一、写法一
写法一中的 acceptanc…场景封装好的弹框按钮上加了个loading状态根据传入的值弹框提交的模块内容不一样。loading更新过后但是值没有变。
注写法一loading不更新写法二loading值更新。
一、写法一
写法一中的 acceptanceReject 函数是一个异步函数它会在异步操作完成后才会执行 finally 中的代码。这意味着 finally 中的 setLoading(false) 会在 acceptanceReject 函数中所有异步操作完成后才执行包括 await rejectDataDs.current?.validate()、await getTaskId(instanceId) 和 await postAcceptance(params)。
因此在写法一中即使在 acceptanceReject 函数中设置了 setLoading(true)但在 handleSubmit 函数中并没有等待 acceptanceReject 函数中的异步操作完成所以在 handleSubmit 中立即打印 loading 时可能仍然是旧值。 /** 提交 */const handleSubmit () {switch (type) {case one: oneReject();break;case two: twoReject();break;case three: fourReject();break;default:break;}};const one async () {setLoading(true);try {const validate await rejectDataDs.current?.validate();if (!validate) {return;}console.log(执行了嘛);const { id, instanceId } formDataDs.current?.toData();const taskIdValue await getTaskId(instanceId);const params: ItemAcceptance {...rejectDataDs.current?.toData(),id,instanceId,approveResult: N,taskId: taskIdValue?.[0]?.taskId,};debuggerconst res await postAcceptance(params);handleSuccess(res, acceptanceReject);} finally {setLoading(false);}};const two async () {const { id, instanceId } formDataDs.current?.toData();const { approveOpinion } rejectDataDs.current?.toData();const taskIdValue await getTaskId(instanceId);const params: DetermineParams {id,taskId: taskIdValue?.[0]?.taskId,instanceId,approveOpinion,approveResult: N,};const res await postDetermine(params);handleSuccess(res, decideReject);};const three async () {const {id,pkNo,instanceId,subInstanceId,} formDataDs.current?.toData();const { approveOpinion } rejectDataDs.current?.toData();const taskIdValue await getTaskId(subInstanceId);const params: ApprovalParams {id,pkNo,taskId: taskIdValue?.[0]?.taskId,instanceId,subInstanceId,approveResult: N,approveOpinion,};const res await postApprove(params);handleSuccess(res, approveReject);};
解决方法因为switch中忘记加异步await了。
二写法二
写法二中所有异步操作都在同一个函数中因此 setLoading(true) 和后续的异步操作是连续执行的所以可以在后续代码中获取到正确的 loading 值。 const handleSubmit async () {setLoading(true);try {const validate await rejectDataDs.current?.validate();if (!validate) {return;}const { id, instanceId } formDataDs.current?.toData();const taskIdValue await getTaskId(instanceId);const params: ItemAcceptance {...rejectDataDs.current?.toData(),id,instanceId,approveResult: N,taskId: taskIdValue?.[0]?.taskId,};console.log(loading, loading);const res await postAcceptance(params);handleSuccess(res, acceptanceReject);} finally {setLoading(false);}};
