JavaScript libraries

JavaScript libraries are loaded in the following ways when Digital Data Exchange evaluates website pages.

After the unique page identifier is found on a website page, page group and tag rules are run in the order in which they were deployed in Digital Data Exchange.

If page group and tag rules are satisfied, the required JavaScript libraries are loaded, and data is syndicated.

If no page group rules are satisfied, then no libraries are loaded. If multiple tags that require the same JavaScript library are to be run, the library is loaded only once for the initial tag syndication.
