如何在滚动间谍中隐藏其他内容，而不是滚动到特定位置

时间：2019-02-12 16:53:57

标签： javascript jquery html css angularjs

我有一些带有链接的内容。我在这里使用scrollspy。每当我单击一个链接时，它就会滚动到特定的div，并且菜单将处于活动状态。但是在这里，不是滚动，我需要隐藏其他div并显示特定/匹配的div。我的意思是在这里而不是滚动，我需要隐藏并显示内容。这是更新后的代码https://plnkr.co/edit/VvV7T0FCdXirQfMROwi2?p=preview

您需要为每个div设置可见性，然后根据链接的点击次数对其进行切换...要使其正常工作，我们需要将每个对象的可见性状态存储在$scope.groups数组中。为此，我们在数组的每个对象中引入了一个新变量visible，对于默认情况下需要显示的对象，我们将其设置为true-单击顶部的链接即可显示其余变量。 / p>

检查以下工作示例：

var app = angular.module('app', ['ui.bootstrap', 'ngSanitize', 'angular.filter']);
app.controller('AccordionDemoCtrl', function($scope, $location, $anchorScroll) {
  $scope.oneAtATime = true;
  $scope.visibleGrid=-1;

  $scope.gotoDiv = function(x) {
    $scope.visibleGrid=x;
    $scope.groups.forEach(a => {
      /* console.log(" we got ID:" + x + " & looking it against the ID:" + a.id); */
      a.isOpen = true;
    });

  };

  $scope.groups = [{
      title: 'title 0',
      id: '0',
      list: ['<i>item1a</i> blah blah',
        'item2a',
        'item3a',
        'item4a',
        'item5a',
        'item6a',
        'item7a'
      ]
    },
    {
      title: 'title 1',
      id: '1',
      list: ['<i>item1a</i> blah blah',
        'item2a',
        'item3a',
        'item4a',
        'item5a',
        'item6a',
        'item7a'
      ]
    },
    {
      title: 'title 2',
      id: '2',
      list: ['<i>item1a</i> blah blah',

更新：默认情况下（在用户评论之后），所有数据都将显示，然后在单击特定的按钮后，只有相关部分保持可见

更新＃2 ：（在用户的第二条评论之后）相同的结果，但未在JSON数据中添加任何内容
