Prevent rule from being triggered if parameter exists

Avatar

Level 3

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;

}

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.

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;

}

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 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.

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.
