html - CSS滑入滑出动画溢出问题

标签 html css angularjs css-animations ng-animate

我正在尝试对屏幕外的图 block 列表进行动画处理，同时对屏幕上的新图 block 列表进行动画处理。

我使用 Angular 的 ng-for 来循环访问一系列可见项，因此技术上只有一个列表，但 Angular 的 ngAnimate 模块会保留被逐出的项一直存活到动画完成为止。

我的问题是，每当两个图 block 列表在动画中间同时出现在屏幕上时，一个列表就会溢出并最终位于另一个列表的下方。

这就是正在发生的事情:

这就是我想要它做的事情:

我尝试过使用 CSS 转换、绝对定位，但我似乎无法做到正确。

这是一个 fiddle 的工作示例:http://jsfiddle.net/soethzfm/7/ 

(function() {
  var app = angular.module("animationApp", ["ngAnimate"]);

  app.controller('FrameController', ['$scope',
    function($scope) {

      $scope.message = 'Hello world';
      $scope.items = [];
      $scope.visibleItems = [];
      for (var i = 3; i < 9; i++) {
        $scope.items.push({
          name: 'Item ' + (i - 2),
          color: "#" + (i) + "0" + (i % 5) + "0" + (i % 4) + '0'
        });
      }


      $scope.firstThree = true;
      $scope.selectNextItems = function() {

          $scope.firstThree = false;
          $scope.visibleItems = [$scope.items[0], $scope.items[1], $scope.items[2]];

最佳答案

您面临的问题是因为内容被包裹在父容器中。父容器的宽度仅为 400 像素，但每个框的宽度为 100 像素 + 2 * 5 像素(边框)。因此，同一行中只能容纳 3 个盒子，其余的必须绕到下一行。当您使所有 6 个元素同时可见时，这一点可以非常清楚地看到。正如您在下面的代码片段中看到的，最后 3 项环绕到下一行。

注意:我对 AngularJS 一无所知，所以请原谅我试图让所有六个同时可见的糟糕尝试。

(function() {
  var app = angular.module("animationApp", ["ngAnimate"]);

  app.controller('FrameController', ['$scope', function($scope) {
   
    $scope.message = 'Hello world';
    $scope.items = [];
    $scope.visibleItems = [];
    for (var i = 3; i < 9; i++) {
      $scope.items.push({
        name: 'Item ' + (i - 2),
        color: "#" + (i) + "0" + (i % 5) + "0" + (i % 4) + '0'
      });
    }


    $scope.firstThree = true;
    $scope.selectNextItems = function() {
      if ($scope.firstThree) {
        $scope.firstThree = false;
        $scope.visibleItems = [$scope.items[0], $scope.items[1], $scope.items[2], $scope.items[3], $scope.items[4], $scope.items[5]];
      } else {
        $scope.firstThree = true;
        $scope.visibleItems = [$scope.items[3], $scope.items[4], $scope.items[5]];
      }
    }
    $scope.selectNextItems();
  }]);
})()
.item-container {
  width: 400px;
  border: 1px solid red;
  overflow: hidden;
}
.item {
  color: white;
  width: 100px;
  height: 150px;
  border: 5px solid #F3F5F6;
  display: inline-block;
  position: relative;
  cursor: pointer;
}
.item:hover {
  padding: 2px;
  border: 3px solid blue;
}
/* Animations */

.item.ng-move,
.item.ng-enter,
.item.ng-leave {
  transition: 1400ms cubic-bezier(0.250, 0.250, 0.750, 0.750) all;
}
.item.ng-enter,
.item.ng-move {
  left: -80%;
}
.item.ng-enter.ng-enter-active,
.item.ng-move.ng-move-active {
  left: 0%;
}
.item.ng-leave {
  right: 0%;
}
.item.ng-leave.ng-leave-active {
  right: -100%;
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.5/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.5/angular-animate.min.js"></script>
<div ng-app="animationApp">
  <div ng-controller="FrameController as vm">

    <button ng-click="selectNextItems()">Next Page</button>

    <div class="item-container">

      <div class="item" ng-repeat="item in visibleItems" ng-style="{'background-color': item.color}">
        {{item.name}}
      </div>
    </div>
  </div>
</div>

