Prevent rule from being triggered if parameter exists

Hi there,

I just set up a page load rule. The only condition for this rule is that it is not triggered if a certain parameter exists. Unfortunately AEM only offers me the possibility to trigger the rule if a parameter is pressent. Can you tell me if it is also possible to prevent a rule from being triggered if a parameter exists?

Thank you

    If you can test for the parameter using javascript then you can accomplish this using a custom condition on the rule.

    If a custom condition does not return true, then the condition is not met and the rule will not fire.

    As an example, you could use this javascript in a DTM custom condition:

    var paramExists = true; //replace this with code to determine existence of the param

    if (paramExists) {

      return false;

    } else {

      return true;

    }

    Hi Stewart, hi Jantzen,

    thank you for your feedback and your discussion. Sorry for my late response, it took me a while to put everything in place. Actually the solution Stewart suggested worked perfectly well. I used the above mentioned code to prevent the rule from being fired if a certain parameter existed.

    Thanks again guys. This helped a lot.

      Jantzen,

        I think we're saying the same thing.

      Florian,

        Let us know if you are all set.  I guess, If I got it wrong, swap the return statements in the custom condition.

        Stewart,

        Wouldn't it be opposite? Florian is wanting to not trigger the rule if parameter2 exists. I believe your code reads

        If parameter2 does not equal null (IE if parameters contains a value), return false and thus do not fire the rule

        Wouldn't you want to remove the ! from your code so that it read

        if parameter 2 equals null, return false and thus do not fire the rule

        Thanks,
        Jantzen

          I think I'd do it this way -

          Create a DTM data element for parameter2 call it qsParam2.

          Then the code becomes :

          if (_satellite.getVar('qsParam2') != "") {

          return false;

          } else {

          return true;

          }

            Great, thanks stewarts16448458​

            Unfortunately I am afraid I am not exactly sure what i have to insert for "//replace this with code to determine existence of the param". Could you give me an example. Let's say my url is xyz.com?parameter1=a&parameter2=b and I want do not want the rule to be triggered if parameter2 exists.

            Thank you very much.

            Florian
