Question

在这里，我正在从组件中获取复选框列表

<div class="checkbox" *ngFor="let m of modelupdatecurrencycheckbox">
    <input class="form-check-input"
        (change)="updatecurrencyselect(m.name)"
        [(ngModel)]="m.checked" name="{{ modelupdatecurrencycheckbox.name }}"
        type="checkbox" id="{{m.name}}"
        [ngModelOptions]="{standalone: true}">

    <label class="form-check-label" for="{{m.name}}">
        {{m.name}}
    </label>
</div>

<div class="container">
    <button type="button" class="btn btn-primary waves-effect" (click)="onSubmitupdatecurrencyCheckbox()">SAVE</button>
</div>

<input type="text" [(ngModel)]="added">
<button class="btn btn-primary" (click)="addedinput()">add</button>

数组正在推送，但数组未发布：

added:any=""
updatecurrencycheckbox:any={ tablename:"updatecurrency" };
modelupdatecurrencycheckbox = [
    {
        name: 'INR  ',
        checked: false,
    },{
        name: 'USD  ',
        checked: false
    },{
        name: 'Euro  ',
        checked: false,
    },{
        datasas:[]
    }];

addedinput(){

    this.datasas = this.modelupdatecurrencycheckbox
            .push(
                {
                    name: this.added,
                    checked: false
                });
              console.log("sda" + JSON.stringify(datasas))
}

onSubmitupdatecurrencyCheckbox(){
    var data = {
        array:this.modelordercurrencycheckbox,
        tablename:"updatecurrency"
    }

    this.dataService.postcustomertablepreferences(data).subscribe(
        (response) => console.log(response),
        (error) => console.log(error)
    );
}

使用API URL在MongoDB中发布数据的服务：

import {Injectable} from '@angular/core'
import {Http, URLSearchParams, RequestOptions, Response, ResponseContentType } from '@angular/http'
import 'rxjs/add/operator/map'
import {HttpHeaders, HttpClient} from '@angular/common/http'
import 'rxjs/add/operator/toPromise';
import { environment } from '../../../environments/environment';

@Injectable()
export class adminservice{

    constructor (public _http:Http, public http:HttpClient){}

    private url2="/api/users/savepreferences";
    private url3="/api/users/fetchpreferences";

    postcustomertablepreferences(modelcheckbox){
        return this._http.post(this.url2, modelcheckbox, {withCredentials:true}).map(res=>res.json());
    }

    getpreferences(data){
        return this._http.post(this.url3, data, {withCredentials:true}).map(res=>res.json());
    }
}

我在将数组推入modelupdatecurrency并尝试发布时遇到了问题。

Answer 1

curl -X POST \
   https://login.windows.net/<tenant>/oauth2/token \
   -H 'Accept: application/json' \
   -H 'Content-Type: application/x-www-form-urlencoded' \
   -d 'grant_type=password&scope=openid&resource=<resourceUri>&client_id=<yourClientId>&client_secret=<clientSecret>&username=<username>&password=<password>'

this.datasas = this.modelupdatecurrencycheckbox.push()方法返回一个新的数组长度。

请参阅此link。

push()-代替此，使用：

console.log("sda" + JSON.stringify(datasas))

在复选框数组中推送数组，但是我在Angular 2中遇到了一些问题
