Example 4.3:
Undefined Variables
Click on the button to see what happens when you use text2, an undefined variable:
This is the script we used. First, we put this in the HEAD:
<![CDATA[
<SCRIPT LANGUAGE="JAVASCRIPT">
<!--
var text2
//-->
</SCRIPT>
]]>
Then we created this button:
<![CDATA[
<form>
<input type="button" value="Undefined variable, text2" onclick=alert(text2)>
</form>
]]>
