css - 如何在 AngularJS 中将页脚保留在页面底部和内容下方？

问题描述

我尝试使用各种方法将页脚保持在某些内容下方，但似乎解决方案与 AngularJS 的动态内容的行为不符。

这是我为说明我的尝试而制作的一个小演示。我尝试使用我的页脚，但是一旦内容扩展position: absolute;，我不知道如何更改它（或使用替代方案）。

普朗克

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;

解决方案

没有必要使用position: absolute. 只需给出一个margin-top并将页脚放在 DOM 的末尾。然后页脚将自动从您的正文内容结束的地方开始

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;
}
<!DOCTYPE html>
<html ng-app="myApp">

      <a ui-sref="big">Big page</a>
      <hr>
    </header>


    <div class="main-view" ui-view></div>

    <footer class="footer">
      <h4>
        <span>demo website</span> 2018 &copy;

    </footer>

  </div>

      <button ng-click="show_big_text=!show_big_text">

      <div ng-show="show_big_text" ng-repeat="text in ::big_text track by $index">
        {{text}}
