当Angular加载应用程序时,我试图在“App Loading”屏幕中设置fadeout效果的动画。但是,我找不到办法。这是代码:
<div class="container">
<my-app>
<div class="loadingComp">
<div class="sk-folding-cube">
<div class="sk-cube1 sk-cube"></div>
<div class="sk-cube2 sk-cube"></div>
<div class="sk-cube4 sk-cube"></div>
<div class="sk-cube3 sk-cube"></div>
</div>
<span>App loading, please wait.</span>
</div>
</my-app>
尝试下面的CSS,但徒劳无功:
my-app:empty + .loadingComp {
opacity: 1;
}
my-app:not(:empty) + .loadingComp {
opacity: 0;
animation: fadeOut 0.5s ease-in-out;
}
@keyframes fadeOut {
0% {
opacity: 1;
}
100% {
opacity: 0;
}
}
甚至尝试使用Angular Animations,但没有工作。有什么建议??

我不确定您是否要fadeOut
'App Loading ...'消息或加载的第一个组件。但我会介绍这两种情况。
要在加载根组件之前为“App Loading”消息设置动画,需要添加一个可以运行动画的脚本。我正在使用jQuery fadeTo()
功能(doc)。
的index.html:
<!DOCTYPE html>
<html>
<head>
<base href="." />
<title>angular playground</title>
<link rel="stylesheet" href="style.css" />
<script src="https://unpkg.com/core-js@2.4.1/client/shim.min.js"></script>
<script src="https://unpkg.com/zone.js/dist/zone.js"></script>
<script src="https://unpkg.com/zone.js/dist/long-stack-trace-zone.js"></script>
<script src="https://unpkg.com/reflect-metadata@0.1.3/Reflect.js"></script>
<script src="https://unpkg.com/systemjs@0.19.31/dist/system.js"></script>
<script src="config.js"></script>
<script>
System.import('app')
.catch(console.error.bind(console));
</script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
</head>
<body>
<style>
#animate {
width: 100%;
height: 250px;
position: absolute;
background-color: red;
}
</style>
<my-app>
<div id="animate"><h1>App loading, please wait.</h1></div>
</my-app>
<script>
$( "#animate" ).fadeTo( 750 , 0.1, function() {
// Animation complete.
});
</script>
</body>
</html>
要向组件添加动画,我添加了animations
元数据。
app.ts:
import {Component, NgModule, Input, VERSION} from '@angular/core'
import {BrowserModule} from '@angular/platform-browser'
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import {
trigger,
state,
style,
animate,
transition
} from '@angular/animations';
@Component({
selector: 'my-app',
template: `
<div [@flyInOut]="'out'">
<h2>Hello {{name}}</h2>
</div>
`,
animations: [
trigger('flyInOut', [
state('out', style({opacity: 0, transform: 'translateX(0)'})),
transition('void => *', [
style({
opacity: 1,
//transform: 'translateX(-100%)'
}),
animate('1s ease-in')
]),
transition('* => void', [
animate('0.2s 10 ease-out', style({
opacity: 0,
transform: 'translateX(100%)'
}))
])
])
]
})
export class App {
name:string;
constructor() {
this.name = `Angular! v${VERSION.full}`
}
}
@NgModule({
imports: [ BrowserModule, BrowserAnimationsModule ],
declarations: [ App ],
bootstrap: [ App ]
})
export class AppModule {}
以下是Plunker demo以供参考。希望这有帮助!

感谢Nehal的时间。我用jQuery解决了它,但是一个不同的方法。我分配了一个&#39; id&#39;到我的应用程序&#39;选择器并在jQuery中使用它。
我用过这个:
$("body").on('DOMSubtreeModified', "#myApp", function () {
$('.loadingComp').fadeOut(function () {
$(this).remove();
});
});
