Angular2：禁用formbuilder的元素 [英] Angular2: Disable a formbuilder's element

问题描述

我正在尝试在声明后禁用我的formbuilder元素，因为我必须在加载视图后验证一些内容，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]
  });
}

我不知道怎么做，因为我想禁用<$完成本地验证后，c $ c> 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()
