AngularJS 与 W3.CSS



您可以轻松地将w3.css样式表与AngularJS一起使用。本章将演示如何使用。


W3.CSS

在您的 AngularJS 应用程序中包含 W3.CSS,将以下行添加到文档的头部:

<link rel="stylesheet" href="http://cdn.w3schools.wang/w3.css">

如果您想学习 W3.CSS,请访问我们的 W3.CSS 教程

以下是一个完整的HTML实例,其中介绍了所有 AngularJS 指令和 W3.CSS 类。


HTML 代码

<!DOCTYPE html>
<html>
<link rel="stylesheet" href="http://cdn.w3schools.wang/w3.css">
<script src="http://cdn.w3schools.wang/libs/angularjs/1.4.8/angular.min.js"></script>
<body ng-app="myApp" ng-controller="userCtrl">

<div class="w3-container">

<h3>Users</h3>

<table class="w3-table w3-bordered w3-striped">
  <tr>
    <th>Edit</th>
    <th>First Name</th>
    <th>Last Name</th>
  </tr>
  <tr ng-repeat="user in users">
    <td>
      <button class="w3-btn w3-ripple" ng-click="editUser(user.id)">&#9998; Edit</button>
    </td>
    <td>{{ user.fName }}</td>
    <td>{{ user.lName }}</td>
  </tr>
</table>
<br>
<button class="w3-btn w3-green w3-ripple" ng-click="editUser('new')">&#9998; Create New User</button>

<form ng-hide="hideform">
  <h3 ng-show="edit">Create New User:</h3>

JavaScript 代码

myUsers.js

angular.module('myApp', []).controller('userCtrl', function($scope) {
$scope.fName = '';

];
$scope.edit = true;
$scope.error = false;
$scope.incomplete = false;
$scope.hideform = true;
$scope.editUser = function(id) {
  $scope.hideform = false;
  if (id == 'new') {
    $scope.edit = true;
    $scope.incomplete = true;
    $scope.fName = '';
    $scope.lName = '';
    } else {
    $scope.edit = false;
    $scope.fName = $scope.users[id-1].fName;
    $scope.lName = $scope.users[id-1].lName;
  }
};

$scope.$watch('passw1',function() {$scope.test();});
$scope.$watch('passw2',function() {$scope.test();});
$scope.$watch('fName', function() {$scope.test();});
$scope.$watch('lName', function() {$scope.test();});

$scope.test = function() {
  if ($scope.passw1 !== $scope.passw2) {
    $scope.error = true;
    } else {
    $scope.error = false;
  }
  $scope.incomplete = false;
  if ($scope.edit && (!$scope.fName.length ||
