如何从父组件打开Material UI Modal?

问题描述

这是我的父组件:

import React from 'react';
import ChildModal from 'ChildModal';

const ParentComponent = () => (
  <div>
    <span>Click </span>
    <a>HERE TO OPEN MODAL</a>
  <div>
);

这是我的孩子部分:

import React, { useState } from "react";
import { Modal, Backdrop, Fade } from "@material-ui/core";

const ChildModal = () => {
  const [open, setOpen] = useState(false);

  const handleOpen = () => {
    setOpen(true);
  };

  const handleClose = () => {
    setOpen(false);
  };

  return (
    <div>
      <button type="button" onClick={handleOpen}>
        react-transition-group
      </button>
      <Modal
        aria-labelledby="transition-modal-title"
        aria-describedby="transition-modal-description"
        className="modal"
        open={open}
        onClose={handleClose}
        closeAfterTransition
        BackdropComponent={Backdrop}
        BackdropProps={{
          timeout: 500
        }}
      >
        <Fade in={open}>
          <div className="paper">
            <h2 id="transition-modal-title">Transition modal</h2>
            <p id="transition-modal-description">
              react-transition-group animates me.
            </p>
          </div>
        </Fade>
      </Modal>
    </div>
  );
};

因此，基本上，如何从父组件打开模式?我应该通过道具还是以其他方式处理 open 状态?

So, basically, how can I open modal from parent component?Should I pass a prop or handle open state in some other matter?

还可以使用 a 标签完成此操作吗?我需要使用它来保持一致，这不是实际情况，但您会明白这一点.:)

Also, can this be done with a tag? I need to use it to keep it in the same line, and this is not real-world scenario, but you'll get the point. :)

谢谢.

推荐答案

import React from 'react';
import ChildModal from 'ChildModal';

const ParentComponent = () => (

      const [open, setOpen] = useState(false);

      const handleOpen = () => {
        setOpen(true);
      };

      const handleClose = () => {
        setOpen(false);
      };

      return (
          <div>
            <input type="button" onClick={handleOpen}>CLICK HERE TO OPEN MODAL</input>
            <ChildModal open={open} onClose={handleClose}
          <div>
        );

在Modal中设置像这样的props属性以设置open和handleClose:

In Modal set props attributes like this to set open and handleClose :

<Modal
        aria-labelledby="transition-modal-title"
        aria-describedby="transition-modal-description"
        className="modal"
        {...props}
        closeAfterTransition
        BackdropComponent={Backdrop}
        BackdropProps={{
        timeout: 500
        }}
    >
        <Fade in={this.props.modalState}>
        <div className="paper">
            <h2 id="transition-modal-title">Transition modal</h2>
            <p id="transition-modal-description">
            react-transition-group animates me.
            </p>
        </div>
        </Fade>
    </Modal>
