Can anyone help me as i am stuck in creating a file(temporary) with extension(say .csv) in the local disk, i tried using ActiveX object but it works fine only in internet explorer,got a error when i tried with other browsers. By googling i got to know ActiveX works only in IE so it produces error when its tried in different browser.

    var fso, f1;
    fso = new ActiveXObject("Scripting.FileSystemObject");
    f1 = fso.GetFile("c:\\test.txt");
    alert(f1);

Can anyone suggest me with the alternative which can be very useful to.

• 1 There's no corresponding feature in other browsers. The nearest you can find is probably HTML5 localStorage. – Teemu Commented Feb 26, 2013 at 10:47
• Thanks for the reply,i want to store the data that es from the web service through ajax in a file created in the local disk using javascript. – pavan Commented Feb 26, 2013 at 10:52
• 1 Can I ask why as there may be a better option? If you are calling a web service, I assume you have access to some server side code / scripting where this task may be better suited and be truly cross browser patible. – webnoob Commented Feb 26, 2013 at 10:54

The problem you have is that browser implementations of ECMAScript (JavaScript) don't allow you to write to the clients' disk. Microsoft reverse-engineered JavaScript, and dubbed it JScript. Though the base is the same, MS added those ActiveX objects, and a piler (JScript can be piled, yes).

In short, JScript can be used for more than just browser tasks, so MS provided ActiveX objects to enable some form of I/O. The only thing you can do on browsers other than IE, is using HTML5's new DOM Storage objects. Teemu provided a link to the documentation for that

The other posts cover all the information about storing to the local machine using Html 5 so I won't go into any more detail about that but this is only going to work on Html 5 patible browsers (although most browsers are Html 5 patible now, I don't know your project requirements).

Another alternative would be to create / save the file using server side code (ASP.NET, PHP etc) and then provide a link to the user so they can download the file. You can still save this as a .csv file so that the user can open it in Excel after they have downloaded it.

Edit:

What I would do is change your web service so that it saves the file to disc (more info: here). Then instead of returning the file from the web service, return the Url to download it instead. You can then redirect the user to that link using JS.
