angularJs service
有关angular service初步学习笔记：首先，要把service对象作为参数传给controller
var app = angular.module('myApp', []);
app.controller('customersCtrl', function($scope, $location) {
$scope.myUrl = $location.absUrl();
});
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope, $http) {
$http.get("welcome.htm").then(function (response) {
$scope.myWelcome = response.data;
});
});
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope, $http) {
$http.get("welcome.htm").then(function (response) {
$scope.myWelcome = response.data;
});
});
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope, $http) {
$http.get("welcome.htm").then(function (response) {
$scope.myWelcome = response.data;
});
});

<p>255 的16进制是:</p>
<h1>{{hex}}</h1>
</div>
<p>自定义服务，用于转换16进制数：</p>
<script>
var app = angular.module('myApp', []);
app.service('hexafy', function() {
this.myFunc = function (x) {
return x.toString(16);
}
});
app.controller('myCtrl', function($scope, hexafy) {
$scope.hex = hexafy.myFunc(255);
});
</script>
</body>
</html>
当你创建了自定义服务，并连接到你的应用上后，你可以在控制器，指令，过滤器或其他服务中使用它。
在过滤器 myFormat 中使用服务 hexafy:
return function(x) {
return hexafy.myFunc(x);
};
}]);

<div ng-app="myApp" ng-controller="myCtrl">
<p>现在时间是:</p>
<h1>{{theTime}}</h1>
</div>
<p>上述代码是不使用 $interval 服务的情况下，运用 $apply，实现每一秒显示信息的功能。</p>
<script>
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.theTime = new Date().toLocaleTimeString();
$scope.setTime = function() {
// $apply 方法可以修改数据
$scope.$apply(function() {
$scope.theTime = new Date().toLocaleTimeString();
});
};
setInterval($scope.setTime, 1000);
});

$scope.$watch('firstName', function() {
