离子链接到视图,获取视图标题的链接标题

标签: angularjs ionic-framework

这是codepen示例。当我点击“科学事实”按钮时,它将被定向到事实页面。

在事实页面中,我必须手动输入view-title="facts",因此标题可以显示标题“事实”。

是否可以自动将按钮文本(科学事实)作为视图标题?

有两种方法可以实现这一目标:

1)最明显的一个是用角度的原型控制器继承完成的。您需要为tabs状态声明一个控制器。 在此控制器的$scope范围内,您可以将按钮的标题和标题定义为范围变量e.x:

$scope.testTitle = 'Scientific Facts';

现在,由于每个其他控制器都继承自tabs控制器,因此testTitle属性也在继承范围内,可用于呈现标题。

我不建议这样做,因为很难知道在哪个控制器中定义了哪些属性,这会让时间变得非常混乱。

2)您可以声明服务并在那里定义title属性。您可以将服务注入控制器以获取title属性。 通过这种方式,您可以保持$scope清洁:

.factory('TitleService', function() {
  var titles = {
    t1:'foobar',
    t3:'baz',
    t4:'bar'
  };
  return titles;
});

我不太确定此请求背后的动机,但解决问题的一种可能方法是将所需的标题添加到重定向到“事实”页面的锚点的URL中,即:

 <a class="button icon icon-right ion-chevron-right" href="#/tab/facts?title=Scientific%20Facts">Scientific Facts</a>

如果您更改到页面的路径以了解该查询参数,则可以使用该页面控制器中的$ stateParams服务来检索该值,即:

 .state('tabs.facts', {
  url: "/facts?:title",
  views: {
    'home-tab': {
      templateUrl: "templates/facts.html"
    }
  }

注意网址“/ facts?:title” - “:title”现在成为$ stateParam服务将获取的参数。现在在你的控制器中你可以这样做:

.controller('FactController', function ($scope, $stateParams) {
  $scope.title = $stateParams.title;
});

现在,您可以通过{{title}}直接从“事实”视图中引用该标题。

这是一个更新的笔,显示这工作。 http://codepen.io/anon/pen/OVMbVX

似乎需要付出很多努力才能传递标题; - )

更好的方法是创建一个“页面名称”服务,它将所有页面名称放在一个位置,然后从两个控制器中获取服务;在主控制器上,您可以使用页面名称来设置锚文本,而在另一个页面上使用它来设置页面标题。有很多方法可以给这只猫上皮。
