Displaying a variable from file

Copy linkTweet thisAlerts:
Oct 27.2008

I have a text file named sample.txt. Inside of sample.txt is the value10/20/2008. I want to call that file using javascript to display that value at the top of my page.

For example – if the date stored in the sample.txt was 10/20/2008, at the top of my page I want it to display:

Page last updated: 10/20/2008

@ryanmkiltauthorOct 27.2008 — I only want to use javascript and HTML by doing this. I'm almost positive there is a way.

@toicontienOct 27.2008 — You can use a hidden IFRAME and set its src attribute to the text file. Again, the TXT file must come from the same domain as the web page.

Once you've got the IFRAME pointing to the TXT file, give the IFRAME a name. Then use JavaScript to get the innerHTML of the IFRAME's document object, and that should be what you need.

BTW, AJAX is JavaScript. It's just a JavaScript programming pattern.

Another thought, seeing as some browsers might prompt the user to download the TXT file in the IFRAME, is to save it as an HTML file. Then you're sure to be able to read the HTML file with JavaScript.

Success!
