Question

我在页面上有两个表单，有一个结算表单和一个发货表单。用户可以通过切换切换按钮来决定开票表单是否与装运表单相同。我想强制用户在提交按钮之前输入所有细节。但是，当用户确定帐单地址与送货地址相同时，他只需输入送货详细信息。

我已将required添加到所有字段，但我可以在不输入详细信息的情况下提交表单。

Answer 1

您可以执行的一个选项是禁用提交按钮

<button type="submit" [disabled]="!f.valid">Submit</button>

或仅在表格有效时才起作用

模板

<form #f="ngForm" (ngSubmit)="onSubmit(f.valid)">
  ...
    //code with submit button
  ...
</form>

成分</ P>

onSubmit(valid : boolean)
{
 if(valid == true)
   {
   //do action
   }
}
