Question

我想打开一个帮助模式，但根据点击的链接，我需要像在FAQ页面上那样关注特定的锚点。在页面上，我们将在href链接上添加#myAmazingTitle（例如<a href="http://....#myAmazingTitle">FAQ</a>），以便将显示重点放在特定的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模式具有相同的行为。

是否可能以及如何？

此问题为Fiddle。

Answer 1

使用relatedTarget和HTML data-*属性指定目标元素选择器（或锚点），并将此值发送给shown.bs.modal事件的处理程序。请参阅下面的使用示例。

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