Polymer, how to get url params in page.js into polymer element? - polymer

Question

I want to make a single page application. When I go to path like localhost/person-info/101, how can I get the URL params using page.js into a Polymer element?
I have to use these params to select or change data in the person-info element before using neon-animated-page to change page
Contents of app.js:
window.addEventListener('WebComponentsReady', function () {
var app = document.querySelector('#app');
page('/', home);
page('/person-info/:user', showPersonInfo);
page({
hashbang: true
});
function home() {
app.route = 'index';
console.log("app route" + app.route);
console.log("home");
}
function showPersonInfo(data) {
console.log(data);
console.log(data.params.user);
app.params = data.params;
app.route = 'person-info';
}
});
And my 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;
}
a {
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 is global, so if you bind a data to app.params from your route than you can access it everywhere using app.params. Or just access your element and set the properties on your element like below
function showPersonInfo(data){
var personInfo=document.querySelector('person-info');
personInfo.user=data.params;
app.route = 'person-info';
}
From your person-info element you can access by using this.user but i think you need to set the property user on element properties.
