run setInterval for only 5 minutes?

Question

so I have the following code.

 setInterval(function(){
          steamOfferObj.getOffer({
              "tradeOfferId": tradeOfferID["tradeofferid"] // The tradeoffer id
          }, function(error, body) {
              if (error == null) {
                console.log(body);
                  if (body.response.offer.trade_offer_state == 3) {
                      return "Offer Accepted"
                  } else {
                      //on not accepted
                  }
              }
          });
      }, 5000);

basically it poles a steam trade offer to see if it has completed or not. However, this actually runs indefinitely, checking every 5 seconds until the program is time. What I was is for it to check every 5 seconds, for 5 minutes, after which it times out.

Any way I could go about doing that?

Answer 1

You can use setTimeout. For e.g

 var yourIntervalId = setInterval(function(){
          steamOfferObj.getOffer({
              "tradeOfferId": tradeOfferID["tradeofferid"] // The tradeoffer id
          }, function(error, body) {
              if (error == null) {
                console.log(body);
                  if (body.response.offer.trade_offer_state == 3) {
                      return "Offer Accepted"
                  } else {
                      //on not accepted
                  }
              }
          });
      }, 5000);

And here you clear the interval after 5 minutes (30000 ms)

setTimeout(function(){
    clearInterval(yourIntervalId);
}, 30000);

Answer 2

with interval I would to use something like this:

var start = Date.now();
var theInterval = setInterval(function () {
    if (Date.now() - start > 300000) {
        clearInterval(theInterval);
        return;
    }
    steamOfferObj.getOffer({
        "tradeOfferId": tradeOfferID.tradeofferid // The tradeoffer id
    }, function (error, body) {
        if (error === null) {
            console.log(body);
            if (body.response.offer.trade_offer_state == 3) {
                return "Offer Accepted";
            } else {
                //on not accepted
            }
        }
    });
}, 5000);

but in this case I better to use setTimeout, because you using async request:

var start = Date.now();

function getData() {
    if (Date.now() - start > 300000) {
        return;
    }
    steamOfferObj.getOffer({
        "tradeOfferId": tradeOfferID.tradeofferid // The tradeoffer id
    }, function (error, body) {
        setTimeout(getData, 5000);
        if (error === null) {
            console.log(body);
            if (body.response.offer.trade_offer_state == 3) {
                return "Offer Accepted";
            } else {
                //on not accepted
            }
        }
    });
}

getData();
