JQuery Marine Weather

[Nichols Family]

Alex;

I have a autoupdating file located at;

http://www.ndbc.noaa.gov/data/latest_obs/latest_obs.txt

I want to pull the data from 42060 into a readable format so the result should be;

weather for station “stn 42060” winds from “WDIR” at speed “WSPD” Wave height “WVHT”.

do you have any ideas to get me started in the right path? I understand this is a text file but I have been unable to append and parse the data correctly. Thanks.

Kevin

Hi,
This URL throw this response when I try to get the file with ajax:

Failed to load https://www.ndbc.noaa.gov/data/latest_obs/latest_obs.txt: No ‘Access-Control-Allow-Origin’ header is present on the requested resource. Origin ‘https://spjsblog.sharepoint.com’ is therefore not allowed access.

Do you control this datasoruce? – if you bring up the dev console and type in this (you need jQuery so you should run the code in the console from a DFFS enabled form):

jQuery.get("https://www.ndbc.noaa.gov/data/latest_obs/latest_obs.txt", function( data ) {
    console.log(data)
});

Are you able to read it?

If you do, I can help you parse it like this:

var colDescr = [];
jQuery.get("/path to the file/latest_obs.txt", function( data ) {
    jQuery.each(data.split("\n"),function(i,line){
		if(i===1){
			colDescr = line.split(/ +/);
			colDescr[0] = "";
        }else{
			var cols = line.split(/ +/);
			console.log("Weather from station \""+ cols[0] + colDescr[0]+"\" winds from \""+ cols[8] + colDescr[8]+"\" at speed \""+ cols[9] + colDescr[9] +"\" Wave height \"" +cols[11] + colDescr[11] + "\"");
        }
    });		
});

This snippet outputs to the developer console like the attached image show.
