首先从angular.js的目录开始，如下图，知道了我们要学什么，然后再开始有目的的学习与对比。
1、从表达式开始：
ng-app指令初始化一个 AngularJS 应用程序。
ng-init指令初始化应用程序数据。
2、指令
<div ng-app="" ng-init="msgs=[
{name:'张三',sex:'男'},
{name:'李四',sex:'女'},
{name:'王五',sex:'男'}]">
<p>所有对象：</p>
<ul>
<li ng-repeat="x in msgs">
{{ x.name + ', ' + x.sex}}
</li>
</ul>
</div>
ng-repeat指令对于集合中（数组中）的每个项会克隆一次 HTML元素。
3、模型
4、$scope作用域
5、控制器
6、过滤器
。。。
7、表单
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<title></title>
<meta charset="utf-8" />
<script src="angular.min.js"></script>
</head>
<body>
<div ng-app="myApp" ng-controller="formController">
<form novalidate>
First Name:<br>
<input type="text" ng-model="user.firstName"><br>
Last Name:<br>
<input type="text" ng-model="user.lastName">
<br><br>
<button ng-click="reset()">RESET</button>
</form>
<p>form = {{user}}</p>
<p>master = {{master}}</p>
</div> <script>
var app = angular.module('myApp', []);
app.controller('formController', function ($scope) {
$scope.master = {firstName: "果果", lastName: "糖糖"};
$scope.reset = function() {
$scope.user = angular.copy($scope.master);
};
$scope.reset();
});
</script>
</body>
</html>
ng-app指令定义了 AngularJS 应用。
ng-controller 指令定义了应用控制器。
ng-model 指令绑定了两个 input 元素到模型的 user 对象。
formCtrl 函数设置了 master 对象的初始值，并定义了 reset() 方法。
reset() 方法设置了 user 对象等于 master 对象。
ng-click 指令调用了 reset() 方法，且在点击按钮时调用。
novalidate 属性在应用中不是必须的，但是你需要在 AngularJS 表单中使用，用于重写标准的 HTML5 验证。
8、输入验证
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<title></title>
<meta charset="utf-8" />
<script src="angular.min.js"></script>
</head>
<body>
<h2>验证demo</h2>
<form ng-app="myApp" ng-controller="validateCtrl" name="myForm" novalidate>
<p>
用户名:<br>
<input type="text" name="user" ng-model="user" required>
<span style="color:black" ng-show="myForm.user.$dirty && myForm.user.$invalid">
<span ng-show="myForm.user.$error.required">用户名非空</span>
</span>
</p> <p>
邮箱:<br>
<input type="email" name="email" ng-model="email" required>
<span style="color:black" ng-show="myForm.email.$dirty && myForm.email.$invalid">
<span ng-show="myForm.email.$error.required">邮箱非空</span>
<span ng-show="myForm.email.$error.email">请输入正确格式的邮箱</span>
</span>
</p> <p>
<input type="submit"ng-disabled="myForm.user.$dirty && myForm.user.$invalid || myForm.email.$dirty && myForm.email.$invalid">
</p>
</form> <script>
var app = angular.module('myApp', []);
app.controller('validateCtrl', function($scope) {
$scope.user = '果果';
$scope.email = 'dulalay@163.com';
});
</script>
</body>
</html>
展示如下：
HTML 表单属性novalidate用于禁用浏览器默认的验证。
9、Boostrap
<!DOCTYPE html>
<html>
<link href="bootstrap.min.css" rel="stylesheet" />
<script src="angular.min.js"></script>
<body ng-app="myApp" ng-controller="userCtrl">
<div class="container">
<h3>表格显示Boostrap和Angular.JS的使用</h3>
<table class="table table-striped">
<thead>
<tr>
<th>编辑</th>
<th>名</th>
<th>姓</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="user in users">
<td>
<button class="btn" ng-click="editUser(user.id)">
<span class="glyphicon glyphicon-pencil"></span> 编辑
</button>
</td>
<td>{{ user.fName }}</td>
<td>{{ user.lName }}</td>
</tr>
</tbody>
</table> <hr>
<button class="btn btn-success" ng-click="editUser('new')">
<span class="glyphicon glyphicon-user"></span> 新建用户
</button>
<hr> <h3 ng-show="edit">新建用户</h3>
<h3 ng-hide="edit">编辑用户</h3> <form class="form-horizontal">

</div>
</div>
</form> <hr>
<button class="btn btn-success" ng-disabled="error || incomplete">
<span class="glyphicon glyphicon-save"></span> 保存
</button>
</div>
<script src="angularDemo.js"></script>
</body>
</html>

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

}
};
});
