我正在处理一个包含每行隐藏详细信息的表。表行由Bootstrap手风琴制成。 手风琴行和隐藏的细节工作正常但是在切换[折叠/展开]时更改V形图标的JS无法正常工作。它应该只更改单击行上的V形图标，但目前它会更改所有行的V形图标。
我已经阅读了一些关于我的问题的相关帖子并且已经尝试了所有这些但我无法让它工作。我缺少什么？

将您的.parent()更改为.prev()或.prev('tr')
$('tr').on('shown.bs.collapse', function(){
$(this).prev('tr').find(".fa-plus-square").removeClass("fa-plus-square").addClass("fa-minus-square");
}).on('hidden.bs.collapse', function(){
$(this).prev('tr').find(".fa-minus-square").removeClass("fa-minus-square").addClass("fa-plus-square");
});

这应该有效：
$(".accordion-toggle").on("click", function () {
if($(this).find(".fa").hasClass("fa-plus-square")) {
$(this).find(".fa").removeClass("fa-plus-square").addClass("fa-minus-square");
} else {
$(this).find(".fa").removeClass("fa-minus-square").addClass("fa-plus-square");
}
});
