7 html javascript jquery twitter-bootstrap
我想知道为什么我的Bootstrap 4模态不起作用.任何线索？我从Bootstrap 4网站(http://v4-alpha.getbootstrap.com/components/modal/#live-demo)复制并粘贴.另外,我添加了他们说的js.
请在下面找到代码.
谢谢
我查过了其他帖子,但我没有运气
$('#myModal').on('shown.bs.modal', function() {
$('#myInput').focus()

</html>您的代码段中有拼写错误(最后未使用});),但最重要的是,切换按钮的目标是错误的模式ID.确保data-target您要定位的模态的ID:
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#myModal">
Launch demo modal
</button>
演示:
$('#myModal').on('shown.bs.modal', function() {
$('#myInput').focus()
