Bootstrap Accordion显示点击顶部的内容

Question

JSFiddle https://jsfiddle.net/3ah26cvq/

在JSFiddle中默认情况下HTML是活动的，它包含11个问题。 现在PHP默认情况下它已折叠，当我们点击它时，它将打开，HTML将崩溃。

我的问题是，当我点击PHP时，它显示了PHP的最后一个问题。 在我的例子中，它是Focusing（显示）第11个PHP问题，实际上它应该聚焦（显示） PHP标题因为我们点击了它。 我怎样才能实现它。

与上面的JSFiddle相关

我尝试了3种不同的方式，但没有一种方法有效：

$("#panelForPHP").click(function(){     $("#accordionPHP").focus(); });
$("#panelForPHP").click(function(){     $("#collapsePHP1").focus(); });
$("#panelForPHP").click(function(){     $("#panelForPHP").focus(); });

总之，我点击它应该关注屏幕我该怎么做？

 $("#panelForPHP").click(function(){ $("#accordionPHP").focus(); }); $("#panelForPHP").click(function(){ $("#collapsePHP1").focus(); }); $("#panelForPHP").click(function(){ $("#panelForPHP").focus(); }); 

 .circle { width: auto; height: 23px; text-align:top; float: right; background: #ffff00; color: #fff; color: black; padding-top: 3px; margin-right: -15px; margin-top: -10px; border-bottom-left-radius: 500%; font-size: 11px; padding-left: 7px; padding-right: 7px; } .panel_heading_bg { background-color: #122c5f !important; color: white !important; }

Answer 1

我只是在问题不是第一个时添加一个条件， 因为父标题给出了空格-50px 。 我在<a>添加了一个假类，以帮助我们知道在滚动之前点击的父母......等等

 $("#panelForPHP").click(function() { $("#accordionPHP").focus(); }); $("#panelForPHP").click(function() { $("#collapsePHP1").focus(); }); $("#panelForPHP").click(function() { $("#panelForPHP").focus(); }); $('.panel-heading').on('click', function() { //console.log("TEST TEST : " + $(this).find('h4 a').prop('class')); if ($(this).find('h4 a').prop('class') === 'parents') { //console.log("ok parent"); var target = $(this).find('h4 a').prop('class'); //console.log("target = " + target) /* le sélecteur $(html, body) permet de corriger un bug sur chrome et safari (webkit) */ $('html, body') // on arrête toutes les animations en cours .stop() /* on fait maintenant l'animation vers le haut (scrollTop) vers notre ancre target */ .animate({ scrollTop: $('.' + target).offset().top }, 1000); } else { //console.log($(this).prop('class')); // console.log(typeof parseInt($(this).find('b').text())) if ($(this).find('b').text() != 1 && ($(this).find('h4 a').prop('class') !== 'parents')) { $('html,body').animate({ scrollTop: $(this).offset().top - 50 }, 800); } else if ($(this).find('h4 a').prop('class') !== 'parents') { $('html,body').animate({ scrollTop: $(this).offset().top }, 800); } } }); 

 .circle { width: auto; height: 23px; text-align:top; float: right; background: #ffff00; color: #fff; color: black; padding-top: 3px; margin-right: -15px; margin-top: -10px; border-bottom-left-radius: 500%; font-size: 11px; padding-left: 7px; padding-right: 7px; } .panel_heading_bg { background-color: #122c5f !important; color: white !important; }

Answer 2

你能看到这个小提琴吗？ 我认为这会有所帮助。

 $("#panelForPHP").click(function() { $("#accordionPHP").focus(); }); $("#panelForPHP").click(function() { $("#collapsePHP1").focus(); }); $("#panelForPHP").click(function() { $("#panelForPHP").focus(); }); $('.panel-heading').on('click', function() { $('html,body').animate({ scrollTop: $(this).offset().top }, 800); }); 

 .circle { width: auto; height: 23px; text-align:top; float: right; background: #ffff00; color: #fff; color: black; padding-top: 3px; margin-right: -15px; margin-top: -10px; border-bottom-left-radius: 500%; font-size: 11px; padding-left: 7px; padding-right: 7px; } .panel_heading_bg { background-color: #122c5f !important; color: white !important; }
