EmberJS 路由器选择完全转换

2018-01-04 10:51 更新

描述

transitionTo或link-to的参数不对应于路由层次结构中的更改，但仅获取查询参数值中的更改。在这种情况下，只有控制器属性将被更新为新的查询参数值以及在URL中。可选的queryParams在路由和控制器上配置哈希。将查询参数的refreshModel配置属性设置为true。

语句

Ember.Route.extend({
   queryParams: {
      queryParameterName: {
          refreshModel: true
      }
   }
});
