Get Data From A Promise
I'm working with Tabletop.js to get data from my Google Spreadsheet. In the function, I've invoked a Promise. The only problem is I can't get the data(which is an Array) out of the
Solution 1:
You seem to have a couple of issues here..
Firstly, you have showInfo().then
, I'm pretty sure you meant to do -> getData().then(
Your next problem is your getData function,. like @ChrisG said your just resolving a promise instantly here, below is more likely what you meant to do.
functiongetData() {
returnnewPromise((resolve) => {
Tabletop.init({key: publicSpreadsheetUrl,
callback: function (data, tabletop) { resolve(showInfo(data, tabletop)); },
simpleSheet: true})
})
}
Lastly your showInfo is not doing anything async
so it can be simplified to ->
functionshowInfo(data, tabletop) {
console.log('showInfo active');
arrayWithData.push(...data);
console.log(arrayWithData, 'data is here')
return arrayWithData;
}
One last thing, there is no error checking here, normally callbacks have some way to inform you of an error condition, then you could also add the reject
handler.
