我使用bootstrap 3来创建一个模态框。我希望autofocus区域有input。我试过jQuery，但我不知道，问题是什么？
JavaScript的：
$('#click').click(function () {
$('input').focus()
});

这可能是硬编码，但添加了一个超时功能来聚焦它 事实上，模态还没有在这里，所以浏览器无法将元素集中在其中。

我已更新您的JSFiddle。使用引导模式窗口时，您可以使用多个custom events。其中一个是shown.bs.modal在完全显示模态后运行（并且您的输入字段是可聚焦的）。请记住，事件将在模态上触发，而不是在打开模态的任何事件上触发。
$('#myModal').on('shown.bs.modal', function () {
$('input').focus();
})
