How can I clear a Multi-Select and Multi-Line Text Box Prompt Choices?

[cognosdelaware]

Hi,

  I have a Text Box Prompt with the "Multi-Select" and "Multi-Line" properties set to Yes.

  When I enter some values in the Text Box Prompt, click "Insert", they populate the "Choices:" box next to the "Insert" button, is there a way to clear these values in javascript(Clear the values under the "Choices:" area)?

Thanks

Below the list of choices there's a Select All option. Click that then click remove...

I meant through JavaScript

I know you did, but I don't understand why you'd go to the hassle of saving a single mouse click. You could write something that then breaks in the next release of Cognos...

The reason is, that I have two types of these controls and based off a radio button selection, when the user goes between both, I want to clear the one they did not chose, otherwise it would run the report with choices in both controls.

if that is the goal, i'd achieve that differently:

- create a boolean variable

Code Select Expand

paramcount('pPrompt1') > 0
and
paramcount('pPrompt2') > 0
- create a new report page with a static text explaining that the user should not have choices in both prompts
- set the variable above as the render variable for this page in case of true value
- set the variable above as the render variable for your actual report page in case of false value

You don't need to clear the other prompt...if you write your filter correctly it'll be ignored anyway - something along the lines of:

Code Select Expand

(?pRadioButton? = '1stOption' and [Field1] in ?p1stPrompt?) or (?pRadioButton? = '2ndOption' and [Field2] in ?p2ndPrompt?)

My issue is that I have 3 controls:

1) Value Prompt with 2 static choices displayed as Radio button group
    1(This is the Use value) and "Choice1" (This is the Display value of the first radio button)
    2(This is the Use value) and "Choice2" (This is the Diplay value of the second radio button)

2) Text Box Prompt with parameter value called "parmCusip" and Name property called "CUSIP"
3) Text Box Prompt with parameter value called "parmAccountNumber" and Name property called "ACCOUNTNUMBER"

When "Choice1" radio button is selected the "ACCOUNTNUMBER" Text Box Prompt should have it values cleared(values under the  "Choices:" area), this is in case a user entered a series of Account Numbers.

Vice-Versa for "Choice2"

If I understand, the user can filter on one of two possibilities - CUSIP or ACCOUNTNUMBER. That choice is driven through the use of the radio prompt.

Is the requirement to clear and disable the prompt to prevent the filter from activating? Why not make the prompt value part of the filter logic? If you're using DQM mode, you can do something like:

Code Select Expand

#
prompt('Choice','token')
when 'Choice1' then '[Namespace].[Dim].[CUSIP] in ' + promptmany('CUSIP','string','NA')
when 'Choice2' then '[Namespace].[Dim].[ACCOUNTNUMBER] in ' + promptmany('ACCOUNTNUMBER','string','NA')
else '1=2' /*invalid choice, someone is playing games*/
#

That way only the correct filter will ever be used, even if both prompts have values.

If you must clear the prompt you can do something like:

Code Select Expand

<script>
var paulScripts ={}
  , oCR = cognos.Report.getReport("_THIS_");

paulScripts.getControl = function(promptName) {
  return oCR.prompt.getControlByName(promptName);
};


paulScripts.getControl('ChoicePrompt').setValidator(function(values){
var choice = values[0].use;

if(choice=='Choice1') {
  paulScripts.getControl('ACCOUNTNUMBER').clearValues();
  paulScripts.getControl('ACCOUNTNUMBER')["@disabled"]=true;
  paulScripts.getControl('CUSIP')["@disabled"]=false;
}
if(choice=='Choice2') {
  paulScripts.getControl('CUSIP').clearValues();
  paulScripts.getControl('ACCOUNTNUMBER')["@disabled"]=false;
  paulScripts.getControl('CUSIP')["@disabled"]=true;
}

});

</script>


The flags are not currently supported in Cognos Analytics, but there is an easy way to access the element through the Prompt API. If you're looking to upgrade the JavaScript will be difficult, but not impossible, to adapt.

I ended up doing the following that works and for others in case they need it:

When a user clicks on the other radio button, this code fires on the click event:

var oCR = cognos.Report.getReport("_THIS_");
var myPrompt = oCR.prompt.getControlByName("CUSIP"); //for the control, you need to have its NAME property set
myPrompt.clearValues();

Thanks for all the help.
