在带有反应形式的角度v4中使用禁用状态时，无法将复选框值设置为false

Question

I will build the form with a form builder and include the following:

myCheckbox: [{ value: true, disabled: false }, ''],

Then I will try to patch the value, but this will only work if I am going from false to true, not from true to false:

 this.myForm.get('selectedItem').patchValue({
                selectedItem1: [{ value: false, disabled: false }, '']
            });

Am I missing something? Everything worked fine, until I used the recommended way for handling disabled state.

The checkbox looks like this in the html:

<label class="checkbox-inline"><input type="checkbox" name="selectedItem1" formControlName="selectedItem1">Week 1</label>

Answer 1

It should just be:

this.myForm.get('selectedItem').patchValue({
    myCheckbox: false
});
