AngularJS
▌Introduction
When
things become complicated in the front end, we will try to organize our
javascripts for reusing, sharing and maintainability.
In
AngularJS, we can use $rootScope or Services , such like Service
and factory, to achieve the above goals.
▌Environment
l AngularJS v1.4.8
▌Samples
▋$rootScope
Explanation
from AngularJS Documents :
Every
application has a single root scope. All other scopes are descendant scopes
of the root scope.
|
Sample
Codes
l root-scope.js
var app =
angular.module('app')
.run(function ($rootScope) {
$rootScope.WebSiteName = "MyWebSite";
});
|
l my-controller.js
var app =
angular.module('app', [])
.controller('RegisterCtrl', function ($scope,$rootScope) {
var redirectUrl = window.location.origin + "/" + $rootScope.WebSiteName + "/Authentication/User";
});
|
▋Service
l customer-service.js
var contactapp =
angular.module('customerapp', []).
service('CustomerService', function ($http) {
var GetAllCustomers = function () {
return $http.get(getUri).error(function (status, headers,
config) {
console.log(status, headers,
config);
}).then(function (response) {
return response;
}).catch(function (e) {
throw e;
});
};
return GetAllCustomers;
});
|
l my-controller.js
var app =
angular.module('app', ['customerapp'])
.controller('CustomerCreateCtrl', function ($scope, CustomerService) {
var getPromise = CustomerService(); //For service
getPromise.then(function (response) {
angular.forEach(response.data, function (item) {
var option = {};
option.CustomerId =
item.CustomerId;
option.isEnabled = true;
$scope.CustomerOptions.push(option);
});
}).catch(function (e) {
swal("無法查詢所有客戶資訊，請稍後嘗試!", "", "error");
})
});
|
▋Factory
var contactapp =
angular.module('customerapp',[])
.factory('CustomerFactory', function ($http) {
var factory = {};
factory.KeyWords = 'Key words';
factory.GetAllAvailableCustomer =
function () {
//return somthing
};
//Get
factory.GetCustomer =
function (inChargeId) {
//return somthing
};
//Create
factory.CreateCustomer =
function (entity) {
//return somthing
};
return factory;
});
|
var app =
angular.module('app', ['customerapp'])
.controller('CustomerCreateCtrl', function ($scope, CustomerFacory) {
CustomerFactory.GetAllAvailableCustomer();
//For
factory
$scope.KeyWords = CustomerFactory.KeyWords;
});
