7: Invoke Script
Adding Script Association/Trigger
A script is executed in screen-scraper by associating it with some event, such as before or after an extractor pattern is applied to the text of a web page. The script we've just written needs to be executed after screen-scraper has requested the web page and extracted the data we need from it.
Return to the extractor pattern we just created by clicking on the Form submission scrapeable file, then on the Extractor Patterns tab. In the lower section of your extractor pattern, click on the Add Script button.
Tell screen-scraper when to run the script by selecting Once if pattern matches.
Our Write extracted data to a file script will be invoked after the first match is found to the Form data extractor pattern.
