- These are the methods I know of:
- + Set the form's [`target` attribute][1] to `_blank`.
- + Add [`submit` event][2] listeners (e.g., [this SO thread][3]).
- In the proprietary web app that I have to work with, **every** form submission pops up a new browser window. Some of these are easily preventable by replacing the JavaScript spaghetti code with submitting the forms directly with [`submit()`][4], but there is one that stumps me:
- There is a form that `POST`s to `url_a`, the form has no `target` attribute or `submit` event listener, and after submitting a new window pops on `url_b` whose parts are not referenced anywhere in the originating page, and I also couldn't find any reference to it in the network request and response. The page's `<body>` element has a `load` event listener attached, but none of the functions listed there seem relevant.
- Am I missing something basic?

What can cause an HTML form submission result in a new pop-up window?
