jquery,获取标签ID号

Question

我有这个链接:

<a id = "link_1" href = "#">Cars</a>
<a id = "link_2" href = "#">Colors</a>
<a id = "link_3" href = "#">Users</a>
<a id = "link_4" href = "#">News</a>

如何获取我点击的ID号码？例如,我推动链接汽车,我希望获得1,推送用户,获得3号.

谢谢

这样做:

$('a').click(function(){
  alert(this.id.split("_")[1]);
});
