決定了angularjs的做用域範圍,你能夠以下使用:javascript
<html ng-app>
…
</html>
來讓angularjs渲染整個頁面,也可使用html
<div ng-app='myapp'>
……
</div>
來渲染其中的一部分。java
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angularjs
<!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服務器
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app
<!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){
$scope.test="hello word";
});
</script>
<title>learing argularjs--widuu</title>
</head>
<body ng-app='myapp' ng-controller='mytest' >
<input ng-model='test'>{{test}}
</body>
</html>
value也是angular.Module中的方法value(name, object);其中name是service的名稱,object是服務器實例對象,這個時候咱們就能夠把上邊的代碼修改正成這樣ide
<!doctype html>
<html>
<head>
<script src="angular.min.js" type="text/javascript"></script>
<script type="text/javascript">
var app = angular.module('myapp',[])
.value('testvalue','word');
app.controller('mytest',function($scope,testvalue){
$scope.test="hello "+ testvalue;
});
</script>
<title>learing argularjs--widuu</title>
</head>
<body ng-app='myapp' ng-controller='mytest' >
<input ng-model='test'>{{test}}
</body>
</html>
factory也是angular.Module中的方法factory(name, providerFunction);;其中name是service的名稱,providerFunction是函數用於建立新的服務器對象,這個時候咱們就能夠把上邊的代碼修改正成這樣函數
複製代碼 代碼以下:ui
<!doctype html>
<html>
<head>
<script src="angular.min.js" type="text/javascript"></script>
<script type="text/javascript">
var app = angular.module('myapp',[])
.value('testvalue','widuu')
.factory('testfactory',function(testvalue){
return{
lable:function(){
return "this can output : hello "+ testvalue;
}
}
});
app.controller('mytest',function($scope,testvalue,testfactory){
$scope.test = "hello "+ testvalue;
$scope.output = testfactory.lable();
});
</script>
<title>learing argularjs--widuu</title>
</head>
<body ng-app='myapp' ng-controller='mytest' >
<input ng-model='test'>{{test}}
</p>
{{output}}
</body>
</html>
provider也是angular.Module中的方法provider(name, providerType);其中name是service的名稱,providerFunction是函數用於建立新的服務器對象,這個跟factory差很少,咱們如今用provider重寫this
複製代碼 代碼以下:
<!doctype html>
<html>
<head>
<script src="angular.min.js" type="text/javascript"></script>
<script type="text/javascript">
var app = angular.module('myapp',[])
.value('testvalue','widuu')
.provider('testprovider',
function(){
this.lable = "this will output : hello widuu";
this.$get = function () {
return this;
}
}
);
app.controller('mytest',function($scope,testvalue,testprovider){
$scope.test = "hello "+ testvalue;
$scope.output = testprovider.lable;
});
</script>
<title>learing argularjs--widuu</title>
</head>
<body ng-app='myapp' ng-controller='mytest' >
<input ng-model='test'>{{test}}
</p>
{{output}}
</body>
</html>
service也是angular.Module中的方法service(name, constructor);其中name是service的名稱,constructor一個將被實例化的構造函數,這個跟factory差很少,咱們如今用service重寫
複製代碼 代碼以下:
<!doctype html>
<html>
<head>
<script src="angular.min.js" type="text/javascript"></script>
<script type="text/javascript">
var app = angular.module('myapp',[])
.value('testvalue','widuu')
.service('testservice',
function(testvalue){
this.lable = function(){
return "this will output:hello "+testvalue;
}
}
);
app.controller('mytest',function($scope,testvalue,testservice){
$scope.test = "hello "+ testvalue;
$scope.output = testservice.lable();
});
</script>
<title>learing argularjs--widuu</title>
</head>
<body ng-app='myapp' ng-controller='mytest' >
<input ng-model='test'>{{test}}
</p>
{{output}}
</body>
</html>
constant也是angular.Module中的方法constant(name, object);其中name是常量的名稱,而object是常量的值,咱們能夠這樣寫的
複製代碼 代碼以下:
<!doctype html><html> <head> <script src="angular.min.js" type="text/javascript"></script> <script type="text/javascript"> var app = angular.module('myapp',[]) .value('testvalue','widuu') .constant('count',23) .service('testservice', function(testvalue,count){ this.lable = function(){ return "this will output:hello "+testvalue+",age is "+count; } } ); app.controller('mytest',function($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>
