Need help with custom evaluators

Hello.

We have a newssite where customer can buy subscriptions. And they get specific product codes based on what they have bought.

This codesnippet outputs the product codes:

headerScripts.getUserData().active_products;

I saved it just as it is as an evaulator (string).

If I use (with my evaulatorid) in developer tools:

DYO.Q(DYO.CoreUtils.safeEval(DYO.oevals[EVALUATOR_ID].code))
.then(function(result) {
console.log(“Returned value from evaluator:”, result);
});

The output becomes:

Returned value from evaluator: (2) ["gpdigitalny", "gp_digital_bas_product"]

If I understand it correctly, I get in this case two values.

In my targeting condition I select in “where”:
Custom Evaulator > myevaulatorname > is > gp_digital_bas_product

I assume my skills with javascript combined with how it is supposed to work with Dynamic Yield is limited.

Any advice on what to do here? I hope I explained myself as clear as possible here 

Kind regards
Johan

  Hi Johan,
  It sounds like

  headerScripts.getUserData().active_products;

  returns an array, and not a string.
  Is this the case? and if so, do you always need value from index 1 ?
  If so, you can try and return

  headerScripts.getUserData().active_products[1]

  Thanks for your help.

  Yes it should be an array when you mention it. I tried your suggestion, just to output for instance " gp_digital_bas_product".

  But the condition doesn’t trigger here either.

  But the thing is that a user can have multiple products. And I need to find a way to output them all, and in my targeting condition select the one I would like to target.

  I tried like this:

  headerScripts.getUserData().active_products.toString();

  That outputs:
  gpdigitalny,gp_digital_bas_product

  But that did not seem to work either. What preferred output should I get when I use:

  DYO.Q(DYO.CoreUtils.safeEval(DYO.oevals[EVALUATOR_ID].code))
  .then(function(result) {
  console.log(“Returned value from evaluator:”, result);
  });

  Thanks for your help. I upload some screenshots on how it looks like now:

  Since the result of toString() is:
  gpdigitalny,gp_digital_bas_product
  Targeting by the value IS gp_digital_bas_product will not work.
  You can try using CONTAINS instead of IS (since gp_digital_bas_product is contained in gpdigitalny,gp_digital_bas_product).

  There is also a possibility that the evaluator is running before the object
  headerScripts.getUserData().active_products
  is loaded to the page (since evaluators usually run very early on the page load)

  Thanks for your awesome help!! You are correct on booth. 

  It seems to work now, when I also set an delay for the notification to display.

  Let us say a customer have these product codes:
  gp_digital_bas_product,gp_digital_bas_product_campaign

  As i see it, using “contains” as target condition will trigger them booth? 

  Kind regards
  Johan

  I assume there is no way to seperate them? I can’t see any possible issue here, just asking in case of.

  Hi Johan,
  How about returning a string, something like:

  '|' + headerScripts.getUserData().active_products.join('|') + '|';

  
  Then you can target by Evaluator contains ‘|gp_digital_bas_product|’, knowing that all the elements will be surrounded by pipes.

  You can also use Asynchronous Evaluators to build the delay into the targeting.

  Just an idea, wrap each item with brackets

  headerScripts.getUserData().active_products.map(function(i){
  return '['+i+']'
  }).toString();

  Now the result will be [gp_digital_bas_product],[gp_digital_bas_product_campaign]
  if you target by CONTAINS [gp_digital_bas_product] it will fall only on the correct one
