预期

在登录之后，选择Ticker应该将该股票代码对象发送到Tags状态。然后，这将启动Tags状态，代码将检查已选择/传入哪个股票代码，然后显示相应的标签列表。

结果

选择自动收报机不会更新标签状态也不会执行任何操作。

请注意，在下面的屏幕截图中，单击Ticker按钮后没有组件或状态日志：

我尝试过的（来自tickers.component控制器）：

$scope.clickTicker = function(ticker) {
    console.log(' Ticker clicked!', $state)
    $state.go('tags', { ticker: ticker });
}

和

$scope.clickTicker = function(ticker) {
    console.log(' Ticker clicked!', $state)
    $state.go('tickers.tags', { ticker: ticker });
}

代码模块

// Tickers module

var tickers = angular.module('tickers', ['ui.router'])

  tickers.config(function($stateProvider) {

    const tickers = {
      parent: 'dashboard',

      url: '/tickers',
      params: {
        ticker: {}
      },
      views: {
        '': {
          templateUrl: 'tickers-template.html',
