我正忙于尝试 Blueprint.js 和 MultiSelect 组件,我不知道它仍在积极开发中:http: //blueprintjs.com/docs/#labs.multiselect
我从未使用过 TypeScript,据说
// Select<T> is a generic component to work with your data types.
// In TypeScript, you must first obtain a non-generic reference:
const FilmSelect = Select.ofType<Film>();
所以我的问题是,是否可以在不使用 TypeScript 的情况下在 Javascript 中使用这个组件?
我的 react 组件目前没有渲染,出现以下错误:
multiSelect.js?64c9:37 Uncaught TypeError: Cannot read property 'map' of undefined
组件定义为:
import React from 'react';
import Flexbox from 'flexbox-react';
import {Dialog, Button, Intent} from '@blueprintjs/core';
import {MultiSelect} from '@blueprintjs/labs';
import {inject, observer} from 'mobx-react';
import Avatar from 'react-avatar';
@inject('AccountRelationshipsStore', 'AccountUsersStore', 'ToastStore')@observer
export default class AccountRelationshipsNewRelationship extends React.Component {
constructor(props) {
super(props);
this.state = ({isSubmitting: false});
}
renderUser(handleClick, isActive, user) {
return (
<span>{user.fullName}</span>
);
}
renderTag(user) {
return user.fullName;
}
handleItemSelect(item) {
console.log(item);
}
render() {
return (
