letformdata=newFormData(form)console.log(formdata.get('fname'))console.log(formdata.get('lname')) i我们无法直接观察到 FormData 的值,需要使用.get方法来获取。 FormData 也可以被网络请求支持,例如我们可以把FormData对象作为 fetch 请求的body,直接发送 代码语言:javascript 代码运行次数:0 运行 AI代码解释 ...
const{isLoading,isError,data,error}=useQuery(['todos',status,page],()=>fetch(`/api/todos?status=${status}&page=${page}`).then(response=>response.json()),); 这里我们将queryKey替换成了一个可以数组['todos', status, page],这样一旦status、page参数发生变更的时候,React Query 通过queryKey的...
