我有这些html按钮：

<form ngNativeValidate (ngSubmit)="onSubmit()" #add_form="ngForm">
     <button class="btn btn-primary " type="submit[disabled]="!add_form.valid">ADD</button>
     <button class="btn btn-default" (click)="back()">Back</button>

对于后退按钮，将
type=“button”
添加到声明中，如下所示：


<form ngNativeValidate (ngSubmit)="onSubmit()" #add_form="ngForm">
     <button class="btn btn-primary " type="submit[disabled]="!add_form.valid">ADD</button>
     <button type="button" class="btn btn-default" (click)="back()">Back</button>
</form>
