我有五个 buttons
和 bootstrap close
,我将 onclick
事件处理程序添加到 alert()
next sibiling文本。问题是它仅在第一个关闭按钮上显示 alert()
。
http://jsfiddle.net/4cz57mge/
<script>
$("#closenotify").click(function(){
alert($(this).next().text());
});
</script>
我是 JQuery 的新手,让我知道我在这里缺少什么?
谢谢
这是因为您使用的是唯一 ID,所以 jQuery 会在它找到的第一个 ID 处停止。继续并更改您的代码以使用一个类,它会起作用。您已经为每个添加了一个 close
类,因此只需将其更改为以下内容即可。
附带说明一下,您的 jsFiddle 中有几个额外的结束 div
标记。
解决方案
$(".close").click(function(){
alert($(this).next().text());
});
工作演示
$(".close").click(function(){
alert($(this).next().text());
});
