Advanced Javascripting in Cognos
- 1. www.OurStudentsOurFuture.org Building a Foundation of Strong Leaders
- 2. www.OurStudentsOurFuture.org Supporting & Developing Future Leaders The Hillsborough Principal Pipeline consists of four integrated components: 6/9/20142
- 3. www.OurStudentsOurFuture.org Leader Selection Tool Focused on Component 3 (Selective Hiring) • Used for making data driven hiring decisions. • Used to match the right leader to the right school vacancy. 6/9/20143
- 5. www.OurStudentsOurFuture.org Business Requirements • Need a solution to filter many different attributes and interact within list • Select rows within the candidates list and be able to do side-by-side comparisons • View detailed resume style report for selected candidates after analysis • Consume different reports in specified formats only (pdf, excel, html)
- 6. www.OurStudentsOurFuture.org Overall Solution Design • Set of three reports • Main report needed extended functionality • Turn off Cognos Toolbar • Hide Multiselect prompt choice lists until clicked • Reset report button • Add checkboxes to list object • Pass checked row values to drill-through reports
- 8. www.OurStudentsOurFuture.org Using JavaScript in Cognos Some examples of common uses: • Hide Cognos toolbars • Validate input boxes • Manipulate default prompt selections • Automatically reprompt • Mimic built in Cognos capabilities (button for pdf, excel, drill up , drill down) • Passing data values • Changing default behavior of Cognos elements
- 9. www.OurStudentsOurFuture.org Considerations for using JavaScript • Extra testing will be needed when migrating reports to another environment • Extra regression testing will be needed should there be an upgrade, patch • Know what browsers you support and Cognos is compatible with based on version. Make sure you test compatibility between browsers
- 10. www.OurStudentsOurFuture.org • Typing in parameter names and arguments • Standard debug tools/techniques • Parameter/list names don’t propagate • Code may behave differently in Cognos viewer versus Report Studio Considerations for using JavaScript
- 11. www.OurStudentsOurFuture.org Tips / Best Practices • Using tags • Layout component references for html items that are used across multiple reports • Place .js file on gateway servers and call script • Utilize Prompt API
Editor's Notes
- - Users don’t need to see the standard toolbar Standard multi select prompts take up a lot of room, report has numerous prompts Need to reset all the prompts gracefully Need a way for user to choose candidates Pass values ot other reports
- Enhance the standard capabilities of Cognos using JavaScript. Cognos is a web based application, you can embed JavaScript in HTML tags Report runs in HTML format, the JavaScript in those HTML tags will execute. Create a script, save it to a location accessible to the calling server and include that script in the report.
- -JavaScript could be turned off in browsers because of security reasons.
- Heavily used code should be consolidated in one location via a script or layout comp Consider if scripts can be put on the servers Prompt API provides cleaner way to manipulate/interact with prompts
