jquery clone，設置屬性並追加

Question

我想克隆一個元素，設置元素屬性，之後附加到面板。什麼是正確的方法來做到這一點？

var $EleAClone = $('EleA')[0].clone();//here was error. 

$EleAClone.attr("Key", "KeyValue"); 

$('#somepanel').append($EleAClone); 

Answer 1

var $EleAClone = $('EleA').clone();//here was error. 

錯誤選擇$('EleA') - >$('#EleA')或$('.EleA')
