jeecgboot-vue3-AntDesign笔记(十四)——异步调用后端
作者:互联网
错误操作
- handler
function onDeleteRow(props) {
console.log("on delete one row",props.row.id);
deleteOne({"id":props.row.id});
console.log("delete succ.");
loadData();//加载删除后的数据
}
- api
export const deleteOne = (params) => {
return defHttp.delete({url: Api.deleteOne, params}, {joinParamsToUrl: true});
}
操作后发现后台记录已删除,前端也执行了查询,但查到的仍然为原来的记录,因为js异步执行的,在后端还没有删除掉之前先执行了查询。
正确操作
- handler
function onDeleteRow(props) {
console.log("on delete one row",props.row.id);
deleteOne({"id":props.row.id},()=>{
console.log("delete succ.")
loadData();//加载删除后的数据
});
}
- api调用
export const deleteOne = (params,handleSuccess) => {
return defHttp.delete({url: Api.deleteOne, params}, {joinParamsToUrl: true}).then(() => {
handleSuccess();
});
}
更改为执行删除成功后回调查询方法,则当服务端返回删除操作成功后,前端再执行查询操作,查询到的是删除后的数据。
