How to add the custom tag and then appeand the value from one input field into second input field using onkeyup?

Question

Working scenario: The user have 2 input text field in which he can search a game tag and then append the searched tag value to the 2nd input field.

Problem statement: The user want to add new custom tag that is not present in the searched list and then append the value of this new custom tag in the 2nd input field using onkeyup

Here is the working Demo

$(function() {
    $('#vidyagames').tokenInput([{
        id: 7,
        name: "Super Mario"
    }, {
        id: 11,
        name: "Battletoads"
    }, {
        id: 13,
        name: "Pong"
    }, {
        id: 17,
        name: "The Legend of Zelda"
    }, {
        id: 19,
        name: "Metroid"
    }, {
        id: 23,
        name: "Donkey Kong Country"
    }, {
        id: 29,
        name: "Super Smash Bros."
    }, {
        id: 32,
        name: "Star Fox"
    }, {
        id: 35,
        name: "Starcraft"
    }, {
        id: 37,
        name: "Pokemon"
    }, {
        id: 38,
        name: "Minecraft"
    }, {

Answer 1

Given the requirements, and your comment that you want to add to the token list as well, you can do something like the following:

$(function() {

  var newToken;
  var currId = 100; // starting ID for any additions

    $('#vidyagames').tokenInput([{
        id: 7,
        name: "Super Mario"
    },

... skipping data ...

    {
        id: 81,
        name: "Space Invaders"
    }], {
        theme: "facebook",
        hintText: "Know of any cool games?",
        noResultsText: "Nothin' found.",
        searchingText: "Gaming...",
        preventDuplicates: true,
        onAdd: function(item){
          sync(this.tokenInput("get"));
          newToken = null; // without clearing partially typed text would appear as an additional token along with the selected dropdown token
        },
        onDelete: function(item){
           sync(this.tokenInput("get"));
        },
        onReady: function(){

          $("#token-input-vidyagames").keyup(function(event) {

            if (event.keyCode === 13 || event.keyCode === 9 || event.keyCode === 188) // return, tab, or comma
            {
              if (newToken) $('#vidyagames').tokenInput("add", {id: currId, name: newToken}); // add to the list but only if not null
              currId++;
              sync($('#vidyagames').tokenInput("get")); // append tokens to output
            }

            newToken = $("tester").text(); // store typed-in token's value prior to next keypress (otherwise it will be empty next Return, Tab, or Comma keypress)
          });
        }
    }); 
});

Codepen demo: http://codepen.io/anon/pen/egbppd

Any typed entry is retrieved via the value of $("tester").text() at each keyup. If after an Enter, Tab or Comma keyup if it hadn't already been added by the plugin (i.e. it was not found in the existing token list) it adds it as a new token and updates the second input.

Note that ideally you should check first that new tokens haven't been included already or you'll end up with duplicates (with different IDs). I didn't put in that extra piece of logic.
