所以我把<script>
放在一个组件中, StartComponent 。
StartComponent 位于 Root 或AppComponent内的<router-outlet>
。
我已经在单个index.html
文件(非角色或非基于组件)中对此进行了测试。但我不知道为什么它在Angular 4(基于组件)
start.component.html ( StartComponent )
var i = 0;
var images = [];
var time = 1000;
// Image list
images[0] = 'assets/pictures/kapal02.jpg';
images[1] = 'assets/pictures/kapal01.jpg';
images[2] = 'assest/pictures/truck.jpg';
// Function
function changeImage() {
document.getElementById('slideshow').src = images[i];
if(i < images.length - 1) {
i++;
}
else {
i = 0;
}
setTimeout("changeImage()", time);
}
window.onload = changeImage;
<img id="slideshow" src="assets/pictures/kapal02.jpg">

我已经创建了这个简单的plunker如何在angular2中执行此操作。请看一下home.component文件。这将让您了解如何以angular2方式解决这个问题。
家庭组件代码如下
export class HomeComponent implements OnInit {
urlVariable:string;
images:Array<any>
ngOnInit() {
var i = 0;
this.images = [];
var time = 1000;
// Image list
this.images[0] = 'http://i64.tinypic.com/2czam2x.jpg';
this.images[1] = 'http://i63.tinypic.com/2czanp2.jpg';
this.images[2] = 'http://i63.tinypic.com/2czaq8k.jpg';
this.urlVariable = this.images[0];
}
setImage(index:number){
this.urlVariable = this.images[index];
}
}
