我已经试着从这里效仿其他答案，但我没有成功!
我创建了一个响应式表单(即，动态)，我想在任何给定的时间禁用一些字段。我的表单代码:
this.form = this._fb.group({
name: ['', Validators.required],
options: this._fb.array([])
});
const control = <FormArray>this.form.controls['options'];
control.push(this._fb.group({
value: ['']
}));
我的html:
<div class='row' formArrayName="options">
<div *ngFor="let opt of form.controls.options.controls; let i=index">
<div [formGroupName]="i">
<select formArrayName="value">
<option></option>
<option>{{ opt.controls.value }}</option>
</select>
</div>
</div>
</div>
为了方便起见，我简化了代码。我想禁用类型选择字段。我试着这样做:
form = new FormGroup({
first: new FormControl({value: '', disabled: true}, Validators.required),
});
不工作!有人有什么建议吗?
我试图从localstorage获取值，我想要禁用电子邮件和密码字段。这招对我很管用:
email: new FormControl({value: localStorage.getItem("email"), disabled:true},[
Validators.required,
Validators.minLength(3),
]),
password: new FormControl({value: localStorage.getItem("password"), disabled:true},[
Validators.required,
Validators.minLength(3),
])
角度 14+
field = new FormControl<any>()
readonly formGroup = new FormGroup<any>({
field2: new FormControl<any>(),
});
选项1
ngOnInit() {
# ...
this.field.setDisable();
this.field.setEnable();
this.formGroup.controls.field2.setEnable();
this.formGroup.controls.field2.setDisabled();
# ...
}
选项2
private setFieldEnabled() {
this.field.setEnable()
}
private setFieldDisabled() {
this.field.setDisable()
}
private setField2Enabled() {
this.formGroup.controls.breakdown.setEnable();
}
private setField2Disabled() {
this.formGroup.controls.breakdown.setDisable();
}
setEnableOrDisableFields(truth: boolean): void {
if (truth) {
this.setFieldEnabled()
this.setField2Enabled();
return
}
this.setFieldDisabled()
this.setField2Disabled();
}
