Angular 2-单击div后更改视频src [英] Angular 2 - change videos src after clicking on div

问题描述

我对视频src有问题.在源代码中单击我的div(摄像机)后，我可以看到video src正确更改，但是正在播放视频.我该怎么办?

I have problem with video src. After clicking on my div (camera) in source code I can see that video src is changing properly, but videos arent being played. What should I do?

下面是我的组件-stream.component.ts(用于显示所选摄像机组件的视频)和camera.component.ts(用于查看带有摄像机名称的图标)

Below are my components - streaming.component.ts (responsible for displaying videos of chosen camera component) and camera.component.ts (for viewing icon with camera name)

streaming.component.ts

import {Component} from '@angular/core';
import {CameraComponent} from '../camera/camera.component';

@Component({
   moduleId: module.id,
   selector: 'streaming',
   template: `
            <camera cameraName="Kamera 1" (click)='cameraStream("sample.mp4")'></camera>
            <camera cameraName="Kamera 2" (click)='cameraStream("sample2.mp4")'></camera>
            <camera cameraName="Kamera 3" (click)='cameraStream("sample3.mp4")'></camera>
            <camera cameraName="Kamera 4" (click)='cameraStream("sample4.mp4")'></camera>
            <video width="800" controls>
                <source src = "{{cameraSrc}}" type="video/mp4">
                Your browser does not support HTML5 video.
            </video>
            <p>{{cameraSrc}}</p>
            `,
directives: [CameraComponent]
})
export class StreamingComponent {

 cameraSrc:string;
 constructor() { }

 cameraStream(chosenCamera :string){
    this.cameraSrc=chosenCamera;
  }
 }

因为我放了

<source src = "{{cameraSrc}}" type="video/mp4">

一切都很好.

camera.component.ts

import { Component ,Input } from '@angular/core';

@Component({
    moduleId: module.id,
    selector: 'camera',
    templateUrl: 'camera.component.html'
})
export class CameraComponent {
     @Input() cameraName:string = "";

     constructor() { }

 }

例如，这是我在单击camera2后得到的内容

推荐答案

不知道为什么，但是那样:

Don't know why, but that way:

<video width="800" [src] = "cameraSrc" controls>
    Your browser does not support HTML5 video.
</video>

正在工作.
