AngularJS过滤：

AngularJS过滤器允许我们格式化数据以在UI上显示而不改变原始格式。

格式:

一些比较重要的过滤器：

Number

Filter

orderBy：

查询的条件就是根据下拉框来进行过滤的

AngularJS模块：

AngularJS应用程序必须创建一个顶级应用程序模块。

创建应用程序模块

创建控制器模块

AngularJS形式：

AngularJS表单并提交数据。

<head ng-app="studentApp">

    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

    <title>First AngularJS Application</title>

    <meta charset="utf-8" />

    <script src="Scripts/jquery-1.9.1.min.js"></script>

    <script src="Scripts/angular.min.js"></script>

</head>

<body ng-controller="studentController">

    <h1>学生信息：</h1>

    <form  ng-form="submitStudnetForm()">

            //1.创建模块

            var studentApp = angular.module('studentApp', []);

            studentApp.controller("studentController", function ($scope, $http, $log) {

                //3. 附加originalStudent类  这个类

                $scope.originalStudent = {

                $scope.student = angular.copy($scope.originalStudent);

                //5.当你点提交的时候触发这个事件

                $scope.submitStudnetForm = function () {
