html - 指向 Bootstrap 模式打开的 anchor

Question

我想打开一个帮助模式，但是根据点击的链接，我需要像在常见问题解答页面上那样关注特定的 anchor 。 在页面上，我们将在 href 链接上添加 #myAmazingTitle(例如 <a href="http://....#myAmazingTitle">FAQ</a> 以将显示集中在特定的 dom 元素上。

<h1>My first title</h1>
<h1 id="myAmazingTitle">My Amazing Title</h1> <== Display will be focused on this title
....

我希望使用 Bootstrap 模态具有相同的行为。

这可能吗？如何实现？

这是 Fiddle对于这个问题。

Answer 1

使用relatedTarget和 HTML data-* 属性来指定目标元素选择器(或 anchor )并将此值发送到 shown.bs.modal 事件的处理程序。请参阅下面的用法示例。

$('#exampleModal').on('shown.bs.modal', function(e) {
  var recipient = $(e.relatedTarget).data('focus');
  $(this).find( recipient ).focus();  
});
