指令[(ngModel)] =在rc5中不再起作用 [英] The directive [(ngModel)]= not working anymore in rc5

问题描述

ngModel抛出异常，在rc4中可以正常工作

ngModel is throwing exceptions, this worked fine in rc4

<input [(ngModel)]="par.name" placeholder="name" />

这些是例外:

zone.js@0.6.12?main = browser:260未捕获的异常:错误 ./CommunityListComponent类CommunityListComponent-内联 模板:10:27原始例外:没有用于表单控件的值访问器 带有未指定名称的原始堆栈:错误:无值访问器 用于具有未指定名称的表单控件

zone.js@0.6.12?main=browser:260 Uncaught EXCEPTION: Error in ./CommunityListComponent class CommunityListComponent - inline template:10:27 ORIGINAL EXCEPTION: No value accessor for form control with unspecified name ORIGINAL STACKTRACE: Error: No value accessor for form control with unspecified name

推荐答案

也可以通过将FormsModule导入您的引导程序模块来解决，然后它将对所有组件可用.

can also solve by importing FormsModule into your bootstrap module, then it will be available to all components.

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule } from '@angular/forms';

import { AppComponent } from 'app/components/app';

@NgModule({
    imports: [BrowserModule, FormsModule],
    declarations: [AppComponent],
    bootstrap: [AppComponent]
})

export class AppModule { }
