and polymer element person-info.html

<link rel="import" href="bower_components/iron-list/iron-list.html"> <link rel="import" href="bower_components/polymer/polymer.html"> <link rel="import" href="bower_components/paper-toolbar/paper-toolbar.html"> <link rel="import" href="bower_components/paper-icon-button/paper-icon-button.html">  <script type="text/javascript" src="bower_components/jquery-2.1.4.min/index.js"></script> <script src="js/app.js"></script>  <dom-module id="person-info">     <style>         :host {             display: block;             font-family: sans-serif;             @apply(--layout-fit);             @apply(--layout-vertical);         }          .toolbar {             background: #3f78e3;            }          {             color:#fff;         }     </style>     <template id="person-info">         <paper-toolbar class="toolbar">             <a href="/">                 <paper-icon-button icon="icons:arrow-back"></paper-icon-button>             </a>              <div>test</div>             <div>test</div>         </paper-toolbar>         <content></content>     </template>     <script>         polymer({             is: 'person-info',             ready: function () {                 console.log("person-info page");                 this.testdd = "adisak";                 console.log("user ---->"+this.params);                 console.log(this);             },             properties: {                 dataindex: string             }         });     </script> </dom-module> 

variable app global, if bind data app.params route can access everywhere using app.params. or access element , set properties on element below

function showpersoninfo(data){     var personinfo=document.queryselector('person-info');     personinfo.user=data.params;     app.route = 'person-info'; } 

from person-info element can access using this.user think need set property user on element properties.
