嘿，我正试图修复一个用于移动设备的标签页面。当用户点击圆形圆圈时，它应该是文本。比你点击＆＃34; Terug naar keuzemenu＆＃34;你应该回到圈子（选项卡的导航）。但是，当我第一次点击时我想转到其他标签时，他没有滚动到文本部分，但第二次他没有。所以我必须点击两次，但无法弄清楚原因。

答案 0 :(得分：1)
这是因为父类.check-up-overview上的点击处理程序。
当您单击圆圈时会导致双触发，这说明您必须单击两次以绑定scrollTop()功能的原因。
这里JS代码发生了变化：
$(document).ready(function() {
$('a[href^="#"]').on('click', function(e) {
if (!$(this).parents('.check-up-overview').hasClass('xx_active')) {
var sCurrent = $(this).parents('.check-up-overview').attr('id');
var sPrevious = $('.xx_active').attr('id');
$('.xx_active').removeClass('xx_active');
$('.' + sPrevious).removeClass('bike-show').addClass('bike-hide');
$(this).parents('.check-up-overview').addClass('xx_active');
$('.' + sCurrent).removeClass('bike-hide').addClass('bike-show');
}
if($(window).width() < 768){
e.preventDefault();
var target = this.hash;
$target = $(target);
$('html, body').animate({
'scrollTop': $target.offset().top //no need of parseInt here
}, 900, 'swing', function() {
//window.location.hash = target;
});
}else{
e.preventDefault();
}
});
});
