Question

我有一个ng-select和角度反应形式。我配置了它：

this.form1 = this.fb.group({
  test: [null, null]
});


this.items = [
    {
     code: 'A',
     description: 'TEST A'
    },
    {
     code: 'B',
     description: 'TEST B'
    }

 ]

   <ng-select [items]="items" 
       (change)="onSelected($event)"
       bindLabel="description"
       class="selectbox"> 
    </ng-select>  


onSelected(event){
   this.form1.controls['test'].setValue(event);

   // this.form1.controls['test'].value =  {code: 'A',description: 'TEST A'}
}

现在ng-select起作用了。但是如果我在init上设置值，我会尝试

  this.form1.patchValue({
     test: {code: A}
  })

但不要担心。我想使用this.form1.patchValue（{ 测试：{code：A} }）

有什么想法吗？谢谢马可

将formControlname绑定到ng-select，然后在初始设置

this.form1.patchValue({ test: {code: A} })，或者如果您的ng-select设置为[multiple] =“ true”，那么

this.form1.patchValue({ test: [{code: A}] })

ng-select请勿在反应式表单上设置值
