Question

I want to upload an image and show it without refresh.

The method I know is to use an hidden iframe and set the target of the form to it.

Then return a piece of javascript from controller calling “parent.func()” to do something…

But here is my problem:

It seems that the javascript will not be executed unless the foreground knows the dataType is “script”, something like:

$.ajax {
    dataType:"script"
}

but when submit the form, I have to use

$("...").submit()

So I cannot specify the dataType….

Can anyone tell me what to do?…

Or can you tell me another way to achieve my goal:

upload a image and show it without refresh in Rails 3.2.0..
