If you "right click" and view source of this page you
will see that we have the following JavaScript function within the page which is able to act upon the three tables, "c1",
"c2" and "c3".
<SCRIPT LANGUAGE="javascript">
var table='c1';
function combo(table) {
if (table=='c1') {
if (document.all.c1.style.visibility=="hidden") {
document.all.c1.style.visibility="visible";
}
else {document.all.c1.style.visibility="hidden";}
}
if (table=='c2') {
if (document.all.c2.style.visibility=="hidden") {
document.all.c2.style.visibility="visible";
}
else {document.all.c2.style.visibility="hidden";}
}
if (table=='c3') {
if (document.all.c3.style.visibility=="hidden") {
document.all.c3.style.visibility="visible";
}
else {document.all.c3.style.visibility="hidden";}
}
}
</script>
In the bardatajs.txt ( click here to
view ) file you will see that each of our data elements has the word "javascript" entered in the target field and
the JavaScript function name with the relevant value entered in the URL field.
