我在 Javascript 中有一個(gè)長(zhǎng)期運(yùn)行的任務(wù)。React 應(yīng)該在任務(wù)之間的幾個(gè)點(diǎn)重新渲染組件。但它僅在整個(gè)任務(wù)結(jié)束時(shí)重新渲染。如何讓 React 在所有setState()調(diào)用中重新渲染頁(yè)面？一個(gè)簡(jiǎn)化的例子：setStatePromise = (state) => new Promise(resolve => {    this.setState(state, () => resolve());});longRunningTask = async () => {    await this.setStatePromise({progress: 1}); // not shown to the user    await doMuchWork();    await this.setStatePromise({progress: 2}); // not shown to the user    await doEvenMoreWork();    await this.setStatePromise({progress: 3}); // shown to the user when everything is done};onButtonClick = async () => {    await this.longRunningTask();}這是一個(gè)顯示問題的工作示例：https://codesandbox.io/s/intelligent-cori-31qn5我之前使用的解決方法是：setStatePromise = (state) => new Promise(resolve => {    this.setState(state, () => {        setTimeout(() => resolve(), 1);    });});
