我正在使用 angular 5 的WEB银行应用程序工作。任务是我想找出计算机的设备 ID 和浏览器名称。

我试过这个 NPM 模块：

npm install ngx-device-detector --save

import { NgModule } from '@angular/core';
  import { DeviceDetectorModule } from 'ngx-device-detector';
  ...
  @NgModule({
    declarations: [
      ...
      LoginComponent,
      SignupComponent
      ...
    ],
    imports: [
      CommonModule,
      FormsModule,
      DeviceDetectorModule.forRoot()
    ],
    providers:[
      AuthService
    ]
    ...
  })

import { Component } from '@angular/core';
  ...
  import { DeviceDetectorService } from 'ngx-device-detector';
  ...
  @Component({
    selector: 'home',  // <home></home>
    styleUrls: [ './home.component.scss' ],
    templateUrl: './home.component.html',
    ...
  })

  export class HomeComponent {
    deviceInfo = …

请看一下这种方法.在这个函数响应中,我调用了两个函数findConnectedUsersRelationship()和displayUsers(response.users).

问题是displayUsers(response.users)方法运行并获得结果findConnectedUsersRelationship().我的要求是我需要先跑findConnectedUsersRelationship()第二个displayUsers(response.users).第二种方法取决于第一种方法.

function filterUsers(location, gender, youngAge, oldAge, interests){
        var userId = signedUserId;
        $.post(urlHolder.filter, {
            userId: userId,
            location: location,
            gender: gender,
            youngAge: youngAge,
            oldAge: oldAge,
            interests: interests
        }, function(response) {
            console.log('User response <<>>', response.users.length);
            var filteredUsers;
            findConnectedUsersRelationship();
            displayUsers(response.users);

        });
    }



// To find connected user relationship
var relationshipList = new Array;
function findConnectedUsersRelationship() {
    try {
        $.post(urlHolder.findConnectedUsersRelationship, {
            userId : signedUserId
        }, function(response) {
            //console.log('response downforanything: ', JSON.stringify(response));
            if …
