我正在尝试使用 Angular.js 和 Express.js 创建 Node.js 应用程序。
我正在做的是使用此代码将客户名称和地址添加到列表(随机)。
var mylist = new generic.list();
mylist.add({name:"Rohan",add:"Sec 49, Noida"});
mylist.add({name:"Sam",add:"Sec 63, Noida"});
mylist.add({name:"Jack",add:"Sec 15, Noida"});
现在我想在其中添加以下功能
Angular Controller - customerController to call an angular service
Angular Service - dataService - to call node js API (implemented earlier) using $http.
Angular View – customers.html - to display list of customers. Display the count of customers at the bottom of the SPA page.
我被困住了，请帮忙。如何从这一步开始。
最佳答案
查看一个有效的 Plnkr 示例: http://plnkr.co/edit/YevOesJ7Jhy4wpMWiQvE?p=preview ，或查看下面的代码。
这是你的 Controller
(function(){
var app = angular.module('myApp', []);
app.controller('CustomerController', CustomerController);
CustomerController.$inject = ["dataService"];
function CustomerController( dataService) {
var vm = this;
activate();
function activate() {
dataService.GetData()
.then(function(results) {
vm.data = results;
},
function(error) {})
.finally(function() {
});
}
}
})();
这是您的数据服务:您需要更改 HTTP 调用来访问 node.js API 而不是 list.json。
(function() {
'use strict';
angular.module('myApp')
.factory('dataService', dataService);
dataService.$inject = ['$q', '$timeout', '$http'];
function dataService($q, $timeout, $http) {
var data = [];
console.log("Number of table entries is: " + data.length);
var promise = $http.get('list.json');
promise.then(function(response) {
data = response.data;
console.log("Number of table entries is now: " + data.length);
});
return {
GetData: getData
};
function getData() {
return $q(function(resolve, reject) {
$timeout(function() {
resolve(data);
}, 3000);
});
}
}
})();
这是您的观点:
