如何在 ngZone 之外 运行 异步函数?
How to run async function outside ngZone?
我尝试在当前区域外运行脚本:
async ngAfterViewInit(): Promise<void> {
this.ngZone.runOutsideAngular(() => {
await this.run();
});
}
async run() { // TODO }
我收到这个错误:
'await' expressions are only allowed within async functions and at the top levels of modules.ts
ngAfterViewInit 函数是异步的,但您使用了 this.ngZone.runOutsideAngular 和非异步回调函数。
您的代码需要如下所示...
ngAfterViewInit(): void {
this.ngZone.runOutsideAngular(async () => {
await this.run();
});
}
async run() { // TODO }
