我的网站上有一个bootstrap手风琴，我试图让页面点击面板底部。目前，如果您单击其中一个图像，您可能不会注意到它会扩展为带有图片下方文字的手风琴。因此，当有人点击图片时，我希望页面点击进入所选面板主体的底部。

您需要做的是连接到手风琴shown.bs.collapse的bootstraps show事件。这样就可以在手风琴完成扩展后获得包装元素的高度。然后，您拥有实现所需目标所需的一切。我已经对代码进行了评论，以帮助您了解我所做的工作。该脚本应放在您的jQuery和Bootstrap JS包含之后。
<script type="text/javascript">
$(document).ready(function() {
// do something when accordion has finished expanding the relevent element
$('.panel-collapse').on('shown.bs.collapse', function() {
// $(this).parent().offset().top gets the top position of the parent element.
// $(window).height() gets the height of the window.
// $(this).parent().height() gets the height of the parent element.
// Subtract the top position of the parent element by the height of the window minus the height of the parent elements height.
var scroll = $(this).parent().offset().top - ( $(window).height() - $(this).parent().height() );
// animate the window scroll by the stored scroll variable.
// The 500 is how long the scroll takes in milliseconds.
$('html, body').animate({
scrollTop: scroll
}, 500);
})
});
</script>
