Cognos javascript documentation

In this article I continue to explore ways to use custom JavaScript in Cognos to modify prompts. In all of the versions of Cognos, many people had complaints about the way prompts looked or behaved.

From the default settings in the search and select prompts, to making checkbox prompts horizontal. So now is our chance to rewrite those to meet our needs. One of the first JavaScript widgets I wrote was to make checkbox prompts horizontal.

It looped through all of the options, and applied an inline display:inline-block to each of them. It worked quickly and efficiently, and a lot of people used it. Cognos Analytics gives us the opportunity to improve on this script.

The HTML structure of the radio prompt is pretty simple. Simplified, it looks like:. We can simply loop through all of the divs with the class clsListView and set those to inline-block. This is a little less pretty, but still workable. Any changes we do to those rows are lost whenever a user selects all of the prompts.

Instead, we have to be clever here. If the style node already exists, we can skip it.

The new select and search prompts are gorgeous. Streamlined, fast, wide. Seriously wide. Well, maybe not as wide as it used to be. It went on a relatively ineffective diet.

One that would fit nicely on a dashboard. Create a new button to manually trigger it, and trigger it when a user searches for something. The vast majority of the code is actually formatting the prompt so it looks good after we apply position:absolute to all of the divs. I have seen the occasional request for advanced formatting options in prompts.

When a value is selected, the background color should be different, the cursor should be set to a pointer, the text should spin around whenever the user hovers over it. Therefore the way to solve this is to give the report developer the ability to specify the styles wanted for each individual prompt. The script will then take the element ID of the prompt, and prepend that before the generated classes. This allows a developer to specify two separate styles for two separate prompts of the same type.

The configuration file for this script is significantly more advanced than the previous scripts. Here, not only do we specify the name of the prompt, but we write in the desired CSS. This is done by means of an array in the config JSON:.Nice post.

Office and so on. While IBM will strive to provide compatibility from release to release of Cognos 8 Viewer, all support and compatibility issues are the responsibility of the user and not IBM. Therefore, the use of the techniques comes with the risk of partial or complete incompatibility with the possibility of necessitating a partial or complete change or loss of functionality from release to release.

Such risk is borne entirely by the user of these techniques.

So I am using jQuery in my reports and I have a suite of reports that all load thanks to jQuery all at once so the customer feels like the transitions are faster because they don't have to wait between each click.

I want to be able to have all reports change based off of a prompt the customer uses. So if they select a specific day, all of the reports in the suite will change to that day. Or if they have a specific area they select, all of the reports go to that area. This will make it so the customer doesn't have to load the parameters in the prompt for each report.

I am wonderin if there is a way to do this. I have looked and haven't found anything. So in my report that houses all of the iframes and the value prompt that I have named changeMonth I have this JS.

They were both drop down lists if that matters. I see that you listed them as radio buttons so I will try that here in a moment and let you know if that changed anything. But how I have it setup, is there something else i should be doing?

I was able to get this to work by creating a JavaScript function in each child report which changes a hidden prompt value which the query depends on and then reprompts the page.

Here is the portion of the code that needs to be in every child object:. There's more info here:.

Which of the following was a result of the tea act of 1773_

In the container report I created a Cognos radio button value prompt. I coded the JavaScript to leverage the built-in onchange validation hook provided by Cognos in the API to run code when the radio button has changed. The code loops through all iFrames and calls the function defined above in each child report passing in the value of the radio button selected. Note that in the above code the strings 'controlname' and 'radio' correspond to the Name property of the prompt controls in question.

By default Cognos does not give prompt controls a name. Thus, you have to supply the name after creation. This technique can be modified to take input from any of the variety of prompt controls available in Cognos.

Additionally, in theory, the container doesn't even have to be Cognos at all. The only caveat is due to security restrictions browsers do not allow calling of functions within iFrames from containers that have a different domain than the iFrame. This is something to consider when designing a solution.

