Отображение каскадных карт mdbootstrap
Здравствуйте все,
Я строю веб-сайт, используя ответ JS. Теперь я хочу отобразить три каскадных карты mdbootstrap, используя ответ js.
Вот скриншот
Возлюбленный код: (обратите внимание, что на этой странице есть навигационная панель, видеокарусель, каскадные карты и нижний колонтитул).
import React, { Component } from 'react';
import { Container, CarouselIndicator, Row, Col, CardTitle, CardText, CardBody, CardImage, Button, Card, CarouselIndicators, Carousel, CarouselControl, CarouselInner, CarouselItem } from 'mdbreact';
export default class Home extends Component {
constructor(props) {
super(props);
this.next = this.next.bind(this);
this.prev = this.prev.bind(this);
this.state = {
activeItem: 1,
maxLength: 3
};
}
next() {
const nextItem = this.state.activeItem + 1;
if(nextItem > this.state.maxLength) {
this.setState({ activeItem: 1 });
} else {
this.setState({ activeItem: nextItem });
}
}
prev() {
const prevItem = this.state.activeItem - 1;
if(prevItem < 1) {
this.setState({ activeItem: this.state.maxLength });
} else {
this.setState({ activeItem: prevItem });
}
}
goToIndex(item) {
if (this.state.activeItem !== item) {
this.setState({
activeItem: item
});
}
}
render(){
const { activeItem } = this.state;
return(

В моем случае, карусель с несколькими предметами - одна из особенностей про версии. Но я попытался решить этот случай с бесплатной версией и обнаружил, что компоненты Row и Col не работают для этого случая.
Итак, я удалил его и обернул карты компонентов внутри CarouselItem с
<div style={{flexDirection: "row"}}> ... </div>
Я надеюсь, что это может быть полезно.
