1、Get the attribute, check the value
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}
2、Native JavaScript has a way
$(this)[0].hasAttribute("name");jQObject[0].hasAttribute("name");
3、Filter the selection
$(this).is('[name]');$(this).filter("[name='choice']");
