在 immer 中使用 produce 更新数组值
Update the array values using produce in immer
我正在尝试使用 produce in immer 更新数组值,但 draft 对我来说是未定义的。你能告诉我我做错了什么吗?
export const getCustomers = (customers) => (dispatch, getState) => {
const activeCustomers = produce(customers, (draft) => {
for (let i = 0; i < customers.length; i += 1) {
draft.customers[i].position= i;
}
});
//I keep getting that error that draft.customers[i] is undefined
我做错了什么。不断收到 draft.customers[i] 未定义
的错误
好吧,草稿是 customers
自己的 clone
,因此不包括客户,
试试这个:
export const getCustomers = (customers) => (dispatch, getState) => {
const activeCustomers = produce(customers, (draft) => {
for (let i = 0; i < draft.length; i ++) {
draft[i].position= i;
}
});
