Example 5.3:
Multiplying
Click this button to see the value in the nArea variable, the result of multiplying numbers:
This is the script we used. First we placed this in the HEAD:
<![CDATA[
<SCRIPT LANGUAGE="JAVASCRIPT">
<!--
var nArea = 0
var nWidth = 100
var nLength = 33
nArea = nWidth * nLength
//-->
</SCRIPT>
]]>
Then we created this button:
<![CDATA[
<form>
<input type="button" name="VariableButton" value="The result of the calculation" onclick="alert(nArea)">
</form>
]]>
