如何从应用程序中的任意链接查看JSON数据？

Question

我可以从应用程序内的任意链接查看特定json数组数据中的内容吗？

正如我的演示专家所显示的那样，我的搜索工作正常（搜索“内容”一词）并返回了我想要的内容。 但我也希望能够从应用程序其他位置的某些链接中调用某些返回的数据。

插销方案：单击插销器中的“查看内容集3的信息”链接应在其下方显示内容集3中的信息，但我不知道如何使它工作。

我也很好奇，刷新页面时如何保持内容可见？

的HTML

<!-- Search -->
<div class="well"> 
  <p>Search the term "content"</p>
  <form role="form">
    <div my-search ng-model="selectedContent" class="form-group clearfix search">
      <input type="text" ng-model="selectedContent" ng-options="query as query.searchQuery for query in searchData" bs-typeahead="bs-typeahead" class="form-control search-field"/>
      <button type="button" class="btn btn-primary search-btn" ng-click="updateModel()"><span class="glyphicon glyphicon-search"></span></button>
    </div>
  </form>
</div>

<!-- this link should also return the specified data -->
<a href="">View info for content set 3:</a>

<!-- Dynamic Content -->
<div class="well">
  <h4>{{clickedContent.contentTitle}}</h4>
  <ul>
    <li ng-repeat="item in clickedContent.headlines" ng-bind-html="toTrusted(item.headline)"></li>
  </ul>
</div>

AngularStrap Typeahead部分模板

   <ul class="typeahead dropdown-menu" tabindex="-1" ng-show="$isVisible()" role="select">
        <li role="presentation" ng-repeat="match in $matches" ng-class="{active: $index == $activeIndex}">
          <a href="" role="menuitem" tabindex="-1" ng-click="updateModel(); $select($index, $event)">
              <div class="query" ng-bind="match.label" data-title="{{match.value.popoverTitle}}", data-content="{{match.value.popoverContent}}", data-placement="right", data-trigger="hover", bs-popover></div>
          </a>
        </li>
    </ul>

JS

    var app = angular.module('demoApp', ['ngAnimate', 'ngSanitize', 'mgcrea.ngStrap'])
    .config(function ($typeaheadProvider) {
      angular.extend($typeaheadProvider.defaults, {
        template: 'ngstrapTypeahead.html',
        container: 'body'
      }); 
    });

    app.directive('mySearch', function(){
      return {
        restrict: 'A',
        require: 'ngModel',
        link: function($scope, $element, $attrs, ngModel){
          ngModel.$render = function(){
             if (angular.isObject($scope.selectedContent)) {
               $scope.clickedContent = $scope.selectedContent;
             }
          }
           $scope.updateModel = function() {
             $scope.clickedContent = $scope.selectedContent;
          }
        }
      }
    });

    function MainController($scope, $sce, $templateCache, $http) {

      $scope.selectedContent = '';

      $http.get('searchData.json').then(function(response){
        $scope.searchData = response.data;
        return $scope.searchData;
      });

      $scope.toTrusted = function(headlineHtml) {
        return $sce.trustAsHtml(headlineHtml)
      };

    };

将从控制器获取searchData.json到服务中。 此服务可以缓存数据，因此不需要每个数据，因此不需要再次请求它。 然后，可以将该服务注入需要数据的任何控制器或指令中。
