在 Google Sheets 中制作自定义 function，代码在工作表之外工作，但不在工作表中

Question

So I'm writing a custom function for Google sheets which is supposed to take a single row or cells, produce a 1 dimensional array and use that data to create a URL. This is basically so I can help my friends track the prices of an item in a video game.

I have ran the code in a javascript environment outside of Google Sheets and everything acted as expected. But when I put the code in the script editor, it runs with unexpected behavior. The range of cells will always be 1 row by 13 columns but some of the columns may be void so the script is supposed to truncate the array of values so that there are no empty indexes. Then it is supposed to insert a "." between each value as it is concatenated into a string to produce the final URL. For some reason it does not remove any values and the "." are ","s when the URL is created in the cell.

Here is the code:

function STONKLINK(prices, premrkt) {
  var webLink = "https://turnipprophet.io?prices=";
  var priceLink = "";

  for (i = (prices.length - 1); prices[i] == 0; i--){
    prices.pop();
  }
  for (i = 0; i < prices.length; i++) {
    priceLink = (priceLink + prices[i] + ".") 
  }

  priceLink = priceLink.substring(0, priceLink.length - 1);

  if (premrkt == "N/A") {
    webLink = webLink + priceLink;
  } else if (premrkt == "Fluctuating") {
    webLink = webLink + priceLink + "&pattern=0";
  } else if (premrkt == "Small Spike") {
    webLink = webLink + priceLink + "&pattern=3";
  } else if (premrkt == "Large Spike") {
    webLink = webLink + priceLink + "&pattern=1";
  } else if (premrkt == "Decreasing") {
    webLink = webLink + priceLink + "&pattern=2";
  }
  return webLink;

}

Any help is very much appreciated. Thank you so much.

EDIT: While I still do not understand why this is happening, and I would like to understand, I have added a simple work around. By adding this line of code

webLink = webLink.replace(/,/g, ".");

before the return , all the commas will be replaced with dots. Still, any insight into the problem will be much appreciated. Thank you again.

When you store values in Spreadsheets, the values which have a , are considered to be strings whilst the ones which have a . will be considered to be numbers .

So for example, if you have these values stored in the B column:

If you log the typeof(val1) and typeof(val2) (where val1 and val2 are the values stored in B1 respectively B2 ), this is what you will get:

So the issue you were encountering is due to this fact. The values you have stored in your sheet are numbers and when you try to build the webLink string they are converted into strings - therefore, the . for a number becomes , .
