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 = "";
                        });
                }
            });

                    //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 = "";
                    });
                };

                    alert("error");

                });


            });

            <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>

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);
