Script timeout
When testing scripts, either by toggling to Preview mode or by using the Script Profiler, a script
timeout is active in the Designer, so that scripts that need a very long time to run are stopped
after a set time. You can adapt this timeout to your needs, as follows:
1. On the menu, select Window > Preferences.
2. Click Scripting.
3. Set a timeout in seconds (for example: 2s) and click OK. The minimum timeout is 1
second.
Note
The script timeout is not active when generating output.
Optimizing scripts
In the process of output generation, the execution of scripts may take up more time than
necessary. To optimize a template, it helps to disable scripts that don't have an effect on the
output; see "Managing scripts" on page884.
This topic presents a number of other ways to speed up script execution by optimizing the
scripts.
Use an ID or class as selector
Scripts (except Control Scripts) start with a query. The selector in the second column in the
Scripts pane is what a script looks for in the template. The selector can be a text, HTML/CSS
tags, or a combination of text and HTML/CSS tags.
Looking for text in a template is a less optimized operation and may impact output speeds in
longer documents. To speed up the output process, it is recommended to use an IDor class as
selector instead. This narrows the scope of the search and results in a very fast query, as
elements with an ID or class are indexed by Connect Designer's layout engine.
For information about how to give an element an ID or class, see "ID and class" on page636.
