Question

我有一个使用ng-repeat构建的列表，我正在尝试为列表设置动画，因为元素会改变位置。

我试图将这个想法从this codepen开始，然而，我并没有做好让它发挥作用。

需要做的是：

用户点击图钉
如果图钉为灰色（现在为红色），则固定项目需要转到列表顶部（在其过滤范围内）
如果引脚为红色且现在为灰色，则需要在其范围内的所有红色引脚下方。
需要有一个这样的动画，用户可以看到新的红色针脚到达新的位置，反之亦然，新的灰色针脚会放在那里。

如果有人能帮助我那将是非常棒的。

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;
            }
  };




});

Answer 1

我添加了带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。你可以修改它以使其更加花哨

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：
