The Javascript Smart Marketing Toolkit

Javascript banner ad and promotional content cycling toolkit

This is part of the Javascript Smart Marketing Toolkit.

Using the toolkit, it is possible for you to manage your banner adverts and local storage (roughly speaking, equivalent to cookies) without having to do any detailed programming yourself. Once you've edited your banner details into the toolkit (see the remarks in the toolkit code for where to do this), you can use these lines of code to have your adverts automatically cycled:

<div id="banner"></div>
<script>document.querySelector("#banner").innerHTML = output_banner(least_views())</script>

Although this code was originally developed when banner adverts were all the rage (!), it can also be used for cycling other promotional content within your website.


Here's an example of this code in action. When you revisit this page, you'll see the next ad in this slot. I've also added the banner code at the foot of the other demonstration pages. Whatever order you visit the demonstration pages in, the adverts will cycle in the right order.

Documentation for content cycling functions

Table explaining banner advert functions of the toolkit
Function What it does
set_up() The set_up() routine must be run when the page loads.
output_banner(number) After the hard work of editing the set_up() routine, all you need to do to display a banner advert (and automatically keep track of how many times it's been displayed) is to call this routine with the appropriate banner number. You'll need to wrap this is a document.write() or use the more elegant example code above.
least_views() This will tell you the number of the banner advert that has been shown the fewest times.
