好久沒有寫過東西了,感受寫東西都不知道從哪裏開始了,如今仍是先寫點技術性的吧,angularjs--我兄弟把它叫成「俺哥啦js」javascript
官方網址:https://angularjs.org/ CDN:https://ajax.googleapis.com/ajax/libs/angularjs/1.3.0-beta.5/angular.min.js
決定了angularjs的做用域範圍,你能夠以下使用html
<html ng-app> … </html>
來讓angularjs渲染整個頁面,也可使用java
<div ng-app='myapp'> …… </div>
來渲染其中的一部分。angularjs
ng-model,當你的數據模型被改變的時候,譬如ng-model='test',其中這個test的數值被改變的時候,{{test}}的數值也將跟隨改變,也就是鏈接到ng-model中的test也跟隨改變,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>
這個主要是作模塊的註冊,建立和索引,譬如咱們ng-app想把這個註冊成爲一個服務就要用,當咱們引用索引一個模塊的時候也要使用api
angular.module(name, [requires], [configFn]); #name 類型string建立的檢索模塊的名稱 #requires 簡單理解就是你須要包含的使用模塊,譬如ngRoute路由模塊 #configFn 能夠選配的功能模塊,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是控制器構造函數,咱們利用一段代碼來講明服務器
<!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){ $scope.test="hello word"; }); </script> <title>learing argularjs--widuu</title> </head> <body ng-app='myapp' ng-controller='mytest' > <input ng-model='test'>{{test}} </body> </html>
value也是angular.Module中的方法value(name, object);其中name是service的名稱,object是服務器實例對象,這個時候咱們就能夠把上邊的代碼修改正成這樣網絡
<!doctype html> <html> <head> <script src="angular.min.js" type="text/javascript"></script> <script type="text/javascript"> var app = angular.module('myapp',[]) .value('testvalue','word'); app.controller('mytest',function($scope,testvalue){ $scope.test="hello "+ testvalue; }); </script> <title>learing argularjs--widuu</title> </head> <body ng-app='myapp' ng-controller='mytest' > <input ng-model='test'>{{test}} </body> </html>
factory也是angular.Module中的方法factory(name, providerFunction);;其中name是service的名稱,providerFunction是函數用於建立新的服務器對象,這個時候咱們就能夠把上邊的代碼修改正成這樣app
<!doctype html> <html> <head> <script src="angular.min.js" type="text/javascript"></script> <script type="text/javascript"> var app = angular.module('myapp',[]) .value('testvalue','widuu') .factory('testfactory',function(testvalue){ return{ lable:function(){ return "this can output : hello "+ testvalue; } } }); app.controller('mytest',function($scope,testvalue,testfactory){ $scope.test = "hello "+ testvalue; $scope.output = testfactory.lable(); }); </script> <title>learing argularjs--widuu</title> </head> <body ng-app='myapp' ng-controller='mytest' > <input ng-model='test'>{{test}} </p> {{output}} </body> </html>
provider也是angular.Module中的方法provider(name, providerType);其中name是service的名稱,providerFunction是函數用於建立新的服務器對象,這個跟factory差很少,咱們如今用provider重寫ide
<!doctype html> <html> <head> <script src="angular.min.js" type="text/javascript"></script> <script type="text/javascript"> var app = angular.module('myapp',[]) .value('testvalue','widuu') .provider('testprovider', function(){ this.lable = "this will output : hello widuu"; this.$get = function () { return this; } } ); app.controller('mytest',function($scope,testvalue,testprovider){ $scope.test = "hello "+ testvalue; $scope.output = testprovider.lable; }); </script> <title>learing argularjs--widuu</title> </head> <body ng-app='myapp' ng-controller='mytest' > <input ng-model='test'>{{test}} </p> {{output}} </body> </html>
service也是angular.Module中的方法service(name, constructor);其中name是service的名稱,constructor一個將被實例化的構造函數,這個跟factory差很少,咱們如今用service重寫
<!doctype html> <html> <head> <script src="angular.min.js" type="text/javascript"></script> <script type="text/javascript"> var app = angular.module('myapp',[]) .value('testvalue','widuu') .service('testservice', function(testvalue){ this.lable = function(){ return "this will output:hello "+testvalue; } } ); app.controller('mytest',function($scope,testvalue,testservice){ $scope.test = "hello "+ testvalue; $scope.output = testservice.lable(); }); </script> <title>learing argularjs--widuu</title> </head> <body ng-app='myapp' ng-controller='mytest' > <input ng-model='test'>{{test}} </p> {{output}} </body> </html>
constant也是angular.Module中的方法constant(name, object);其中name是常量的名稱,而object是常量的值,咱們能夠這樣寫的
<!doctype html> <html> <head> <script src="angular.min.js" type="text/javascript"></script> <script type="text/javascript"> var app = angular.module('myapp',[]) .value('testvalue','widuu') .constant('count',23) .service('testservice', function(testvalue,count){ this.lable = function(){ return "this will output:hello "+testvalue+",age is "+count; } } ); app.controller('mytest',function($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>
