Edd*_*die 1 carousel bootstrap-4 angular
我试图在我的Angular 2应用程序中使用Bootstrap 4轮播。具体来说，我正在尝试复制此处完成的全角效果。我到达必须将元素连接到轮播的最后一点：
$('.carousel').carousel({
interval: 6000,
pause: "false"
});尝试编译时，出现以下错误：
错误：类型“ JQuery”上不存在属性“轮播”
我知道有ng-bootstrap组件，但是我无法以这种方式使转盘完全变宽。
这是我的代码（Typescript，CSS，HTML）：
import { Component, OnInit } from '@angular/core';
import * as $ from 'jquery';
@Component({
selector: 'app-home-carousel',
templateUrl: './home-carousel.component.html',
styleUrls: ['./home-carousel.component.css']
})
export class HomeCarouselComponent implements OnInit {
constructor() { }
ngOnInit() {
}
setupCarousel(): void {
var $item = $('.carousel .item');
var $wHeight = $(window).height();
$item.eq(0).addClass('active');
$item.height('400px');
$item.addClass('full-screen');
$('.carousel img').each(function() {
var $src = $(this).attr('src');
var $color = $(this).attr('data-color');
$(this).parent().css({
'background-image' : 'url(' + $src + ')',
'background-color' : $color
});
$(this).remove();
});
$(window).on('resize', function (){
$wHeight = $(window).height();
$item.height($wHeight);
});
$('.carousel').carousel({ // <-- ERROR is on the .carousel
interval: 6000,
pause: "false"
});
}
}h3 {
display: inline-block;
padding: 10px;
}
.full-screen {
background-size: cover;
background-position: center;
background-repeat: no-repeat;
height: 300px;

第1步。确保您已在angular-cli.json的脚本部分中提到了jQuery和Bootstrap.js。
"scripts": [
"../node_modules/jquery/dist/jquery.min.js",
"../node_modules/bootstrap/dist/js/bootstrap.min.js"
]
第2步。在您的home-carousel.component.ts中import { Component, OnInit } from '@angular/core';添加declare var $:any;如下代码：
import { Component, OnInit } from '@angular/core';
declare var $:any;
第3步。虽然不是强制性的，但是我发现将jQuery和JS代码放入其中更安全ngOnInit()：
ngOnInit() {
$('.carousel').carousel({
interval: 2000
});
}
我希望这行得通。
