  1. I ran into this confusion while trying to write a script for uploading a file using AJAX which would work in IE8. Apparently there is a hack to achieve this which involves the usage of iframes. What I've tried so far is submitting a form with just action attribute which redirects to another page. <form method="post" action="test.php"> <input type="text" name="name" /> <input type="submit" name="send" value="Send" /> </form> Even if I set the attribute to _self(default value), the page redirects to test.php and shows what ever is printed by the php script. Now when I set the target to _blank, the page test.php opens in a new tab and shows what ever is printed by the php script. <form method="post" action="test.php" target="_blank"> <input type="text" name="name" /> <input type="submit" name="send" value="Send" /> </form> And if I set the target to an iframe name present in the same page, the php response is printed in the iframe(which is the hack to upload a file) <form method="post" action="test.php" target="some_frame"> <input type="text" name="name" /> <input type="submit" name="send" value="Send" /> </form> <iframe name="some_frame" /> So what I want to know is how does the action and target attribute work once the form is submitted? When the target attribute is set to _self, the page redirects and then prints(action first and then target), but if the target attribute is set to _blank, first a new tab is opened and then the response is printed(first the target and then action) and when the target attribute is set to a frame_name, it prints within the frame(does it load the response from the page into the frame?). It would be really helpful if someone could assist me with a link or an explanation of the flow of a form submission, the order of execution of the action and target attributes and how do they work and in what order do they run.
