角路由参数“状态”在类型“ NavigationExtras”中不存在

Question

我想通过这种方式将参数传递给另一个页面：

const navParams:NavigationExtras = {state: {functionalityId:'my id'}};
this.router.navigate(['processes'], navParams);

但是它给了我以下错误：

Type '{ state: { functionalityId: string; }; }' is not assignable to type 'NavigationExtras'.
  Object literal may only specify known properties, and 'state' does not exist in type 'NavigationExtras'.

我也试图直接在导航内传递参数：

this.router.navigate(['processes'], {functionalityId:'my id'});

但我有（几乎）相同的错误：

Argument of type '{ functionalityId: string; }' is not assignable to parameter of type 'NavigationExtras'.
  Object literal may only specify known properties, and 'functionalityId' does not exist in type 'NavigationExtras'

Answer 1

您的语法错误。您需要将方括号放在行尾，如下所示：this.router.navigate(['processes', { functionalityId: 'my id' }])
