Cannot get item id from EConItem

[vrtgn]

Hello.

 

I have the function below which gets an item id by calling the inventory, then seeing which item's name is correct and then returns the id, however when i return the ID, it does not show correctly: it shows undefined. I have tried both .assetid and .id But when i put in the function console.log(inventory.assetid) it logs the id, but when i call the function it doesnt return the id! Please halp thank you

 

function getID(itemname) {

    manager.getInventoryContents(440, 2 , true, function(err, inventory) {

      if (err) {

        console.log(err)

        return;

      } else {

        //console.log(inventory);

        for (var i = 0; i < inventory.length; i++) {

          if (inventory.market_hash_name === itemname) {

            return inventory.id;

          }

        }

      }

    })

You have a misunderstanding of how asynchronous code works in JavaScript. You need to pass a callback to getID and call it with the item ID you're looking for.

thanks for your quick reply

 

so like this?

 

function getID(itemname, callback) {

    manager.getInventoryContents(440, 2 , true, function(err, inventory) {

      if (err) {

        console.log(err)

        return;

      } else {

        //console.log(inventory);

        for (var i = 0; i < inventory.length; i++) {

          if (inventory.market_hash_name === itemname) {

            callback(inventory.id);

            return;

          }

        }

      }

    })

 

when calling :

getID("The Diamondback", function logID(id) {

//do something with id

})

Yep, that looks right. Although be aware that your callback function there is going to be called once for every item in your inventory that has a matching name. Put a return statement after the callback invocation to avoid that.
