In this lesson we'll show how to use the AutoSizer component from react-virtualized to automatically measure the width/height of our content area. We'll then use theList component to render our set of data as a virtualized list into the DOM using win
In this lesson we'll use CellMeasurer and CellMeasurerCache to automatically calculate and cache the height of a row. This will allow us to remove the predefined rowHeight on list and allow for dynamically sized rows. import React, {Component} from '
import React from 'react'; import {message} from 'antd' import vis from 'vis'; import {api as http} from '../../fetch'; let relation = { nodes: [], edges: [] }; //设置关联图的数据(nodes为节点.edges为关联线) const visDate={ //后端返回的数据格式 nodes:[ { image:IconDomai
现在让我们看看大致的流程: React 可以触发 Action,比如按钮点击按钮. Action 是对象,包含一个类型以及相关的数据,通过 Store 的 dispatch() 函数发送到 Store. Store 接收 Action 的数据并将其连同当前的 state 树(state 树是包含所有 state 的一种特殊的数据结构,是一个单一的对象)发给 Reducer. Reducer 是一个多个函数的合成函数(当然一般都是),它接收一个之前的 state 和一个 Action:并基于此 A
