javascript - 如何获取span标签的id

Question

我有一组 span 标签，例如 .

 <span id="q_1" >D1</span>
 <span id="q_2" >D2</span>
 <span id="q_3" >D3</span>

如何借助jquery获取span标签的id。数字1,2,3是运行时生成的。所以我的基本结构是

<span id="q_" ></span>

Answer 1

$("span").each(function(){
     var thisId = $(this).attr('id');
     // Do whatever you want with the Id, and go on to the next one.
});
