无法在子对象

Question

我尝试将值设置为子组但却出错。下面是我的代码

let dataArr = new FormArray([]);
dataArr.push(new FormGroup({
'name': new FormControl(this.users[0].data[0].name),
'category': new FormControl(this.users[0].data[0].category)
}));
let formArr = <FormArray>this.myForm.controls.users;
formArr.push(this.fb.group({
name: this.users[0].name,
displayOrder: this.users[0].displayOrder,
sort: new FormGroup({ 
type:new FormControl(),
format: new FormControl()
}),
data: dataArr
}));

我尝试将值设置为具有类型和格式的对象。但无法设定。我的json对象是

[{"name":"manu","displayOrder":1,"sort":{
"type":"first","format":"normal"
},"data":[{"category":"electrical","name":"ele"}]},{"name":"divya","displayOrder":1,"data":[{"category":"tech","name":"ea_tcv"}]}]

如何设置值以排序对象？

Answer 1

我不是100％确定我正确理解你的问题，但是如果你需要为Sort对象设置值，你可以简单地将数据对象中的相应字段传递给FormControl构造函数：

{{1}}
