Note that most resources on the web are about JavaScript in the browser, but the greatest
majority of the tips do, indeed, apply to scripts in general, wherever they are used.
The script flow: when scripts run
When Connect generates the actual output – letters, web pages or emails -, it opens a record
set and merges it with the template. It takes each record, one by one, and runs all scripts for it,
in a specific order, as explained below.
First all Control Scripts are executed, in the order in which they appear in the Scripts pane.
Control scripts don't touch the content of the sections themselves, but they change the way a
template is outputted, for example by selecting or omitting sections from the output (see
"Control Scripts" on page890).
Then the Standard scripts are executed, once for each section, in the order in which they
appear in the Scripts pane.
Standard scripts can change the contents of the current section in a template.
This type of script must have a selector: text, an HTML element and/or a CSS selector (see
"Writing your own scripts" on page853 and "Selectors in Connect" on the next page).
Running a template script starts with looking in the current section for pieces of content that
match the script's selector.
Important to note is that if nothing matches the selector, the script is not executed.
In a Print context, the Standard scripts in the Scripts pane run once for each section and then
for each Master Page (see "Master Pages" on page485). Next, each processed Master Page is
put behind every page to which it should be applied.
Scripts are NOT executed again for every page.
Finally, Post Pagination Scripts run, in the order in which they appear in the Scripts pane
(see "Post Pagination Scripts" on page906).
Post Pagination Scripts are run in a Print context after the content has been paginated.
Because they can search through the output of all Print sections, and modify Print sections (one
at a time), they may be used to create a Table Of Contents (TOC), as explained in the topic:
"Creating a Table Of Contents" on page908.
Note
Any JavaScript files included in a section run after the scripts in the Scripts pane.
