Zapier JavaScript tool that can be used to search through a string of comma separated values. Outputs the items that were found as a string through the console logs which can be used in further steps in Zapier.

zapier_tag_search.js

output = { hasUseCases: false };

//Make sure to assign the "inputData" to "tags"
var string = inputData.tags;

var array = string.split(',');

var i = [];

//Iterator tool
Array.prototype.contains = function(needle) {
  for (i in this) {
    if (this[i] == needle) return true;
  }
  return false;
};

//Tags that are being searched
const tagsToSearch = ["tag1", "tag2", "tag3"];

//Array that contain the tags that are found by the query tool
const tagsFound = [];

const tagsToSearchLength = tagsToSearch.length;


//Query tool that checks the array of tags
//Adds the found tags into the "tagsFound" array
for (var index = 0; index < tagsToSearchLength; index++) {
  if (array.contains(tagsToSearch[index])) {
    tagsFound.push(tagsToSearch[index]);
  }
};

//Checks to see whether that tagsFound array contains items
//Prints out the found tags to console as a string
if (tagsFound === undefined || tagsFound.length == 0) {
  // tagsFound array is empty or does not exist
  // Couldn't find any tags
} else {
  output['hasUseCases'] = true;
  console.log('' + tagsFound);
};


//You can now map the JavaScript console logs in Zapier and this will output the tags that were found.
