MUI - 如何在悬停时为卡片深度设置动画？

Question

当鼠标悬停在上面时，我想为整个 Card 的深度设置动画。我尝试了这个（所以我是 React 的新手）但我不知道该怎么做：

 <Card
  linkButton={true}
  href="/servicios/"
  onClick={Link.handleClick} zDepth={3}
  onMouseEnter={this.setState({zDepth={1}})}>
</Card>

提前致谢。

constructor(props) {
  super(props);
  this.state = { shadow: 1 }
}

onMouseOver = () => this.setState({ shadow: 3 });
onMouseOut = () => this.setState({ shadow: 1 });

<Card
   onMouseOver={this.onMouseOver}
   onMouseOut={this.onMouseOut}
   zDepth={this.state.shadow}
>

更新#1

完整示例

// StyledCard.js

import React, { Component } from 'react';
import { Card } from 'material-ui/Card';

class StyledCard extends Component {
  state: {
    shadow: 1
  }

  onMouseOver = () => this.setState({ shadow: 3 });

  onMouseOut = () => this.setState({ shadow: 1 });

  render() {
    return (
      <Card
        onMouseOver={this.onMouseOver}
        onMouseOut={this.onMouseOut}
        zDepth={this.state.shadow}
      >
        {this.props.children}
      </Card>
    );
  }

export default StyledCard;

.

 // Container.js

import React from 'react';
import StyledCard from './StyledCard';

const Container = () => [
  <StyledCard>Card 1</StyledCard>,
  <StyledCard>Card 2</StyledCard>,
  <StyledCard>Card 3</StyledCard>,
];

export default Container;

更新#2

使用 HOC

 // withShadow.js

import React from 'react';

const withShadow = (Component, { init = 1, hovered = 3 }) => {
  return class extends React.Component {
    state: {
      shadow: init
    };

    onMouseOver = () => this.setState({ shadow: hovered });

    onMouseOut = () => this.setState({ shadow: init });

    render() {
      return (
        <Component
          onMouseOver={this.onMouseOver}
          onMouseOut={this.onMouseOut}
          zDepth={this.state.shadow}
          {...this.props}
        />
      );
    }
  };
};

export default withShadow;

.

 // Container.js

import React from 'react';
import { Card } from 'material-ui/Card';
import withShadow from './withShadow';

const CardWithShadow = withShadow(Card, { init: 2, hovered: 4 });

const Container = () => [
  <CardWithShadow>Card 1</CardWithShadow>,
  <CardWithShadow>Card 2</CardWithShadow>,
  <CardWithShadow>Card 3</CardWithShadow>,
];

export default Container;

Answer 2

5 年后仍然没有正确答案，当它悬停时你不必设置组件状态，只需使用伪类 :hover ：

 <Card
  sx={{
    ':hover': {
      boxShadow: 20, // theme.shadows[20]
    },
  }}
>

如果你想使用 styled() ：

 const options = {
  shouldForwardProp: (prop) => prop !== 'hoverShadow',
};
const StyledCard = styled(
  Card,
  options,
)(({ theme, hoverShadow = 1 }) => ({
  ':hover': {
    boxShadow: theme.shadows[hoverShadow],
  },
}));

 <StyledCard hoverShadow={10}>
  <Content />
</StyledCard>
