Fail to read information from a web site using Google Apps Script

Question

I have tried to use "UrlFetchApp.Fetch" in google apps script to retrieve data from https://metoc.ndbc.noaa.gov/web/guest/jtwc ".

However, the information highlighted in red as shown here "web capture" cannot be captured in the file I downloaded. Please help, thanks.

var FILE_NAME = 'data.txt'
var Google_DRive_ID = 'your google drive folder id'
var RESOURCE_URL = 'https://metoc.ndbc.noaa.gov/web/guest/jtwc' 
var folder = DriveApp.getFolderById(Google_DRive_ID);
var exportUrl = RESOURCE_URL
var data = UrlFetchApp.fetch(exportUrl)
folder.createFile(FILE_NAME, data)

Answer 1

When I saw the source of https://metoc.ndbc.noaa.gov/web/guest/jtwc , it was found that the source you want is included in iframe with the id="_48_INSTANCE_0SiamlX2KcM6_iframe" . The source URL is src="/ProductFeeds-portlet/img/jtwc/html/coop.jsp?" . When your script is modified using the URL, it is as follows.

Modified script :

var root = "https://metoc.ndbc.noaa.gov";
var src = "/ProductFeeds-portlet/img/jtwc/html/coop.jsp?"; // You can also use "/ProductFeeds-portlet/img/jtwc/html/coop.jsp"

var FILE_NAME = 'data.txt'
var Google_DRive_ID = 'your google drive folder id'
var RESOURCE_URL = root + src;
var folder = DriveApp.getFolderById(Google_DRive_ID);
var exportUrl = RESOURCE_URL
var data = UrlFetchApp.fetch(exportUrl)
folder.createFile(FILE_NAME, data)

If I misunderstand your question, I'm sorry.
