单项绑定的前缀标识符
使用方法：在元素中使用属性，好比这样<div my-directive my-name="{{name}}"></div>，注意，属性的名字要用-将两个单词连接，因为是数据的单项绑定所以要通过使用{{}}来绑定数据。
=
双向数据绑定前缀标识符
使用方法：在元素中使用属性，好比这样<div my-directive age="age"></div>,注意，数据的双向绑定要通过=前缀标识符实现，所以不可以使用{{}}。
<
单项绑定的前缀标识符，和=使用类似。不同的是改变内部scope不会反映到parent的scope
使用方法：在元素中使用属性，好比这样<my-component my-attr="parentModel">,directive的定义scope: { localModel:‘<myAttr‘ }。代码
&
绑定函数方法的前缀标识符
使用方法：在元素中使用属性，好比这样<div my-directive change-my-age="changeAge()"></div>，注意，属性的名字要用-将多个个单词连接。m.directive(‘hdCms‘, [function () {
return {
restrict: ‘E‘,
replace: true,
templateUrl: ‘../view/57.html‘,
controller: [‘$scope‘, function ($scope) {
$scope.data = [
{id: 1, name: ‘后盾人‘},
{id: 1, name: ‘hdcms‘},
{id: 1, name: ‘hdphp‘}
];
}]
}
}]); $scope.getClientHeight=function(){
$scope.clientHeight = $window.document.body.clientHeight;
}
$scope.getScrollHeight=function(){
$scope.scrollHeight = $window.document.body.scrollHeight;
}
$scope.prompt=function(){
$scope.content = $window.prompt(‘请输入内容‘);
}m.controller(‘ctrl1‘, [‘$scope‘, ‘$cacheFactory‘, function ($scope, $cacheFactory) {
var obj = $cacheFactory(‘hdphp‘);
//sessionStorage localStorage
obj.put(‘web‘, {name: ‘后盾人‘, url: ‘houdunren.com‘});
obj.put(‘user‘, {name: ‘向军‘, mail: ‘2300071698@qq.com‘});
$scope.data = obj.get(‘web‘).name;
//删除缓存数据
// obj.remove(‘web‘);
// obj.removeAll();
// obj.destroy();
// console.log(obj.get(‘web‘));
// console.log(obj.get(‘user‘));
}]);
m.controller(‘ctrl2‘, [‘$scope‘, ‘$cacheFactory‘, function ($scope, $cacheFactory) {
var obj = $cacheFactory.get(‘hdphp‘);
$scope.data = obj.get(‘web‘).name;
}]);m.controller(‘ctrl‘, [‘$scope‘, ‘$http‘, function ($scope, $http) {
$http({
method:‘get‘,
url:‘1.php‘

//成功时执行

$scope.data = response.data;
},function(response){
//失败时执行 hdphp
console.log(response);

}]);dao层：就是Model层，在后台时，这一层的作用，就要是写与数据库交互数据的一层，在angularJS里就主要是写ajax的。
service层：主查写逻辑代码的，但在angularJS里也可以持久化数据（充当数据容器），以供不同的controller高用。
controller层：即控制层，在angularJS里就是写控制器的。控制器里尽量不要写那些不必要的逻辑，尽量写在service层里。
所以，就有了创建自定义服务的三种方式。
var app = angular.module(‘myApp‘, []);
app.factory(‘myFactory‘, function($http,$q) {
var service = {};
service.name = "张三";
//请求数据
service.getData = function(){
var d = $q.defer();
$http.get("url")//读取数据的函数。
.success(function(response) {
d.resolve(response);
})
.error(function(){
d.reject("error");
});
return d.promise;
}
return service;
});
app.controller(‘myCtrl‘, function($scope, myFactory) {
//alert(myFactory.name);
myFactory.getData().then(function(data){
console.log(data);//正确时走这儿
},function(data){
alert(data)//错误时走这儿
});;
});<div ng-app="myApp" ng-controller="myCtrl">
<h1>{{r}}</h1>
</div>
<script>
var app = angular.module(‘myApp‘, []);
app.service(‘myService‘, function($http,$q) {
this.name = "service";
this.myFunc = function (x) {
return x.toString(16);//转16进制
}
this.getData = function(){
var d = $q.defer();
$http.get("ursl")//读取数据的函数。
.success(function(response) {
d.resolve(response);
})
.error(function(){
alert(0)
d.reject("error");
});
return d.promise;
}
});
app.controller(‘myCtrl‘, function($scope, myService) {
$scope.r = myService.myFunc(255);
myService.getData().then(function(data){
console.log(data);//正确时走这儿
},function(data){
alert(data)//错误时走这儿
});
});
