Question

我在自己的组件中使用Material UI Card通过iframe显示youtube视频。一切都很好，但是我无法使视频全屏显示，fullscreen is unavailable

import React from "react";
import PropTypes from "prop-types";
import { withStyles } from "@material-ui/core/styles";
import Card from "@material-ui/core/Card";
import CardActionArea from "@material-ui/core/CardActionArea";
import CardActions from "@material-ui/core/CardActions";
import CardContent from "@material-ui/core/CardContent";
import CardMedia from "@material-ui/core/CardMedia";
import Button from "@material-ui/core/Button";
import Typography from "@material-ui/core/Typography";

const styles = {
 card: {
    backgroundColor: "pink",
    width: 680,
    height: 500,
    textAlign: "center",
  },
  media: {
    width: 480, height: 360,
    marginLeft: "auto",
    marginRight: "auto"
  }
};

const ImgMediaCard = (props) => {
  const { classes } = props;
  return (
    <Card className={classes.card}>
      <CardActionArea>
        <CardMedia
          component="iframe"
          alt="Contemplative Reptile"
          className={classes.media}
          height="140"
          image="https://www.youtube.com/embed/Ke90Tje7VS0"
          title="Contemplative Reptile"
        />
        <CardContent>
          <Typography gutterBottom variant="h5" component="h2">
            Lizard
          </Typography>
          <Typography component="p">
            Lizards are a widespread group of squamate reptiles, with over 6,000
            species, ranging across all continents except Antarctica
          </Typography>
        </CardContent>
      </CardActionArea>
    </Card>
  );
}

export default withStyles(styles)(ImgMediaCard);

Answer 1

材料UI在CardMedia组件中不提供全屏功能。但是您可以使用替代方法来实现。请参见下面的代码。

import React from "react";

import PropTypes from "prop-types"; 
import { withStyles } from "@material-ui/core/styles"; 
import Card from "@material-ui/core/Card"; import CardActionArea from
"@material-ui/core/CardActionArea"; import CardActions from
"@material-ui/core/CardActions"; import CardContent from
"@material-ui/core/CardContent"; import CardMedia from
"@material-ui/core/CardMedia"; import Button from
"@material-ui/core/Button"; import Typography from
"@material-ui/core/Typography";

const styles = {   card: {
    // textAlign: "center",
    backgroundColor: "pink",
    width: 680,
    height: 500,
    textAlign: "center"   },   media: {
    // ⚠️ object-fit is not supported by IE11.
    //objectFit: "cover",
    width: 480,
    height: 360,

    marginLeft: "auto",
    marginRight: "auto"   } }; class ImgMediaCard extends React.Component{



  componentDidMount() {

    try {
      document.getElementById("iframeM").setAttribute("allowfullscreen",
"true")
      document.getElementById("iframeM").setAttribute("src", "https://www.youtube.com/embed/Ke90Tje7VS0")
    } catch (error) {

    }

  } render() {   const { classes } = this.props;
     return (
    <Card className={classes.card}>
    {}
      <CardActionArea>
      <CardMedia
          id ="iframeM"
          component="iframe"
          alt="Contemplative Reptile"
          className={classes.media}
          height="140"
          title="Contemplative Reptile"
        />
        <CardContent>
          <Typography gutterBottom variant="h5" component="h2">
            Lizard
          </Typography>
          <Typography component="p">
            Lizards are a widespread group of squamate reptiles, with over 6,000
            species, ranging across all continents except Antarctica
          </Typography>
        </CardContent>
      </CardActionArea>
    </Card>   ); } }

ImgMediaCard.propTypes = {   classes: PropTypes.object.isRequired };

export default withStyles(styles)(ImgMediaCard);

请参见上面的代码，您可以为CardMedia组件指定ID，因为CardMedia组件不会在iframe代码中添加allowfullscreen属性。因此，您需要手动执行操作，这对定义src也很重要，即手动嵌入视频的源网址，就像我所做的那样：

document.getElementById("iframeM").setAttribute("allowfullscreen",
"true")
document.getElementById("iframeM").setAttribute("src", 
"https://www.youtube.com/embed/Ke90Tje7VS0")

由于iframeM是CardMedia组件的ID，并且我要手动添加src，allowfullscreen属性。

还要在本地计算机环境上运行此代码。我正在附上经过测试的代码的视频。 Video of tested code

Answer 2

这似乎在较新的 material-ui 版本中发生了变化。我能够添加属性

<块引用>

allowfullscreen="allowfullscreen"

它适用于 Chrome、Firefox 和 Edge。

<CardMedia
    component="iframe"
    title="Your Title"
    src="https://www.youtube.com/embed/[your_video"
    allowfullscreen="allowfullscreen"
/>

无法将iframe全屏显示
