TD></TR></TBODY></TABLE></FORM>
Is there any way to add a drop down value menu instead of typing in the numbers ?
Been a bit of a head scratcher for me so far :rolleyes:


Donna

You can always do that but do you only want whole numbers and up to what number in each field?

This will show you how you can go about it.

<FORM name=form1>
<TABLE cellSpacing=1 cellPadding=1 border=1>
<TBODY>
<TR>
<TD align=middle colSpan=3><B><FONT size=4>Percentage Calculator</FONT></B>
</TD>
<TR>
<TD>What is
<script language="javascript">
document.write("<select name=a>");
var i=1;
for (i=1;i<=100;i++)
{
document.write("<option value="+i+">"+i+"</option>");
}
</script>
</select>
% of <INPUT size=5 name=b>?</TD>

Sorry should have been more clear :thumbsup:
I am trying to figure out how to add a text drop down menu and the number which is associated to the text.
Does that make sense :confused:

You will have fun doing the arrays if this is what you want.

<TD>What is
<script language="javascript">
var iNumber=["Zero","One","Two","Three","Four","Five","Six","Seven","Eight","Nine","Ten"];
document.write("<select name=a>");
var i=0;
for (i=0;i<=10;i++)
{
document.write("<option value="+i+">"+iNumber[i]+"</option>");
}
</script>
</select>
% of <INPUT size=5 name=b>?</TD>

I am going to be a pain here...
Not quite what I had in mind ( but very close ), but you do your your stuff jimhill:thumbsup:
I would like something like this added..

<option value=2926>************text**********</option>

So the idea is to replace both boxes with this drop down menu style to give a overall percentage.
