jQueryでclassやidをワイルドカード指定

More than 5 years have passed since last update.

jQueryでワイルドカード指定取得方法、忘れがちなのでメモ。

<ul>
<li id="aaa1">TEST1</li>
<li id="aaa2">TEST2</li>
<li id="aaa3">TEST3</li>
</ul>
$(function(){
    $("[id^=aaa]").on("click",function(){
        console.log($(this).attr("id"));
    });
});

これのワイルドカード部分、id="aaa1"であれば「1」をclickイベント内で取りたい。
replace()で置換すれば良いんだろうけど、何かもっと簡単な方法があれば賢い人教えて~。