First you might ask, what are extensions? As I wrote about in a previous article extensions allow you to modify the UI, adding or removing features as you like. One of the features of that article was an early version of the Clipboard Editor.

My good friend Michael Hoggard and I worked on it to add a new feature, and to clean it up a little. One of my biggest issues with building reports is testing out different prompt scenarios. We could run the report and manually set each prompt, but that can be incredibly time consuming. This interface allows you to add, remove, and change session level parameters in the report.

When running in interactive mode, you an also use it to see exactly what parameters were sent through a drillthrough. When previewing a report, you can also play with the parameters. See what happens when you change them from one scenario to another. As you can see you can set both the display and use values.

The plus button allows you to add multiple values for each parameter. If only one of the boxes is empty, it will use the value from the other box.

These are session level parameters as opposed to report level. Data Modules present a host of opportunity. I feel there is a lot of room for improvement in the UI, especially when it comes to quickly editing multiple items. Despite many requests, changing the default search type from starting However, one big whopping change is the popup element containing the search items is no longer inside the search control.

This makes the old script useless, and finding that popup is incredibly difficult. In Cognos This obfuscation means we have to rely on trickery and shenanigans. In order to use it, you need to give the search prompt a name, like mySnS. The custom control needs to have the following configuration:. Important note! Hopefully methods like this will be exposed with a consistent name in future versions.

Can you guess what happened to me this morning? Fortunately, the application JavaScript we need is not obfuscated. I'm not feeling at all defensive about it.

Can somebody share the script or step to do this. Thanks for very useful article, wish I would had had this couple of years ago when I did my first tunings with JavaScript in Cognos8. In the old page this: document.

FYI that this is solved now. I assumed that the syntax except for those object name conventions would be still the same, but actually it was exactly as you wrote here. Thanks once more for this great article! I have this blog now in my RSS-feed, so all similar posts are highly appreciated. Now my Cognos reports can finally come into web 2.

Have written this recipe to help some of the other developers to develop reports integrating external charts using Cognos Custom Control. Objective is to share how the custom chart can build and integrated with charts like d3, Plotly, Highcharts etc.

Understanding of functions, arrays and objects would become key for any body to get the clarity of how data is read from Cognos queries and passed into javascript arrays and then subsequently use the same to plot the charts.

Some of the customers i have worked, often ask if we can get some of the basic user interaction or latest visualization charts in Cognos. So to meet those requirements we have developed quite a custom scripts to integrate some of the charts like d3, c3, plotly charts, HighCharts etc.

Below article is to start sharing with some basic examples. Shall keep updating the article as and when we refine more examples. Not other intent or objective. If people have good inputs to refine further, requesting to please share your best experience. Please do leave a like note if the below article helped to any extent. This will help!!! Custom Control is the new capability that is been provisioned or provided in Cognos 11x.

This basically help Cognos developers to enhance visualization charts to meet expectations in line with bootstrap charts, d3 charts etc. This is just a beginning step to start with. In some of the chart examples the data can be populated from csv files or xls files or anything. Having know where the source of the data is being received, creating equivalent Cognos query objects are important.

Below are some of the snapshots where i have taken an example of reading d3 chart into Cognos. In the above chart, we have used a simple data. This chart had a d3 code reference already built to replicate the chart, but here, we have used the same code to integrate with-in Cognos.

Post the data file is uploaded, we tagged the file to test module and made sure that module is avaialble as package to create an independent query. This is one of the requirement of Cognos. If the path is given else where, then complete path needs to mentioned. Understanding the structure of JavaScript in relation to Cognos is very important. There are certain steps that needs to be mentioned in the script and also sharing the final code snipped that i have used to make the chart working.

In the below example, i am referring to pyramid. This is important to understand as this is where related filters gets applied to the charts when Cognos reports filters are applied. Below is the snapshot of the example where i have taken from Cognos d3 example and extended it to Triangle chart.

Link where pyramid.
