在Angular2中执行router.navigate之后的代码

Question

我想知道在使用角度路由器导航到不同的"视图"之后是否有办法执行某些操作.

this.router.navigate(["/search", "1", ""]);
// Everything after navigate does not not get executed.
this.sideFiltersService.discoverFilter(category);

Answer 1

this.router.navigate返回一个promise,所以你可以简单地使用:

this.router.navigate(["/search", "1", ""]).then(()=>{
  // do whatever you need after navigation succeeds
});
