I am trying to use useFetch
to get API data and index to get a specific value.
This is the current code:
const { isLoading, error, data } = useFetch("https://public-api.solscan.io/account/tokens?account=C9XzDbZrZkJ75EvEeb641PQ5Q9kDiN2nFugdyAXqGip1");
const dataStarsStaked = JSON.stringify(data, ["0", "tokenAddress", "tokenAmount", "uiAmount"], 0);
which returns data
:
[{"tokenAddress":"4q5UBXJxE91BZKX548qhU8i5QBWvZdXzS3RZwfTgLQda","tokenAmount":{"uiAmount":253847.899902}},{"tokenAddress":"HCgybxq5Upy8Mccihrp7EsmwwFqYZtrHrsmsKwtGXLgW","tokenAmount":{"uiAmount":6864373.022357}},{"tokenAddress":"HkNK7BL5pSUUzc6ns1mHW5JnzbSG4S9u2QdR3cUuyzSa","tokenAmount":{"uiAmount":678}}]
I am trying to get the value of uiAmount of tokenAddress: HCgybxq5Upy8Mccihrp7EsmwwFqYZtrHrsmsKwtGXLgW
. How do I do this? I am not sure how to index this. Thanks!

You can search the data array:
data.find(x => x.tokenAddress === "HCgybxq5Upy8Mccihrp7EsmwwFqYZtrHrsmsKwtGXLgW");
To get rid of the typescript errors, you need to define types (use something similar to this, but change any[]
to the array of object types the api is returning):
interface YourFetchResult {
data: any[];
isLoading: boolean;
error?: string;
}
const { isLoading, error, data }: FetchResult = useFetch(...)
CodePudding user response:
you need to apply a for loop and have a condition that detects the string see below
let x = [{"tokenAddress":"4q5UBXJxE91BZKX548qhU8i5QBWvZdXzS3RZwfTgLQda","tokenAmount":{"uiAmount":253847.899902}},{"tokenAddress":"HCgybxq5Upy8Mccihrp7EsmwwFqYZtrHrsmsKwtGXLgW","tokenAmount":{"uiAmount":6864373.022357}},{"tokenAddress":"HkNK7BL5pSUUzc6ns1mHW5JnzbSG4S9u2QdR3cUuyzSa","tokenAmount":{"uiAmount":678}}]
for (let i = 0; i < x.length; i ) {
if(x[i].tokenAddress==="HCgybxq5Upy8Mccihrp7EsmwwFqYZtrHrsmsKwtGXLgW") {
console.log(x[i].tokenAmount)
}
}
