Clearly the Enter key in a form submission, to avoid false submission.

Hello, I'm a front end developer from China, you can call me Peach.Than you for write this plug, it help me completed my project, but I find some problem, so I would like to ask your opinion. 

When I used the plug in a form, and I used the 'Enter' key to selected the items, the form will be submit, but the most user maybe just wan to selected the item instead of submit the form. So I think it should be change, what do you think?
