我目前正在使用Swiper(https://www.npmjs.com/package/angular2-useful-swiper)来创建图片库。
是否可以通过迭代对象数组并使用ngClass来动态更改div的类?我不确定是否支持插值。
我不断收到的错误说明"标识符'样式'没有定义。 '阵列'不包含这样的会员。'但是为什么ngStyle,h4和p能够抓住元素并迭代它,如果是这样的呢?
slider.component.html
<div class="swiper-container">
<swiper class="swiper" [config]="config">
<div class="swiper-wrapper">
<div class="swiper-slide" *ngFor="let image of images">
<div class="swiper-slide--container">
<div class="symptom-slide-img"
[ngClass]="images.style" [ngStyle]="{'background-image': 'url(' + image.src + ')'}"></div>
<div class="caption">
<h4>{{ image.title }}</h4>
<p>{{ image.caption}}</p>
</div>
</div>
</div>
</div>
<div class="swiper-button-next"></div>
<div class="swiper-button-prev"></div>
</swiper>
</div>
slider.component.ts
import { Component, OnInit } from '@angular/core';
import { NgClass } from '@angular/common';
@Component({

export class SymptomsSliderComponent implements OnInit {
images = [ {
'src': './path/image.png',
'title': 'Title',
'style': 'hvr-pulse-grow',

'Caption'

{

{

'title': 'Title',
'style': 'hvr-wobble-vertical',
'caption':
'Caption'

];
constructor() { }
ngOnInit() {
}
}

[ngClass]="images.
至[ngClass]="image.
