Angular2:禁用表单构建器的元素 [英] Angular2: Disable a formbuilder's element

问题描述

我试图在声明之后禁用我的表单构建器的一个元素，因为一旦我的视图被加载，我必须验证一些东西，所以这是我的 formBuilder 声明.

I'm trying to disable an element of my formbuilder after the declaration because I have to validate something once my view is loaded, so this is my formBuilder declaration.

ionViewDidLoad() {
  this.purchaseDataForm = this.formBuilder.group({
    kms: ['', Validators.required],
    lts: ['', Validators.required],
    price: ['', Validators.required],
    total: ['', Validators.required]
  });
}

我不知道该怎么做，因为我想在完成本地验证后禁用 total 元素.我希望你能帮助我.

I have no idea how to do that because I want to disable the total element once finished my local validation. I hope you can help me.

谢谢！

推荐答案

this.purchaseDataForm.get('price').disable() // .enable()
