Question

点击我的手风琴表中的随机行后，我想将我的网页内容向下滚动到所点击行的顶部偏移位置。

我该怎么做？

P.S。

我的尝试如下

点击一行时抓住
当扩展以指南here
滚动指南here

虽然这会将很多处理程序堆叠到我的手风琴表中。所以我的问题是我们如何才能抓住事件AFTER a row is clicked and its expansion is finished？

使用此示例它可以正常工作。

＆＃13;

$(document).ready(function(){

$('#collapseExample').on('shown.bs.collapse', function(e) {
	//snippet.log("shown");
	var scroll_tab_position = $('#'+$(e.target).attr('id')).prev().offset().top;
		$('html, body').animate({
			scrollTop: scroll_tab_position
		}, 2000);
    }).on('show.bs.collapse', function(e) {
      //snippet.log("show");
    });
	

});
