getset formBuilder 控制参数
有两种方法可以设置 formBuilder 控件参数。
- 初始化时:
exampleForm : FormGroup;
constructor(fb: FormBuilder){
this.exampleForm = fb.group({
name : new FormControl({value: 'default name'}, Validators.compose([Validators.required, Validators.maxLength(15)]))
});
}
2.初始化后:
this.exampleForm.controls['name'].setValue('default name');
获取 formBuilder 控件值:
let name = this.exampleForm.controls['name'].value();
