Country Data Primer Tutorial<\/p><\/div>\n

The other day we came upon a great Open Licence data source concerning a country data “cow.txt”<\/a> flat file with semicolon column separators, thanks to the heads up at this great link<\/a>.<\/p>\n

With today’s blog posting we start out writing a Javascript and HTML web application using “cow.txt” hosted in an HTML iframe element arrangement, and relying on its “onload” event Javascript language …<\/p>\n

… that dovetails with HTML …<\/p>\n


\n<iframe style=display:none; id=myif onload=checkif(this,document.getElementById('lang').value); src='\/cow.txt'><\/iframe>
\n<\/code><\/p>\n

… and imagine we’ll extend its functionality into the near future, onto its proof of concept country_data.html<\/a> Country Data<\/a> web application start …<\/p>\n
