决定了angularjs的做用域范围,你能够以下使用:javascript
<html ng-app>
…
</html>
来让angularjs渲染整个页面,也可使用html
<div ng-app='myapp'>
……
</div>
来渲染其中的一部分。java
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>
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服务器
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){
$scope.test="hello "+ testvalue;
});
</script>
<title>learing argularjs--widuu</title>
</head>
<body ng-app='myapp' ng-controller='mytest' >
<input ng-model='test'>{{test}}
</body>
</html>
factory也是angular.Module中的方法factory(name, providerFunction);;其中name是service的名称,providerFunction是函数用于建立新的服务器对象,这个时候咱们就能够把上边的代码修改正成这样函数
复制代码 代码以下:ui
<!doctype html>
<html>
<head>
<script src="angular.min.js" type="text/javascript"></script>
<script type="text/javascript">
var app = angular.module('myapp',[])
.value('testvalue','widuu')
.factory('testfactory',function(testvalue){
return{
lable:function(){
return "this can output : hello "+ testvalue;
}
}
});
app.controller('mytest',function($scope,testvalue,testfactory){
$scope.test = "hello "+ testvalue;
$scope.output = testfactory.lable();
});
</script>
<title>learing argularjs--widuu</title>
</head>
<body ng-app='myapp' ng-controller='mytest' >
<input ng-model='test'>{{test}}
</p>
{{output}}
</body>
</html>
provider也是angular.Module中的方法provider(name, providerType);其中name是service的名称,providerFunction是函数用于建立新的服务器对象,这个跟factory差很少,咱们如今用provider重写this
复制代码 代码以下:
<!doctype html>
<html>
<head>
<script src="angular.min.js" type="text/javascript"></script>
<script type="text/javascript">
var app = angular.module('myapp',[])
.value('testvalue','widuu')
.provider('testprovider',
function(){
this.lable = "this will output : hello widuu";
this.$get = function () {
return this;
}
}
);
app.controller('mytest',function($scope,testvalue,testprovider){
$scope.test = "hello "+ testvalue;
$scope.output = testprovider.lable;
});
</script>
<title>learing argularjs--widuu</title>
</head>
<body ng-app='myapp' ng-controller='mytest' >
<input ng-model='test'>{{test}}
</p>
{{output}}
</body>
</html>
service也是angular.Module中的方法service(name, constructor);其中name是service的名称,constructor一个将被实例化的构造函数,这个跟factory差很少,咱们如今用service重写
复制代码 代码以下:
<!doctype html>
<html>
<head>
<script src="angular.min.js" type="text/javascript"></script>
<script type="text/javascript">
var app = angular.module('myapp',[])
.value('testvalue','widuu')
.service('testservice',
function(testvalue){
this.lable = function(){
return "this will output:hello "+testvalue;
}
}
);
app.controller('mytest',function($scope,testvalue,testservice){
$scope.test = "hello "+ testvalue;
$scope.output = testservice.lable();
});
</script>
<title>learing argularjs--widuu</title>
</head>
<body ng-app='myapp' ng-controller='mytest' >
<input ng-model='test'>{{test}}
</p>
{{output}}
</body>
</html>
constant也是angular.Module中的方法constant(name, object);其中name是常量的名称,而object是常量的值,咱们能够这样写的
复制代码 代码以下:
<!doctype html><html> <head> <script src="angular.min.js" type="text/javascript"></script> <script type="text/javascript"> var app = angular.module('myapp',[]) .value('testvalue','widuu') .constant('count',23) .service('testservice', function(testvalue,count){ this.lable = function(){ return "this will output:hello "+testvalue+",age is "+count; } } ); app.controller('mytest',function($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>
