如何在另一个内部的formbuilder上的对象上设置值-Typescript [英] How to set value on object on formbuilder inside another - Typescript

问题描述

我想访问现有的formBuilder并设置特定对象的值. 问题是这不是正常的formbuilder.它是另一个内部的formbuilder.

I want to access an existing formBuilder and set value of a specific object. The problem is that is not a normal formbuilder. It is a formbuilder inside another.

代码:

  formBuilder.group({
      nasty: formBuilder.group({
        myobject: ['', []],
      })});

如何在我的对象上设置值?

How can I set value on myobject?

推荐答案

这只是FormGroup中的FormGroup.

您可以patchValue整个表单对象.

this.form.patchValue({ nasty: { myobject: 'POPULATED' }})

或者您可以定位特定的目标.

Or you could target specific one.

this.form.get('nasty.something').patchValue('AND THIS TOO');
