Initializing any widget like:

var options = Object.create(null);
options.label = 'Button Label';
$('#button').button(options);

throws an error like:

input[inputIndex].hasOwnProperty is not a function

Runnable example: ​http://jsbin.com/juneboqere/edit?html,js,output Responsible code: ​https://github.com/jquery/jquery-ui/blob/ef2e9bab92ae898311baa295590cd487d9071319/ui/widget.js#L186

jQuery UI must not rely on hasOwnProperty of passed objects, but must instead use Object.prototype.hasOwnProperty to avoid this problem.

jQuery's own extend doesn't have this problem and the code below works:

var options = Object.create(null);
options.label = 'Button Label';
$('#button').button($.extend({}, options));

I have submitted a PR to jquery-rails, but they said that the localization fir jq-ui is to be done here. How can i submit a PR for the same?

The changes can be found here: ​https://github.com/vraravam/jquery-ui-rails/commit/d6fab056795d99e8b840f5e2aa8556371ec0271c

In the example for autocomplete, at ​https://jqueryui.com/autocomplete/, the style link to jQuery is missing the https: at the beginning. Not the biggest deal, but in case someone is doing a copy paste of the example code it will not work as shown.
