A jQuery hasAttr() Equivalent. ref: https://css-tricks.com/snippets/jquery/make-an-jquery-hasattr/

• 1st way (I don't like it, it's long) but it suits for checking object has the field or not (2nd way is not applied)

var attr = $(this).attr('name');

// For some browsers, `attr` is undefined; for others, `attr` is false. Check for both.
if (typeof attr !== typeof undefined && attr !== false) {
  // Element has this attribute
}

• 2nd way: native javascript (love it)

$(this)[0].hasAttribute("name"); // love it, it's short

jQObject[0].hasAttribute("name");

• 3rd way

$(this).is('[name]');

$(this).filter("[name='choice']");
