当我在我的 angular 应用程序中进行验证时，我遇到了这个错误：
src/app/register/register.component.ts:45:39 - error TS7053: Element implicitly has an 'any' type because expression of type 'string' can't be used to index type 'AbstractControl[] | { [key: string]: AbstractControl; }'.
No index signature with a parameter of type 'string' was found on type 'AbstractControl[] | { [key: string]: AbstractControl; }'.

<button type="button" class="deleteproductModal btn btn-xs btn-default btn-flat"
data-toggle="modal"
data-product_token="{{ csrf_token() }}"
data-product_name="{{ $slide->title_slider }}"
data-product_destroy_route="{{ route('slider.destroy', $slide->id) }}">
<i class="fa fa-trash"></i>
</button>
{!! Form::close() !!}
单击按钮时，将执行以下 javascript 调用控制器中的 destroy 方法以从数据库中删除产品：
$('button.deleteproductModal').click(function()
{
var productRoute = $(this).attr("data-product_destroy_route");
var productName = $(this).attr("data-product_name");
var productToken = $(this).attr("data-product_token");
deleteproduct(productRoute, productToken, productName);
});
function deleteproduct(productRoute, productToken, productName)
{
