问题描述

我有一个菜单,它会有一个大小,当您单击按钮时,它会将宽度减少到50px

ie我将有一个带有按钮和图标的菜单,当单击按钮时将只出现图标

但我遇到了困难,如何减小div的宽度以及如何在语义网格上工作

编码:

function Menu() {
  const [open, setOpen] = useState(true); // declare new state variable "open" with setter
  const handleClick = e => {
    e.preventDefault();
    setOpen(!open);
  };
  return (
    <Grid style={{background: '#eee'}}>

    <Grid.Column computer={2} tablet={4} mobile={5} style={{background: '#000', padding:'0', height:'100vh'}}>

    <div style={{background:'#000', width:'100%', height:'100%'}}>

    </div>
    </Grid.Column>
    <Grid.Column width={14} style={{background: '#eee', padding:'0'}}>
          <Button icon onClick={handleClick}>
            <Icon name="align justify" />
          </Button>
    </Grid.Column>
   </Grid>
  );
}

css:

html,
body {
  height: 100%;
  margin: 0;
  padding: 0;
}
#root,
.App,
.ui.grid{
  height: 100vh !important;
  margin: 0 !important;
  padding:0 !important;
}

推荐答案

当点击按钮时打开状态改变时,可以减小div的宽度,请查看demo link

App.js

import React, { useState } from "react";
import { Grid, Button, Icon } from "semantic-ui-react";
import "./style.css";

function Menu() {
  const [open, setOpen] = useState(true); // declare new state variable "open" with setter

  const handleClick = e => {
    e.preventDefault();
    setOpen(!open);
  };

  return (
    <Grid style={{ background: "#eee" }}>
      <Grid.Column
        computer={2}
        tablet={4}
        mobile={5}
        style={{
          background: "#000",
          padding: "0",
          height: "100vh"
        }}
      >
        <div
          style={{
            background: "red",
            width: open ? "100%" : "calc(100% - 50px)",
            height: "100vh"
          }}
        />
      </Grid.Column>
      <Grid.Column
        computer={14}
        tablet={12}
        mobile={11}
        style={{ background: "#eee", padding: "0" }}
      >
        <Button icon onClick={handleClick}>
          <Icon name="align justify" />
        </Button>
      </Grid.Column>
    </Grid>
  );
}
export default Menu;
