netteForms: Nette.toggle back compatibility

[solcik]

Version: 3.0.1

Bug Description

The bug was introduced in this commit d862717#diff-31d0814231016345eaa29e9607fc0c15R658

Nette.toggle back compatibility (regex) for id selector is broken.

As per https://www.w3.org/TR/html4/types.html#type-id

ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons (":"), and periods (".").

Steps To Reproduce

Nette forms ids are generated - for example: "frm-exampleForm-form-exampleField". This id is not supported by regex.

Expected Behavior

Proper back compatibility.

Possible Solution

Change the regex to:

/^\w[\w\d-_.,]*$/
