Question

我正在尝试在用户单击按钮时弹出一个表单对话框。我几乎完全从Dialog Material-UI站点获取了如何使用一个按钮来完成此操作，该按钮将用于打开Dialog和在Dialog中添加的TextField。这是使用Meteor和React。当我在服务器上运行时，我收到一个错误。有人知道Missing class properties transform.的含义吗？

代码

import React from 'react';
import Dialog from 'material-ui/Dialog';
import FlatButton from 'material-ui/FlatButton';
import FloatingActionButton from 'material-ui/FloatingActionButton';
import ContentAdd from 'material-ui/svg-icons/content/add';
import TextField from 'material-ui/TextField';

const style = {
  marginRight: "20px",
  position: "absolute",
  left: "80%",
  down: "80%",
};

export default class Events extends React.Component {
  state = {
    open: false,
  };

  handleOpen = () => {
    this.setState({open: true});
  };

  handleClose = () => {
    this.setState({open: false});
  };

  render() {
    const actions = [
          <FlatButton
            label="Cancel"
            primary={true}
            onTouchTap={this.handleClose}
          />,
          <FlatButton
            label="Submit"
            primary={true}
            keyboardFocused={true}
            onTouchTap={this.handleClose}
          />,
        ];

    return (
        <div>
          <h1>Events</h1>
          <FloatingActionButton style={style}>
            <ContentAdd />
          </FloatingActionButton>
          <Dialog
            title="Add Event"
            actions={actions}
            model={false}
            open={this.state.open}
            onRequestClose={this.handClose}
          >
            <TextField
              hintText="Hint Text"
              floatingLabelText="Floating Label Text"
            />
          </Dialog>
        </div>
    );
  }
}

请参阅我的其他答案以使此代码正常工作，但如果您愿意，也可以完全避免使用类语法。

import React from 'react';
import Dialog from 'material-ui/Dialog';
import FlatButton from 'material-ui/FlatButton';
import FloatingActionButton from 'material-ui/FloatingActionButton';
import ContentAdd from 'material-ui/svg-icons/content/add';
import TextField from 'material-ui/TextField';

const style = {
  marginRight: "20px",
  position: "absolute",
  left: "80%",
  down: "80%",
};


export default const Events = React.createClass({
  getInitialState: function () {
    return {
      open: false
    }
  },
  handleOpen: () => {
    this.setState({open: true});
  },

  handleClose: () => {
    this.setState({open: false});
  },

  render: function() {
    const actions = [
          <FlatButton
            label="Cancel"
            primary={true}
            onTouchTap={this.handleClose}
          />,
          <FlatButton
            label="Submit"
            primary={true}
            keyboardFocused={true}
            onTouchTap={this.handleClose}
          />,
        ];

    return (
        <div>
          <h1>Events</h1>
          <FloatingActionButton style={style}>
            <ContentAdd />
          </FloatingActionButton>
          <Dialog
            title="Add Event"
            actions={actions}
            model={false}
            open={this.state.open}
            onRequestClose={this.handClose}
          >
            <TextField
              hintText="Hint Text"
              floatingLabelText="Floating Label Text"
            />
          </Dialog>
        </div>
    );
  }
})

假设您正在使用babel，则需要class properties转换。它包含在stage 2 preset中，如果更可取的话。你在使用webpack捆绑吗？共享您的webpack配置，尤其是js中的jsx / loaders部分会有所帮助。

如何在Meteor / React中打开和关闭Material-UI对话框？
