无法为包含 Material-UI 抽屉的页面创建页脚

Question

所以，有一个类似的问题，但这不是我需要的。我想在页面底部制作一个常规的全角页脚。为了理解主题，我使用了标准的“Permament drawer”，直接从 Material-UI Drawer. You can also try it out in CodeSandbox here 借来的。无论我尝试在那里添加什么，我都无法让我的页脚出现。有一次我设法让它出现了，但它还在抽屉下面，所以我只能看到抽屉右边的一部分。同样，我只需要一个基本的常规全角页脚。这是代码，以防您无法访问链接。

const drawerWidth = 240;

const useStyles = makeStyles((theme: Theme) =>
  createStyles({
    root: {
      display: 'flex',
    },
    appBar: {
      width: `calc(100% - ${drawerWidth}px)`,
      marginLeft: drawerWidth,
    },
    drawer: {
      width: drawerWidth,
      flexShrink: 0,
    },
    drawerPaper: {
      width: drawerWidth,
    },
    // necessary for content to be below app bar
    toolbar: theme.mixins.toolbar,
    content: {
      flexGrow: 1,
      backgroundColor: theme.palette.background.default,
      padding: theme.spacing(3),
    },
  }),
);

export default function PermanentDrawerLeft() {
  const classes = useStyles();

  return (
    <div className={classes.root}>
      <CssBaseline />
      <AppBar position="fixed" className={classes.appBar}>
        <Toolbar>
          <Typography variant="h6" noWrap>
            Permanent drawer
          </Typography>
        </Toolbar>
      </AppBar>
      <Drawer
        className={classes.drawer}
        variant="permanent"
        classes={{
          paper: classes.drawerPaper,
        }}
        anchor="left"
      >
        <div className={classes.toolbar} />
        <Divider />
        <List>
          {['Inbox', 'Starred', 'Send email', 'Drafts'].map((text, index) => (
            <ListItem button key={text}>
              <ListItemIcon>{index % 2 === 0 ? <InboxIcon /> : <MailIcon />}</ListItemIcon>
              <ListItemText primary={text} />
            </ListItem>
          ))}
        </List>
        <Divider />
        <List>
          {['All mail', 'Trash', 'Spam'].map((text, index) => (
            <ListItem button key={text}>
              <ListItemIcon>{index % 2 === 0 ? <InboxIcon /> : <MailIcon />}</ListItemIcon>
              <ListItemText primary={text} />
            </ListItem>
          ))}
        </List>
      </Drawer>
      <main className={classes.content}>

Answer 1

您应该指定一个高于 .MuiDrawer-paper 的 z-index 的 z-index，即 1200。

这里我将页脚 class 添加到 classes 样式对象，如下所示：

footer: {
      position: "fixed",
      left: "0",
      bottom: "0",
      width: "100%",
      backgroundColor: "red",
      color: "white",
      zIndex: "1201",
      textAlign: "center"
    }

然后将其分配给页脚元素：

  <div className={classes.footer}>footer</div>
