IE11-Only Submit Bug

Question

I have a form on a page, something simple like:

<form action="form/submit" method="post">
    <button type="submit">Submit</button>
</form>

It works in every single browser, including older versions of IE, BUT in IE11 it fails, with the tab stuck in a continuous loading loop, never changing to the "thank you" page after submission. HOWEVER, if I open the console, it DOES work.

I'm aware of the console.log issues IE has, and already am using:

if (!window.console) {
    console = {
        log: function() {}
    };
}

to avoid it, which seems to be doing fine (as mentioned, every other IE works). Any insight as to where the issue might lie?

Answer 1

The problem appears when a form only has input elements without a name attribute (or no input elements). I found a reference to the bug here, though it also happens in desktop mode and not just metro mode as the link claims:

The fix is to create a dummy <input type="hidden" name="dummy" value="something"> field (with a name and value set) before submitting the form.

The bug happens in all compatibility modes offered by IE11.
