not the right person to comment on javascript, but can u try to achieve your requirement by using conditional block ?

as Raghuvir says, you should be able to do this with a conditional block / render variable based on an auto submitting prompt.

Yes a conditional block will work.  This is a server-side action however, and that will cause the report to reload the data.  For a quick report this is not an issue, for a report that takes 5 minutes to load, it might be...

Further proof that .js itself is not the risk. But the pool of resources who know Cognos is small.  The pool of resources who know Cognos AND .js is very very small.  Make sure you know what you're committing your company to when you introduce .js.  If you don't know how to hide a simple <div>, then my concern is that you are over your head where .js is concerned.  So, if you're simply trying to learn and expand your horizons, I applaud you.  If you are trying to add bling to your report, I'd suggest sticking with traditional Cognos solutions (conditional blocks).

... my 2 cents.

yes, it is possible to get done through javascript.

enclose your block with a div tag , lets say 'prompt'
Put a button outside the div which on clicking calls a function, lets say toggle
A rough JS logic given below :

button : <input type='button' onClick='toggle()' value='show-hide prompts'>

<script>
function toggle{
if(document.getElementById('prompt').style.display=='none')
document.getElementById('prompt').style.display='block';
else
document.getElementById('prompt').style.display='none';
}
</script>
