QUESTION
I'm trying to learn async functions and am struggling to get the following to work.
...ANSWER
Answered 2022-Mar-22 at 16:45there are two things:
first, the code in the then()
block is returned to price
variable that isn't returned
second, var price = get_price(symbol);
the function call is not using await
so if you log that you will get the promise instead of the value.
you need to return
the axios call and await
it when using the function elsewhere

QUESTION
I am trying to build a web scraper to get informations about some products and store them inside a database. I'm getting the HTML source code with Nightmare (because javascript code has to run on the server before the page content is created) then I'm parsing that source with Cheerio. Once I do the parsing there are some images I have to download for the products. I have a simple download function and, based on if the image which I'm trying to download is available or not on the server, I'd like to return a string (or an array of strings) containing either the image name (which I downloaded) or a default image name from my computer. I tried calling the download function as a promise, I tried passing Promise.all() when I know there are multiple images to download, but to no avail. While I'm positive my code is working (the images are downloaded as should, the final object looks great at almost every property and value), it is the images properties fields which, when I'm printing the object to the console, still holds [Promise] / [ Promise { } ] and I'm not quite sure how to solve this matter. I'm positive those promises resolve, but they're not resolved when I'm outputting the resulting object to the console. And that's a problem, 'cause I have to pass that object to be stored in the database and I don't think they'll be resolved then.
The code (minus the exact links) is down below:
...ANSWER
Answered 2022-Jan-04 at 23:40You are getting an array of Promises returned by the map() method, so you will need to use Promise.all() or one of its variants.
For example, here you get the array of promises of "images", then you use Promise.all() to wait for all promises to be resolved, and finally you chain a then() to use the values.
QUESTION
I can't use map function in the right way within google apps script while scraping two fields—movie name
and image
— from a webpage.
ANSWER
Answered 2021-Dec-24 at 22:31You can still use map
but you need to change the way you access the element.
The reason it is undefined
is because you were trying to do a find
on the index
value. Upon testing, container on each element returns [index, item]
instead of [item, index]
. Specifying you want the 2nd element will fix the issue.

QUESTION
I'm trying to use the value of a variable inside the element selector that is p:nth-child(0)
, instead of a number that is 0, I want to put the value of a variable, in this case, It is i
of for loop.
But It is giving an error
...ANSWER
Answered 2021-Dec-10 at 16:18IDK if it's the whole problem, but you are re-declaring the variables "gameSizePStatus" and "gameSizeP" in your loop. That's likely causing the "text" variable line to look for an element that doesn't exist at too high of a "i" value. This would also probably cause an error on your "gameSize" line for trying to find an empty string value. You should also do a null check before calling ".text()" so you don't throw an error when you reach an element that doesn't exist.
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Optional_chaining
Rereading further, you have a comma in your for loop declaration instead of a semi-colon with an extra semi-colon after the "i++", and you aren't doing the loop anyway, since you assign "gameSizePStatus" to false and the loop wants it to be true. This means "gameSizeP" is empty when trying to run "$('p:nth-child('+gameSizeP+')')". Even if this doesn't error out, it would likely return undefined
and throw an error on the ".text()".
Since I'm rewriting my comments as an answer, I'll also say that "gameSizePStatus" is an unnecessary variable. You can use other/better/simpler/cleaner logic to do the same thing. And you don't need to assign a value to "gameSizeP" when declaring it. This makes checking it's value easier later.
Here's my re-write of your code. I'm only including the relevant if
statement for clarity.
QUESTION
I just started learning about web scraping and I found this tutorial: https://www.mundojs.com.br/2020/05/25/criando-um-web-scraper-com-nodejs/
It works fine, however I'm trying to get different elements from the same webpage: https://ge.globo.com/futebol/brasileirao-serie-a/
With the group of classes of the tutorial it brings all the elements with the selected class, but with other classes it doesn't work:
As can be seen all fifty elements with the class ranking-item-wrapper
are returned, but if I select elements with the class lista-jogos__jogo
it doesn't return anything:
I don't get why I'm getting this error, since I'm doing exectly the same thing as it is done in the tutorial.
Here is a short version of the code:
...ANSWER
Answered 2021-Nov-27 at 22:45It looks like those elements are being added with JavaScript when the page is loaded.
If you inspect the page in your browser with JavaScript disabled you can see that those elements don't exist, so they also wont exist when you pull down the page with Cheerio.
