在React material-ui上显示对话框

Question

I'm using material-ui's Dialog component for my React application. How do I set my component to a variable so that I can call the onShow() method?

Answer 1

When adding the Dialog component, just add a ref to it ( ref="dialog" for example):

<Dialog ref="dialog" title="..." actions="...">
  dialog content
</Dialog>

And then you can reference it from your owner component code by using this.refs.dialog.onShow(...) .

The Dialog component page actually uses refs behind the scenes, as you can see from its source code .

Answer 2

I recommend reading Dan Abramov's answer on how to implement a modal in React.

In order to use material-ui dialog you can replace the DeletePostModal in his example with the following:

import { deletePost, hideModal } from '../actions';
import React, {Component} from 'react';
import {connect} from "react-redux";
import {Button, Dialog, DialogActions, DialogTitle} from "material-ui";
import PropTypes from 'prop-types';

const DeletePostModal = ({ post, dispatch }) => (
  <Dialog open={true}>
       <DialogTitle>Delete post {post.name}?</DialogTitle>
            <DialogActions>
                 <button onClick={() => {
                      dispatch(deletePost(post.id)).then(() => {
                           dispatch(hideModal());
                      });
                  }}>
                        Yes
                  </button>
                  <button onClick={() => dispatch(hideModal())}>
                        Nope
                  </button>
        </DialogActions>
   </Dialog>
)

export default connect(
  (state, ownProps) => ({
    post: state.postsById[ownProps.postId]
  })
)(DeletePostModal)
