Another, more popular method since it works in browsers without requiring Flash to be installed is known as the iFrame method.
And here's how it works. Assuming we have a form with a file-type input field, the iFrame method of uploading files can be summarized in the following steps:. Since the submission takes place normal-style in an iframe, the parent window cannot inspect the response headers or status code from step 5 above , due to browser security restrictions.
There are ways around this , but as of this writing, they have not yet been pulled into the form. Furthermore, if a JS response was returned, it won't get executed in the parent window, because it was returned to the iframe.
We would thus need to manually check if the response was JS code instead of HTML markup or some other format , and execute it ourselves in step 7 above. Am using struts 1.
