代码由3块实现：
1.Ui
mvc5的解释就是定义项目，定义模块，定义基本视图
<body ng-app=‘routingDemoApp‘>
<div class="container">
<div class="row">
<h1 class="text-center">angular 单页新闻发布系统</h1>
</div>
<div class="row">
<div class="col-md-2">
<ul class="">
<li><a href="#/put">发布</a></li>
<li><a href="#/list">新闻列表</a></li>
</ul>
</div>
<div class="col-md-10" ng-view></div>
</div>
</div>
</body>
2.AnjularJs的功能实现
<script>
//配置路由器，绑定视图和控制器，细节看上面引用链接
var app = angular.module(‘routingDemoApp‘, [‘ngRoute‘]);
app.config([‘$routeProvider‘, function ($routeProvider) {
$routeProvider
.when(‘/‘, {
templateUrl: ‘list.html‘,
controller: ‘ListController‘
})
.when(‘/list‘, {
templateUrl: ‘list.html‘,
controller: ‘ListController‘
})
.when(‘/edit/:id‘, {
templateUrl: ‘edit.html‘,
controller: ‘EditController‘
})
.when(‘/del/:id‘, {
controller: ‘DelController‘,
templateUrl: ‘del.html‘,
})
.when(‘/detail/:id‘, {
templateUrl: ‘detail.html‘,
controller: ‘DetailController‘
})
.when(‘/put‘, {
templateUrl: ‘put.html‘,
controller: ‘PutController‘
})
.otherwise({ redirectTo: ‘/‘ });
}]);
//写控制器功能
app.controller("ListController", function ($scope, $http) {
$http.get("/AngularJS/data.ashx?action=getall")
.success(function (data) {
$scope.models = data.models;
})
});
app.controller("PutController", function ($scope, $http) {
$scope.addcontent = function () {
//这种写法很差，建议看下面EditController控制器里面用对象来写值
var data = "title=" + $scope.title + "&author=" + $scope.author + "&content=" + $scope.content;
$http.get("/AngularJS/data.ashx?action=add&" + data)
.success(function (data ) {
if (data == 1 && confirm("发布成功是否跳转")) location.href = "";
});
}
});
app.controller("EditController", function ($scope, $http, $routeParams) {
$scope.updata = function () {
//nnd，Jq用的 ("form").serialize(),只能拼接了；想用$http.get(url,congfig)的，但是值传不过去。。。
$scope.model.action = "up";
$http({ method: "get", url: "/AngularJS/data.ashx", params: $scope.model })
.success(function (data) {
if (data != 1) return false;
location.href = "";
});
};
$http.get("/AngularJS/data.ashx?action=get&id=" + $routeParams.id)
.success(function (data) {
$scope.model = data;
})
.error(function () {
alert("error");
$scope.formData = {};
});
});
app.controller("DelController", function ($scope, $http, $routeParams) {
$http.get("/AngularJS/data.ashx?action=del&id=" + $routeParams.id)
.success(function (data) {
if (data != 1) return false;
window.location.href("./");
})
.error(function (data) {
alert("error");
})
});
app.controller("DetailController", function ($scope, $http, $routeParams) {
$http.get("/AngularJS/data.ashx?action=get&id=" + $routeParams.id)
.success(function (data) {
$scope.model = data;
})
.error(function () {
alert("失败");
})
$scope.updata = function () {
$http.get("/AngularJS/data.ashx?action=up")
}
});
</script>
3.视图模板
<script type="text/ng-template" id="put.html">
<form class="form-horizontal">
<div class="form-group">
<label>标题</label>
<input type="text" class="form-control" ng-model="title" />
</div>
<div class="form-group">
<label>作者</label>
<input type="text" class="form-control" ng-model="author" />
</div>
<div class="form-group">
<label>内容</label>
<textarea type="text" class="form-control" ng-model="content"> </textarea>
</div>
<div class="form-group">
<input type="button" class="btn btn-success form-control" value="提交" ng-click="addcontent()"/>
</div>
</form>
</script>
<script type="text/ng-template" id="list.html">
<div class="row" >
<table class="table">
<thead>
<tr>
<th>编号</th>
<th>标题</th>
<th>时间</th>
<th>管理</th>
</tr>
</thead>
<tbody ng-repeat="x in models">
<tr>
<td>{{ $index+1 }}</td>
<td><a href="#/detail/{{x.Id}}"> {{ x.title }}</a></td>
<td>{{ x.time }}</td>
<td><a href="#/edit/{{x.Id}}">编辑</a>|<a href="#/del/{{x.Id}}">删除</a></td>
</tr>
</tbody>
</table>
</div>
</script>
<script type="text/ng-template" id="edit.html">
<form class="form-horizontal">
<input type="hidden" ng-model="model.Id"/>
<div class="form-group">
<label>标题</label>
<input type="text" class="form-control" ng-model="model.title" />
</div>
<div class="form-group">
<label>作者</label>
<input type="text" class="form-control" ng-model="model.author" />
</div>
<div class="form-group">
<label>内容</label>
<textarea type="text" class="form-control" ng-model="model.content"> </textarea>
</div>
<div class="form-group">
<input type="button" class="btn btn-success form-control" value="修改" ng-click="updata()"/>
</div>
</form>
</script>
<script type="text/ng-template" id="detail.html">
<h1 class="text-center">{{ model.title }}</h1>
<span class="text-center">作者：{{ model.author }},时间:{{ model.time }}</span>
<div>
{{ model.content }}
</div>
</script>
<script type="text/ng-template" id="del.html">
</script>
开发遇到以下几个问题：
1.Post提交的data数据是什么格式了？
JQ:$.post("url",data"")
Ang:$http.Post(data:"",params:"")
2.$scope.model获取前台传来的Json的取值问题
$http.get(url).success(function(data){
$scope.model = data;
})
json为集合：{"obj":[{id:1,name:"zzj"},{id:1,name:"zzj"}]},使用就是:$scope.model.obj[0].id,$scope.model.obj[0].name
json为对象：{id:1,name:"zzj"},使用的时候就是 $scope.model.id, $scope.model.name
3.路由器配置问题
http://www.runoob.com/angularjs/angularjs-routing.html
4.json转obj,string的细节（json检验网：http://www.bejson.com/）
json有2种：对象、集合
对象：{key:value,key:value}
集合:{object:[{key:value},{key:value}]}
格式之间的互转：
在Firefox，chrome，opera，safari，ie9，ie8等高级浏览器直接可以用JSON对象的stringify()和parse()方法。
JSON.stringify(obj)将JSON转为字符串。
JSON.parse(string)将字符串转为JSON格式；
Angular.fromJson( data );
Angular.toJson(data);
