Question

我正在使用http://getbootstrap.com/javascript/#modals-related-target，但是，当我在自己的项目中使用代码时，该函数不起作用。我对此很新，所以它可能很简单。

这是我的代码：http://hastebin.com/comikucidi.xml

谢谢。

编辑：刚刚创建了一个全新的文档并复制了引导页面。该功能仍无法正常工作

Answer 1

您尝试将处理程序附加到不存在的ID，尝试使用模态的ID：

$('#delete').on('show.bs.modal',

而不是#exampleModal。

编辑：

您还应该添加

$(document).ready(function () {
  //your code here
});

围绕代码，在正确创建元素后附加处理程序。

Answer 2

将脚本放在jQuery库调用的末尾，如下所示：

jQuery（Bootstrap的JavaScript插件所必需的） [这里]

$('#exampleModal').on('show.bs.modal', function (event) {...}

如果你这样做，那就有效了！

基于触发按钮改变模态内容
