Example 5.2:
Subtracting
Click this button to see the value in the nProfit variable, the result of subtracting one number from another:
This is the script we used. First we placed this in the HEAD:
<![CDATA[
<SCRIPT LANGUAGE="JAVASCRIPT">
<!--
var nProfit = 0
var nPrice = 99
var nCosts = 47
nProfit = nPrice - nCosts
//-->
</SCRIPT>
]]>
Then we created this button:
<![CDATA[
<form>
<input type="button" name="VariableButton" value="The result of the calculation" onclick="alert(nProfit)">
</form>
]]>
