我们可以使用复选框的 [checked] 属性的方法将其设置为 true/false

Question

I want to set the [checked] property of the checkbox on a method call, but when I do that, the method is called but it doesn't change the status of the checkbox

HTML

<div*ngFor="let vest_style of VEST_STYLE">
    <input type="checkbox" value="{{vest_style._id}}" (change)="onCheckboxChange($event,i)" 
    [checked]="isCheckedFromOrder(vest_style._id)">&nbsp;{{vest_style.name}}
</div>

TS

isCheckedFromOrder(id) {
    this.styles.value.forEach(style => {
      console.log(style === id)
      return style === id
    })
  }

Answer 1

i know what the issue is. Instead of your code, use the following.

let checked = false;
this.style.value.forEach(style => {
if (style == id) checked = true;
});
return checked;
