animate + ng-repeat 在一个优雅的解决方案中？

【问题描述】：

我有一个使用ng-repeat 构建的列表，我正在尝试在元素更改位置时为列表设置动画。

我试图将这个想法建立在 this codepen 的基础上，但是，我在让它发挥作用方面做得并不好。

需要做的是：

用户点击图钉 如果 pin 为灰色（现在为红色），则固定项需要转到列表顶部（在其过滤范围内） 如果引脚为红色而现在为灰色，则需要在其范围内的所有红色引脚下方。 需要有一个动画来说明这种情况，用户可以看到新的红色图钉移动到新位置，反之亦然，新的灰色图钉移动到新位置。

如果有人可以帮助我，那就太棒了。

This is what I have been working with (JSFiddle)

控制器

angular.module('MyApp', ['ngAnimate'])
.controller('App', function($scope)
  $scope.myData = [
    id: 1,
    historyContact: [
            
                "date": "2017-05-30T04:00:00.000Z",
                "time": "12:12pm",
                "method": "Incoming",
                "direction": "Inbound",
                "result": "answered",
                "notes": "a",
                "pin": true,
                "_id": 1
            , 
                "date": "2017-05-30T04:00:00.000Z",
                "time": "12:12pm",
                "method": "Incoming",
                "result": "answered",
                "direction": "Inbound",
                "notes": "b",
                "pin": false,
                "_id": 2
            , 
                "date": "2017-05-30T04:00:00.000Z",
                "time": "12:12pm",
                "method": "Incoming",
                "result": "answered",
                "direction": "Inbound",
                "notes": "c",
                "pin": false,
                "_id": 3
            
        ]
  ];

  $scope.noteClicked = function(note) 
        console.log("clicked", note)
        if (note.pin == true) 
                note.pin = false;
             else 
                note.pin = true;
            
  ;




);

【问题讨论】：

看起来你在使用小提琴时没有在简单的 css 中编译 .less

这可能是某些 css 无法正常工作的原因。所以谢谢！虽然，它没有回答原来的问题

【参考方案1】：

我已经添加了带有时间戳的位置字段来控制音符位置，还请注意 ng-move、ng-active 等的 CSS 类。您可以修改它以使其更花哨

CSS：

.ng-enter 
  -webkit-transition: s;
  transition: 1s;
  margin-top: 100%;


.ng-enter-active 
  margin-top: 0;


.ng-leave 
  -webkit-transition: 1s;
  transition: 1s;
  margin-top: 0;


.ng-leave-active 
  margin-top: 100%;


.ng-move 
  -webkit-transition: 1s;
  transition: 1s;
  background: gold;


.ng-move-active 
  background: #fff;
 

这是工作小提琴：
