Joh*_*hur 5 ngx-translate angular
我在 Angular7 中遇到了 NGX-Translate 的问题。
我正在尝试翻译带有参数的短语。如果参数是硬编码的,它可以工作,但如果参数是一个变量,它就不起作用。
app.component.ts
import { Component, OnInit } from '@angular/core';
import { TranslateService } from '@ngx-translate/core';
@Component({
selector: 'my-app',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
hardcoded: string;
fromVariable: string;
days: '30';
constructor(private translate: TranslateService) { }
ngOnInit() {
this.translate.setDefaultLang('en');
this.translate.use('en');
// Value Hardcoded - THIS WORKS
this.translate.get('UPCOMING_RENEWALS', { output: '30' }).subscribe((s: string) => {
this.hardcoded = s;
});
// value from variable - THIS DOESN'T
this.translate.get('UPCOMING_RENEWALS', { output: this.days }).subscribe((s: string) => {
this.fromVariable = s;
});
}
}

<h1>
{{ 'UPCOMING_RENEWALS' | translate :{output:'30'} }}</h1>
outputs: Upcoming Renewals (30 days)
<h1>{{hardcoded}}</h1>
outputs: Upcoming Renewals (30 days)
<h1>{{fromVariable}}</h1>
outputs: Upcoming Renewals ({{output}} days)

这是https://stackblitz.com/edit/angular-failing-translate-variable上的示例
这是因为days: '30'. 你没有days正确初始化,你只是将它的类型设置为'30'这意味着你不能设置days除了'30'.
我认为这是一个错字。将其更改为days = '30'
