好久没有写过东西了,感受写东西都不知道从哪里开始了,如今仍是先写点技术性的吧,angularjs--我兄弟把它叫成“俺哥啦js”javascript
官方网址:https://angularjs.org/ CDN:https://ajax.googleapis.com/ajax/libs/angularjs/1.3.0-beta.5/angular.min.js
决定了angularjs的做用域范围,你能够以下使用html
<html ng-app> … </html>
来让angularjs渲染整个页面,也可使用java
<div ng-app='myapp'> …… </div>
来渲染其中的一部分。angularjs
ng-model,当你的数据模型被改变的时候,譬如ng-model='test',其中这个test的数值被改变的时候,{{test}}的数值也将跟随改变,也就是链接到ng-model中的test也跟随改变,以下ajax
<!doctype html> <html> <head> <script src="angular.min.js" type="text/javascript"></script> <title>learing argularjs--widuu</title> </head> <body ng-app> <input ng-model='test' >{{test}} </body> </html>
这个主要是作模块的注册,建立和索引,譬如咱们ng-app想把这个注册成为一个服务就要用,当咱们引用索引一个模块的时候也要使用api
angular.module(name, [requires], [configFn]); #name 类型string建立的检索模块的名称 #requires 简单理解就是你须要包含的使用模块,譬如ngRoute路由模块 #configFn 能够选配的功能模块,功能和module.config相似
controller是angular.Module中的方法controller(name, constructor);其中name是controller的名字,constructor是控制器构造函数,咱们利用一段代码来讲明服务器
<!doctype html> <html> <head> <script src="angular.min.js" type="text/javascript"></script> <script type="text/javascript"> var app = angular.module('myapp',[]); app.controller('mytest',function($scope){ $scope.test="hello word"; }); </script> <title>learing argularjs--widuu</title> </head> <body ng-app='myapp' ng-controller='mytest' > <input ng-model='test'>{{test}} </body> </html>
value也是angular.Module中的方法value(name, object);其中name是service的名称,object是服务器实例对象,这个时候咱们就能够把上边的代码修改正成这样网络
<!doctype html> <html> <head> <script src="angular.min.js" type="text/javascript"></script> <script type="text/javascript"> var app = angular.module('myapp',[]) .value('testvalue','word'); app.controller('mytest',function($scope,testvalue){ $scope.test="hello "+ testvalue; }); </script> <title>learing argularjs--widuu</title> </head> <body ng-app='myapp' ng-controller='mytest' > <input ng-model='test'>{{test}} </body> </html>
factory也是angular.Module中的方法factory(name, providerFunction);;其中name是service的名称,providerFunction是函数用于建立新的服务器对象,这个时候咱们就能够把上边的代码修改正成这样app
<!doctype html> <html> <head> <script src="angular.min.js" type="text/javascript"></script> <script type="text/javascript"> var app = angular.module('myapp',[]) .value('testvalue','widuu') .factory('testfactory',function(testvalue){ return{ lable:function(){ return "this can output : hello "+ testvalue; } } }); app.controller('mytest',function($scope,testvalue,testfactory){ $scope.test = "hello "+ testvalue; $scope.output = testfactory.lable(); }); </script> <title>learing argularjs--widuu</title> </head> <body ng-app='myapp' ng-controller='mytest' > <input ng-model='test'>{{test}} </p> {{output}} </body> </html>
provider也是angular.Module中的方法provider(name, providerType);其中name是service的名称,providerFunction是函数用于建立新的服务器对象,这个跟factory差很少,咱们如今用provider重写ide
<!doctype html> <html> <head> <script src="angular.min.js" type="text/javascript"></script> <script type="text/javascript"> var app = angular.module('myapp',[]) .value('testvalue','widuu') .provider('testprovider', function(){ this.lable = "this will output : hello widuu"; this.$get = function () { return this; } } ); app.controller('mytest',function($scope,testvalue,testprovider){ $scope.test = "hello "+ testvalue; $scope.output = testprovider.lable; }); </script> <title>learing argularjs--widuu</title> </head> <body ng-app='myapp' ng-controller='mytest' > <input ng-model='test'>{{test}} </p> {{output}} </body> </html>
service也是angular.Module中的方法service(name, constructor);其中name是service的名称,constructor一个将被实例化的构造函数,这个跟factory差很少,咱们如今用service重写
<!doctype html> <html> <head> <script src="angular.min.js" type="text/javascript"></script> <script type="text/javascript"> var app = angular.module('myapp',[]) .value('testvalue','widuu') .service('testservice', function(testvalue){ this.lable = function(){ return "this will output:hello "+testvalue; } } ); app.controller('mytest',function($scope,testvalue,testservice){ $scope.test = "hello "+ testvalue; $scope.output = testservice.lable(); }); </script> <title>learing argularjs--widuu</title> </head> <body ng-app='myapp' ng-controller='mytest' > <input ng-model='test'>{{test}} </p> {{output}} </body> </html>
constant也是angular.Module中的方法constant(name, object);其中name是常量的名称,而object是常量的值,咱们能够这样写的
<!doctype html> <html> <head> <script src="angular.min.js" type="text/javascript"></script> <script type="text/javascript"> var app = angular.module('myapp',[]) .value('testvalue','widuu') .constant('count',23) .service('testservice', function(testvalue,count){ this.lable = function(){ return "this will output:hello "+testvalue+",age is "+count; } } ); app.controller('mytest',function($scope,testvalue,testservice){ $scope.test = "hello "+ testvalue; $scope.output = testservice.lable(); }); </script> <title>learing argularjs--widuu</title> </head> <body ng-app='myapp' ng-controller='mytest' > <input ng-model='test'>{{test}} </p> {{output}} </body> </html>
