构建一个接受值 (attribute.readonly
) 的组件,并且只显示前 40 个字符,除非触发了 <Chevron onClick
这意味着我想显示 fullDescription
而不是shortHeading
- 理想情况下,这将类似于当前仅将 Accordion
的高度加倍的方式,以允许其余内容适合。我知道我仍然有点偏离,但我真的很感激我接下来的步骤/想法来改进我已经拥有的东西!
// @flow
import styled from "styled-components";
import chevron from "../Assets/chevron-icon.svg";
type Props = { attribute: AttributeType, className?: string };
const Accordion = styled.div`
background-color: #e5e9eb;
height: 56px;
width: 612px;
border-radius: 2px;
border: 1px solid #27282a;
margin-bottom: 48px;
display: flex;
align-items: center;
span {
padding-left: 24px;
}
`;
const Chevron = styled.img`
height: 40px;
width: 40px;
float: right;
margin-right: 12px;
`;
const ExpandableString = ({ attribute, className }: Props) => {
const fullDescription = attribute.readonlyvalue;
const shortHeading = fullDescription.substring(0, 40) + '...';
const isExpanded = false;
function toggleContent() {
isExpanded = true;
}
return (
<Accordion className={className}>
<span>{shortHeading}</span>
<Chevron onClick={toggleContent} src={chevron} alt="Expand or collapse content" />
</Accordion>
);
};
export default ExpandableString;

将您的数据放入状态并切换它

然后,根据 const ExpandableString = ({ attribute, className }: Props) => {
const [isExpanded, setIsExpanded] = React.useState(false);
function toggleContent() {
setIsExpanded(prev => !prev);
}
return (
<Accordion className={className}>
<span>{shortHeading}</span>
<Chevron onClick={toggleContent} src={chevron} alt="Expand or collapse content" />
</Accordion>
);
};
状态,您可以有条件地渲染您的 React 组件。
