<p>我在一個(gè)按鈕上呼叫「deleteDepartment」函數(shù)來(lái)刪除表格中的部門行。從表格中（我正在使用使用tanstack表的shancn表）獲取“selectedRows”鉤子中的選定行索引（將setSelectedRows作為prop傳遞給表格組件，該組件從表格中的rowSelection鉤子中獲取值）。 </p> <p><strong>問(wèn)題是</strong>：我能夠刪除前兩三行沒(méi)有任何問(wèn)題，但是當(dāng)我繼續(xù)刪除時(shí)，“rowSelection”狀態(tài)會(huì)保存來(lái)自上一個(gè)函數(shù)調(diào)用的值，並將其新增至目前選定的行數(shù)組。 </p> <p><em><strong>範(fàn)例</strong></em>：如果我刪除行['1']，下次我點(diǎn)擊按鈕刪除行2，那麼「rowSelection」的值應(yīng)該只是['2']，但它會(huì)加到先前的值中，如['1'，'2']。 </p> <p>我迷失在為什麼會(huì)發(fā)生這種行為。我認(rèn)為這可能是由於閉包和非同步性質(zhì)導(dǎo)致的，因此我使用了useCallback鉤子，但沒(méi)有用。請(qǐng)有更好知識(shí)的人幫忙</p> <pre class="brush:php;toolbar:false;">const DepartmentsAndRolesPage = () => { const [departments, setDepartments] = useState<departmentTypes[]>([]); const [selectedRows, setSelectedRows] = useState({}); const [rowIndexes, setRowIndexes] = useState<string[]>([]); useEffect(() => { getDepartment(); }, []); useEffect(() => { const indexesToAdd = Object.keys(selectedRows); setRowIndexes(indexesToAdd); }, [selectedRows]); const deleteDepartment = useCallback(async () => { if (rowIndexes.length === 0) { return; } if (rowIndexes.length === 1) { const filteredDepartment = departments[parseInt(rowIndexes[0])]; const id = filteredDepartment._id; const response = await axios.delete(`/api/department/delete/${id}`); if (response.statusText === "OK") { getDepartment(); setSelectedRows({}); } return; } if (rowIndexes.length > 1) { const departmentsToDelete = rowIndexes.map( (rowIndex) => departments[parseInt(rowIndex)]._id ); const response = await axios.post("/api/department/delete", { _id: departmentsToDelete, }); if (response.statusText === "OK") { getDepartment(); setSelectedRows({}); } return; } }, [departments, rowIndexes, toast]); Return (rest of the UI code here.... )</pre> <p><br /></p>
