Reading in a text file in Javascript or Jquery

Question

Im new to Jquery and Javascript and im wondering how can i read information from a text file stored on my server and write back to this file again afterwards? I couldn't find much information after googling the problem

I would also like to read in the data line by line and store it in an array, is this possible?

Thanks, Matt

You can read files from the server with AJAX, but you can't write to them with JavaScript only. — Andre Backlund, Aug 19 '11 at 13:43

Maybe you can use ajax and read your file with backend code. Then return the file data back to client. What backend you prefer to use? — Waltsu, Aug 19 '11 at 13:45

I think you want to use some server side programming. If you want the data on the client, you can use javascript or jquery using some ajax solution.

You can read the file if server allows to get it via http but you cannot write to it

Read file can be done by simply $().load(url)

You could use a RESTful API in order to achieve this. Use HTTP GET (jQuery/AJAX) to get the contents of a file, edit what you wish, and use a HTTP PUT (jQuery/AJAX) to write the changes back to the server.

In a RESTful API, shouldn't a PUT request be used to update the file contents? – shesek Aug 19 '11 at 13:49
Ahh yes that would work better, but you could technically also use POST. I will update my answer accordingly. Thank you! – Norman Joyner Aug 19 '11 at 13:51
POST would technically work just as good, its just a matter of conforming to the REST standards – shesek Aug 20 '11 at 11:46

Read information - yes via ajax call. The javascript will get the text from the page - whatever it is html/php/asp and return it to the calling page.

Read line by line - it is possible if you write it yourself. There is no built-in function for this. But then the text should be divided by lines.

Write back - JavaScript can`t do it by itself. You need an ajax and serverside.
