Question

当我在下面的代码中输入 Monday From 和 Monday To 的时间时，我在控制台中收到此错误我有一个开关，我想复制我为星期一 From/To 输入的时间一周中的。为什么我会收到这个错误，我该怎么做才能修复它。

这是拨动开关按钮的代码

 <b-form-checkbox switch v-model="providerScheduleDays.isCopytoMF" 
  @change="toggleCopyMF($event.target.checked)"> Copy times to Mon-Fri</b-form-checkbox>

周一到/从和周二到/从的输入

打字稿文件中的函数

copyDate = false;
toggleCopyMF(isActive: boolean) {this.copyDate = isActive 
if(this.copyDate) {this.copyValuesMF(this.providerScheduleDays.mondayOpenHour); 
  this.copyValuesMF(this.providerScheduleDays.mondayCloseHour);
 } 
}   
copyValuesMF(value: string | undefined) {if(this.copyDate) {this.providerScheduleDays.tuesdayOpenHour 
 = value;
this.providerScheduleDays.tuesdayCloseHour = value }     
}

不建议在 HTML 中展开事件对象

@change="toggleCopyMF($event.target.checked)

因为它使调试变得更加困难。我建议将您的整个事件对象交给 toggleCopyMF() 方法，并查看事件的实际结构。也许它没有 target 成员，这就是它被视为未定义的原因。

HTML

@change="toggleCopyMF($event)

TS

toggleCopyMF(event: any) {
    console.log(event);

    // the rest of your code
}

类型错误：无法读取未定义的属性“已检查”
