Question

我试图通过各种方法使页脚位于某些内容之下，但似乎解决方案在AngularJS的动态内容方面表现不佳。

当页面大部分为空白时，我希望页脚位于页面底部
页面扩展时（或总体上来说只是很大），我希望页脚被推到内容下方（对页面本身不粘）
- 重定向页面时应遵循相同的逻辑

这是我制作的一个小演示，用来说明我的尝试。我尝试将position: absolute;用于页脚，但是一旦内容扩展，我不知道如何更改（或使用替代项）。

var app = angular.module('myApp', ['ui.router']);
app.config(function($stateProvider, $urlRouterProvider) {
  $stateProvider.
  state("main", {
    url: "/",
    templateUrl: "main.html",
    controller: "mainCtrl"
  }).
  state("small", {
    url: "/other/small",
    templateUrl: "other_small.html",
    controller: "smallCtrl"
  }).
  state("big", {
    url: "/other/big",
    templateUrl: "other_big.html",
    controller: "bigCtrl"
  })
  $urlRouterProvider.otherwise('/');
});

app.controller('mainCtrl', function($scope) {
  $scope.small_text = "aaa";
  $scope.big_text = new Array(100).fill("AAA");
});
app.controller('smallCtrl', function($scope) {
  $scope.small_text = "aaa";
});
app.controller('bigCtrl', function($scope) {
  $scope.big_text = new Array(100).fill("AAA");
});

body {
  height: 100%;
  margin: 0;
}

footer {
  background-color: #999999;
  color: #F1F1F1;
  text-align: center;
}

.footer {
  position: absolute;
  bottom: 0;
  height: 60px;
  width: 100%;
}

.main-view {
  background-color: #F1F1F1;
}

无需使用position: absolute。只需给出一个margin-top，然后将页脚放在DOM的末尾即可。然后，无论您的身体内容结束到哪里，页脚都会自动开始

var app = angular.module('myApp', ['ui.router']);
app.config(function($stateProvider, $urlRouterProvider) {
  $stateProvider.
  state("main", {
    url: "/",
    templateUrl: "main.html",
    controller: "mainCtrl"
  }).
  state("small", {
    url: "/other/small",
    templateUrl: "other_small.html",
    controller: "smallCtrl"
  }).
  state("big", {
    url: "/other/big",
    templateUrl: "other_big.html",
    controller: "bigCtrl"
  })
  $urlRouterProvider.otherwise('/');
});

app.controller('mainCtrl', function($scope) {
  $scope.small_text = "aaa";
  $scope.big_text = new Array(100).fill("AAA");
});
app.controller('smallCtrl', function($scope) {
  $scope.small_text = "aaa";
});
app.controller('bigCtrl', function($scope) {
  $scope.big_text = new Array(100).fill("AAA");
});

body {
  height: 100%;
  margin: 0;
}

footer {
  background-color: #999999;
  color: #F1F1F1;
  text-align: center;
}

.footer {
  margin-top: 20px;
  width: 100%;
}

.main-view {
  background-color: #F1F1F1;
}

Answer 2

您可以尝试以下操作：

<div style="min-height: 100vh;position: relative;padding-bottom: 123px">
  ... // content
  <div style="position: absolute; bottom: 0; height: 123px">
  </div>
</div>

如何使页脚位于页面底部和AngularJS中的内容下方？
