|
* If the field is in a <form>, construct the LoginForm from the form.
|
|
* Otherwise, create a LoginForm with a rootElement (wrapper) according to
|
|
* heuristics. Currently all <input> not in a <form> are one LoginForm but this
|
|
* shouldn't be relied upon as the heuristics may change to detect multiple
|
|
* "forms" (e.g. registration and login) on one page with a <form>.
|
|
*
|
|
* Note that two LoginForms created from the same field won't return the same LoginForm object.
|
|
* Use the `rootElement` property on the LoginForm as a key instead.

* @param {HTMLInputElement} aField - a password or username field in a document
|
|
* @return {LoginForm}
|
|
* @throws Error if aField isn't a password or username field in a document
