如何隐藏/删除在json模式表单Angular 2中生成的默认提交按钮

Question

Image of Issue ( update和cancel是正确的，提交按钮是不需要的)我正在尝试生成一个json模式表单，而不生成默认的提交按钮。该按钮在模式或html中未被引用，但它仍会生成。我得到的最接近的结果是在模式中使用"options"：false，这会导致一个错误，该错误会暂时删除按钮。有人知道怎么解决这个问题吗？

如果只想阻止提交按钮呈现，可以覆盖默认的提交按钮小部件。Angular2架构表单包含一个NoneCompnent，它可以提供无操作替换，替换任何您不想显示的内容。

your.component.html：

<json-schema-form
[schema]="yourJsonSchema"
[layout]="yourJsonFormLayout"
[(data)]="yourData"
[widgets]="yourWidgets"
...
>
</json-schema-form>

your.component.ts：

...

import { NoneComponent } from 'angular2-json-schema-form';

...

@Component({
  selector: 'app-your-component',
  templateUrl: './your.component.html',
  ...
})
export class YourComponent {

  yourWidgets = {
    submit: NoneComponent,  
  }

...
