How to find out if URI contains document?

I want to open a window in the browser in the following manner:

 window.open('/Item/Article/' + result, 'ItemArticle', 'resizable=yes,scrollbars=yes,height=' + res.height + ',width=' + res.width + ',left=0', null);

however if the above dynamic URI does not contain a document no Iframe will be created. Is there a way that I could check whether the item in the URI exists before I attempt to open an iframe, this way I would be able to inform the user that there is no document found.

Let the window open, then use a 404 page for letting the user know that no document was found.

If you really want to do it another way – do an AJAX request like @Raymond suggests, then if you get a successful response, open the window. I can't recommend this however, it means the client will be doing at least one more or less useless request.

You can check if the document exists by performing an AJAX request. If it succeeds, you know the URL is valid.

http://api.jquery.com/jQuery.ajax/

var docURL = '/Item/Article/' + result;
$.ajax({
    type: 'HEAD',
    url: docURL,
    success: function () {
        window.open('..');
    }
});
