在角度js中成功返回一个pervious方法后，有没有办法调用一个方法？ [英] Is there any way to call one method after a pervious method returned successfully in angular js?

问题描述

我有一些函数来获取数据并将数据发布到服务器但是由于角度js的异步性质，下一个方法在前一个返回之前开始执行，返回空字符串，它在下一个函数中使用...我已读过很多关于诺言的文章和$ q和非他们为我工作............



i希望功能执行的方式他们写的是有什么办法吗？请帮助......



我的代码完全在我的本地系统上运行，但它没有在服务器（云）上运行预期的方式



请帮助...



我尝试过的事情：

i have some functions to fetch data and to post data to server but due to asynchronous nature of angular js the next method start executing before the previous one returns which returns empty string it is used in next functions...i have read a lot articles about promise and $q and non of them worked for me............

i want the fuctions execute in the way they are written is there is any way? pls help......

my code runs on my local system perfectly but it is not running the expected way on Server(cloud)

pls help...

What I have tried:

app.factory('myService', function ($http) {
    return {
        // 1st function
        serverCall: function (purchaseid) {
            return $http.get('/po/poidsearchid/' + purchaseid).then(function (response) {
                console.log(response.data);
                console.log("Hi in server call");
                return response.data;
            });
        },
        // 2nd function
        anotherFunctionCall: function (poid) {
            //console.log("Hi in another call");
            $http.post('/po/poid', poid);
               console.log("Hi in another call");
            

        },

        // 3rd function
        anotherFunctionCall1: function (poiditems) {
           
            $http.post('/po/poiditems', poiditems)
                console.log("Hi in another call 1111");
                 
            

        },

        anotherFunctionCall2: function (purchaseid) {
            
            return $http.get('/po/poiditemssearchid/' + purchaseid).then(function (response) {
                console.log(response.data);
                console.log("Hi in another call 222");
                return response.data;
               
            });

        }

What I have tried:

app.factory('myService', function (

http）{
return {
// 第一个函数
serverCall： function （purchaseid）{
return

http) { return { // 1st function serverCall: function (purchaseid) { return

http.get（< span class =code-string>' / po / poidsearchid /' + purchaseid）.then（功能（响应）{
console .log（re sponse.data）;
console .log（ 在服务器中你好称之为）;
return response.data;
}）;
}，
// 第二个函数
anotherFunctionCall： function （poid）{
// console.log （你好，在另一个电话中）;

http.get('/po/poidsearchid/' + purchaseid).then(function (response) { console.log(response.data); console.log("Hi in server call"); return response.data; }); }, // 2nd function anotherFunctionCall: function (poid) { //console.log("Hi in another call");