通过向父容器添加 white-space: nowrap 设置，可以轻松解决此问题。通过这样做，我们可以让所有六个元素排列在同一行，这样动画过程中看到的不匹配就会消失。

(function() {
  var app = angular.module("animationApp", ["ngAnimate"]);

  app.controller('FrameController', ['$scope', function($scope) {
   
    $scope.message = 'Hello world';
    $scope.items = [];
    $scope.visibleItems = [];
    for (var i = 3; i < 9; i++) {
      $scope.items.push({
        name: 'Item ' + (i - 2),
        color: "#" + (i) + "0" + (i % 5) + "0" + (i % 4) + '0'
      });
    }


    $scope.firstThree = true;
    $scope.selectNextItems = function() {
      if ($scope.firstThree) {
        $scope.firstThree = false;
        $scope.visibleItems = [$scope.items[0], $scope.items[1], $scope.items[2]];
      } else {
        $scope.firstThree = true;
        $scope.visibleItems = [$scope.items[3], $scope.items[4], $scope.items[5]];
      }
    }
    $scope.selectNextItems();
  }]);
})()
.item-container {
  width: 400px;
  border: 1px solid red;
  overflow: hidden;
  white-space: nowrap;
}
.item {
  color: white;
  width: 100px;
  height: 150px;
  border: 5px solid #F3F5F6;
  display: inline-block;
  position: relative;
  cursor: pointer;
}
.item:hover {
  padding: 2px;
  border: 3px solid blue;
}
/* Animations */

.item.ng-move,
.item.ng-enter,
.item.ng-leave {
  transition: 1400ms cubic-bezier(0.250, 0.250, 0.750, 0.750) all;
}
.item.ng-enter,
.item.ng-move {
  left: -80%;
}
.item.ng-enter.ng-enter-active,
.item.ng-move.ng-move-active {
  left: 0%;
}
.item.ng-leave {
  right: 0%;
}
.item.ng-leave.ng-leave-active {
  right: -100%;
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.5/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.5/angular-animate.min.js"></script>
<div ng-app="animationApp">
  <div ng-controller="FrameController as vm">

    <button ng-click="selectNextItems()">Next Page</button>

    <div class="item-container">

      <div class="item" ng-repeat="item in visibleItems" ng-style="{'background-color': item.color}">
        {{item.name}}
      </div>
    </div>
  </div>
</div>

但正如您在输出中看到的，这些 Action 似乎不太无缝。其原因是因为位置设置并不安静。如前所述，我对 Angular 动画的工作原理知之甚少，因此无法完全修复它们，但对进入、离开和移动使用相同的位置属性将是一个起点。如果我们在事件过程中将位置从 left 修改为 right 或反之亦然，则 transition 效果将失效，并且只是导致瞬间跳跃。您在代码片段中需要注意的另一件事是，我修改了定位值，以使效果看起来更平滑。但这些都是在反复试验的基础上完成的。我强烈建议您首先使用纯 CSS 来实现整个事情，然后将其移植到 AngularJS。

(function() {
  var app = angular.module("animationApp", ["ngAnimate"]);

  app.controller('FrameController', ['$scope', function($scope) {
   
    $scope.message = 'Hello world';
    $scope.items = [];
    $scope.visibleItems = [];
    for (var i = 3; i < 9; i++) {
      $scope.items.push({
        name: 'Item ' + (i - 2),
        color: "#" + (i) + "0" + (i % 5) + "0" + (i % 4) + '0'
      });
    }


    $scope.firstThree = true;
    $scope.selectNextItems = function() {
      if ($scope.firstThree) {
        $scope.firstThree = false;
        $scope.visibleItems = [$scope.items[0], $scope.items[1], $scope.items[2]];
      } else {
        $scope.firstThree = true;
        $scope.visibleItems = [$scope.items[3], $scope.items[4], $scope.items[5]];
      }
    }
    $scope.selectNextItems();
  }]);
})()
.item-container {
  width: 400px;
  border: 1px solid red;
  overflow:hidden;
  white-space: nowrap;
}
.item {
  color: white;
  width: 100px;
  height: 150px;
  border: 5px solid #F3F5F6;
  display: inline-block;
  position: relative;
  cursor: pointer;
}
.item:hover {
  padding: 2px;
  border: 3px solid blue;
}
