let found = false;
axios
.get(link)
.then((response) => {
response.data.map((element) => {
if (element.id_ticket.toString() === nbTicket) found = true;
});
console.log(found);
});
so im trying to get data from the api and see if the value of 'nbTicket' is in the returned data and that is done using the 'found' variable so if i log the 'found' variable value outside the .then method it stays false even if the value exists and when i do it iside the .then methods it gives the correct value
let found = false;
axios
.get(link)
.then((response) => {
response.data.map((element) => {
if (element.id_ticket.toString() === nbTicket) found = true;
});
});
console.log(found);
your console.log(found); is executing is executing before you fetch data from api you can call it inside then or use async await if you want to call console.log(found); after you get data from api
Your supposed to use async/await strategy, because console.log happens after Axios request:
async function getNbTicket(){
let found = false;
const { data } = await axios.get(link);
data.data.map((element) => {
if (element.id_ticket.toString() === nbTicket) found = true;
});
return found;
}
This is normal behavior, because of the async and sync.
you have two options first one is to wrap your code inside a async function
const checkIfTicketIsFound = async () => {
let found = false;
const { data } = await axios.get(link);
data.map((element) => {
if (element.id_ticket.toString() === nbTicket) found = true;
})
console.log(found)
return found
}
Or
you need to print inside the then chain
let found = false;
axios
.get(link)
.then((response) => {
response.data.map((element) => {
if (element.id_ticket.toString() === nbTicket) found = true;
});
console.log(found);
});
