我已经使用了水平对齐:"正确",但它不起作用......

<paper-toolbar>
  <paper-icon-button src="AC.png" paper-drawer-toggle></paper-icon-button>
  <paper-menu-button id="sortbt" >
    <paper-icon-button icon="hardware:keyboard-arrow-down" class="dropdown-trigger"></paper-icon-button>
    <paper-menu class="dropdown-content">
      <paper-item>Not pay yet</paper-item>
      <paper-item>paid</paper-item>
      <paper-item>by boss num</paper-item>
    </paper-menu>
  </paper-menu-button>
  <paper-icon-button icon="icons:home" id="homebt" horizontal-align="right"></paper-icon-button>
</paper-toolbar>

我应该怎么做聚合物1.x.

我正在使用角度js来阅读json.

但如果我使用"+ =",它会显示未定义.

var text = '{ "employees" : [' +
'{ "firstName":"John" , "lastName":"Doe" },' +
'{ "firstName":"Anna" , "lastName":"Smith" },' +
'{ "firstName":"Peter" , "lastName":"Jones" } ]}';

var ojt= JSON.parse(text);

var moduleA = angular.module("ModuleA", []);
moduleA.controller("MsgController", function ($scope) {
    'use strict';
    for(var i=0; i<3; i++) {
    $scope.Message += ojt.employees[i].firstName;
    }
    });

结果是这样的:

    undefinedJohnAnnaPeter

怎么了？
