Form math help?! Options

[Maccabee]

Ok here is the code.

<FORM>

F:<INPUT type="text" name="F" value="32"
onChange="C.value = 100/(212-32) * (this.value - 32 )"></td>

C:<INPUT type="text" name="C" value="0"
onChange="F.value = (212-32)/100 * this.value + 32 "></td>

<td colspan="2"><INPUT type="button" value="Click for Answer"></td>

</form>

And here it is in action.

Now if you understand java and stuff youll see how this works.

Now how can I adjust this code for other uses such as determining how many feet there are in how many yards?!

All you have to do is change the onChange Event:

CODE

onChange="yard.value = (this.value / 3 )"

- >

CODE

onChange="feet.value = this.value * 3"

Here is the complete code:

CODE

<table cellpadding="5" cellspacing="0" border="0" >
<form>
<tr>
<td> Feet </td>
<td> <input type="text" name="feet" value="3" onChange="yard.value = (this.value / 3 )" /> </td>
</tr>
<tr>
<td> Yard: </td>
<td> <input type="text" name="yard" value="1" onChange="feet.value = this.value * 3" /> </td>
</tr>
<tr colspan="2" >
<td colspan="2"> <input type="button" value="Click for Answer" /> </td>
</tr>
</form>
</table>
