Angular 2将表单序列化为JSON格式 [英] Angular 2 Form Serialization Into JSON Format

问题描述

创建我的Angular 2表单并将提交的数据转换为JSON格式以用于将其提交给我的API时遇到了一些麻烦。我正在寻找一些与此示例非常相似的东西：
$。fn.serializeObject = function（）
http://jsfiddle.net/sxGtM/3/
这个例子的唯一问题是代码是用JQuery编写的，而我试图使用严格的角度2.
任何帮助将不胜感激，我仍然是非常新的角。

I am having a little bit of trouble creating my Angular 2 form and converting the submitted data into JSON format for the use of submitting it to my API. I am looking for something that works very similarly to this example: $.fn.serializeObject = function() http://jsfiddle.net/sxGtM/3/
The only problem with this example is that the code is written in JQuery, whereas I'm trying to use strictly angular 2. Any help would be greatly appreciated, I am still very new to angular.

推荐答案

如果您使用 FormGroup ，您可以使用 getRawValue（）函数返回然后可以使用 JSON.stringify（）。

If you're using a FormGroup, you can use the getRawValue() function to return an object that can then be serialized using JSON.stringify().

import { Component, OnInit } from '@angular/core';
import { FormGroup, FormBuilder } from '@angular/forms'
import { Http } from '@angular/http';

@Component({
    selector: 'my-component',
    templateUrl: 'my-component.component.html'
})
export class MyComponent implements OnInit {

    form: FormGroup;

    constructor(private fbuilder: FormBuilder,
                private http: Http) { }

    ngOnInit(){
        this.form = this.fbuilder.group({
            name: '',
            description: ''
        });
    }

    sendToAPI(){
        let formObj = this.form.getRawValue(); // {name: '', description: ''}

        let serializedForm = JSON.stringify(formObj);

        this.http.post("www.domain.com/api", serializedForm)
            .subscribe(
                data => console.log("success!", data),
                error => console.error("couldn't post because", error)
            );
    }
}
