小编Mis*_*sar的帖子

我有这个产生的字符串：

string str = [{"id":1,"name":"Angular"},{"id":2,"name":"SpringBoot"}]

我想将其转换为Objects数组以使其具有：

listexps: Expertise[];
listexps = [{"id":1,"name":"Angular"},{"id":2,"name":"SpringBoot"}];

而专门知识课程是

export class Expertise
{
    id: number;
    name: string;
}

我尝试过：

let array = str .replace('[{','').replace('}]','').split("},{").map(String);

但这并不能解决我的问题，我得到了：

"id":1,"name":"Angular","id":2,"name":"SpringBoot"

代替

[{"id":1,"name":"Angular"},{"id":2,"name":"SpringBoot"}];

您对解决这个问题有任何想法吗？非常感谢。

我有此映射用户* ------------------------ 1职业。我想修改一个用户。所以我从中选择一个list-users.component.html，我将被重定向到modify-user.component.html。

以下是必需的文件：

Modify-user.component.html

<form [formGroup]="editForm" (ngSubmit)="onSubmit()">
        <div class="form-group">
            <label for="name">Name</label>
            <input type="text" formControlName="name" placeholder="Name" name="name" class="form-control" id="name">
        </div>
        <div *ngFor='let pro of professions; let i = index'>
            <label>
                <input type="radio"
                       id="pro.id" 
                       checked="pro.selected" 
                       name="pro"
                       [(ngModel)]="this.editForm.pro"
                       (change)='radioChecked(pro.id, i)'
                       [value]="pro.libelle">
                <span></span>
                <span class="check"></span>
                <span class="box"></span>
                {{pro.libelle}}
            </label>
        </div>
        <p>==> {{selectedProfessionRadio}}</p>
        <button class="btn btn-success">Update</button>
    </form>

Modify-user.component.ts

export class ModifyUserComponent implements OnInit
{

    private selectedProfessionRadio;
    professionLib: string;
    editForm: FormGroup;
    usrId: String;

    professions: Profession[] =
    [
