全部 我正在製作一個使用Angular 2的小型Web應用程序,並且我想在其中使用JQuery。 我得到在Chrome中的錯誤,我不知道爲什麼 以下是錯誤:
core.umd.js:3004 EXCEPTION: Uncaught (in promise): Error: Error in `enter code here`http://localhost:3000/app/dashboard.component.js class DashboardComponent_Host - inline template:0:0 caused by: $ is not defined

at eval (http://localhost:3000/node_modules/@angular/router/bundles/router.umd.js:2902:23)
這裏是我的代碼:
import { Component, ElementRef, OnInit } from '@angular/core';
declare var $:JQueryStatic;
@Component({
moduleId: module.id,
selector: 'my-dashboard',
templateUrl: 'dashboard.component.html',
styleUrls: ['dashboard.component.css'],
})
export class DashboardComponent implements OnInit{
constructor(private elRef: ElementRef){}
ngOnInit():any{
$(this.elRef.nativeElement).find('button').on('click', function() {
alert('It works!');
});
}
}
我用這個答案來安裝jQuery和做一切都如解釋,但不起作用。 link 任何想法爲什麼? 感謝
FIX 我固定它通過改變declare var $:JQueryStatic;
到declare var $:any;
並列入<script src="https://code.jquery.com/jquery-2.2.0.min.js"></script>
到index.html
您是否嘗試過類似的 'jQuery的''進口$;'? –
@DanielD我剛剛做了,它說'模塊「jquery」沒有默認導出。「#: –
