Angular2中路由器的延迟 [英] Delay for router in Angular2

问题描述

我有这段代码，它具有2个功能: say()将播放音乐(已实现并且可以运行) 并且router转到下一页(也可以)

I have this code, which have 2 functions: say() will play the music (is implemented and it works) and router leads to next page (it works also)

go_next() {
     this.say(); // audio
     this.router.navigate( ['app'], { queryParams: { 'part': this.part+1 } } ); //go to next page 
}

但是我想做的是播放音乐(需要5秒钟)，然后转到下一页...我该如何实现呢?.我想，我必须实现某种delay，但是router.navigate我找不到这样的参数.

But what I would like to do is to play music (it takes 5 sec) and then to go to the next page...how could I implement this?..I guess, I have to implement some kind of delay, but I can't find such parameter by router.navigate.

推荐答案

setTimeout(函数，毫秒)等待后执行一个函数 指定的毫秒数.

setTimeout(function, milliseconds) Executes a function, after waiting a specified number of milliseconds.

go_next(){
    setTimeout(() => {
        this.router.navigate(['app'], {queryParams: {'part': this.part + 1}})
      }
      , 5000);
}
