React - do spotify oauth with React

spotify-oauth-in-react.js

var React = require("react");

module.exports = React.createClass({
    ...,
    // open new spotify oauth window
    handleLoginRequest: function(){
        var url = 'https://accounts.spotify.com/authorize' + 
                '?client_id=' + this.props.clientId +

        var hash = JSON.parse(event.data);
        if (hash.type == 'access_token') {
            console.log(hash.access_token);
             //do things here
        }
    },
    // add event listener to spotify oauth callback message
    componentDidMount: function(){
        window.addEventListener("message", this.handleLoginRequestCallback, false);
    },
    render: function() {
        ...
    }
});

spotify-oauth-proxy.js

// create another html page to receive oauth callback、parsing query string and do postMessage to opener
(function() {
      var hash = {};
      window.location.hash.replace(/^#\/?/, '').split('&').forEach(function(kv) {
        var spl = kv.indexOf('=');
        if (spl != -1) {
          hash[kv.substring(0, spl)] = decodeURIComponent(kv.substring(spl+1));
        }
      });
      
      console.log('initial hash', hash);
      
      if (hash.access_token) {
        window.opener.postMessage(JSON.stringify({
          type:'access_token',
          access_token: hash.access_token,
          expires_in: hash.expires_in || 0
        }), '*');
        
        window.close();
      }
})();

Does this method works on a mobile browser ?
