问题描述
这是我正在尝试通过Google电子表格图表上的JavaScript工具运行的功能,该功能当前在4个不同的网站上均有效,在此示例中:
This is the function I'm trying to run through the JavaScript Tool on my Google Spreadsheet chart, the function is currently working on 4 different websites, where in this example:
$ id是我的电子表格单元格(belacoin)中导入的值
$id is the imported value from my spreadsheet cell (belacoin)
function CoinmarketcapPrice($id) {
var response = UrlFetchApp.fetch("https://api.coinmarketcap.com/v1/ticker/" + $id);
var html = JSON.parse(response.getContentText());
try
{
return parseFloat(html["price_btc"]);
}
catch(err)
{
return null;
}
}
这是UrlFetch返回的内容:
this is what that UrlFetch returns:
[
{
"id": "belacoin",
"name": "BelaCoin",
"symbol": "BELA",
"rank": "176",
"price_usd": "0.212823",
