我有一个div数组和一个函数，用于关闭div中的扩展部分。
我还可以通过函数中的动作侦听器事件来识别我所在或单击的div（数组对象）。
我试图在单击（关闭）时滚动到当前部分的顶部。
但是，当我尝试滚动到告诉我当前数组索引的var顶部时，出现以下错误。
TypeError：n.offset不是函数
有人知道如何更改我的代码以使单击（关闭）滚动到当前div索引的顶部吗？
我的JavaScript
_bindShowLess = function () {
var _showLess = _sectorPageStrengths.find('.view-all-sectors-btn.less');
_showLess.on('click', function () {
var sliders = [].slice.call(document.getElementsByClassName("sectorpage-strengths"));
sliders.forEach(function (element, index){
element.addEventListener("click", function(){
console.log("array" +index + "!");
});
});
$('html, body').stop().animate({
scrollTop: sliders.offset().top
}, 700);
// $('html, body').animate({
// scrollTop: _sectorPageStrengths.offset().top
// }, 700);
});
};
