Question

I need the complete code for uploading a file in dojo.
Especially the ajax call and its button creation, and its url must get stored into database. I use the following code, but it’s not working:

function uploadPicture()
{
    alert("yes");
    var xhrArgs = {
        url:"/service/ajax/uploadPictureToOption/",                 
        form: dojo.byId("optionsForm"),
        handleAs: "json",
        content :{},
        load: function(response, ioArgs){
            if (response == "failed")
            {
                alert("Failed");
                window.location.reload();
            }
            else if (response == "success")
            {
                window.location.reload();
            }
            else
            {
                alert("Successfully deleted");
                window.location.reload();
            }
        },
    }
    var deferred = dojo.xhrPost(xhrArgs);
}

Answer 1

to begin with your idea for a file upload is currently imposible using the xhr modules of dojo (AKA AJAX[only handdles plain text]).
The closest posible thing you can do is to subbmit the form to a hidden iframe.

EDIT

The code for a hidden iframe should be something like this:

<form method=”post” action=”formProcess.php” target=”hiddenIFrame”>
<input type=”file” name=”test” />
<input type="submit" value="Submit">
</form>

<iframe style=”width:0px;height:0px;border:0px;” name=hiddenIFrame />

you can also search in google as “hidden iframe submit”
