Bootstrap 崩溃 - 转到打开项目的顶部？

Question

我正在使用bootstrap折叠功能，但是当我打开一个内容很多的元素，然后打开下一个元素时，它会向下跳转并且不会到达打开元素的顶部。我已经尝试使用如下所示的 scrollto 插件，但它不起作用：

JS：

$(function(){
    $('a.accordion-toggle').click(function(){
        $.scrollTo( this, 500);                                             
    })
});

HTML：

<div class="accordion" id="accordion2">
    <div class="accordion-group heading-left-11">
        <h5 class="accordion-heading row">
            <a class="accordion-toggle span11" data-toggle="collapse" data-parent="#accordion2" href="#collapse1">Austria</a>
            <div class="icon-rt span1">
                <span class="icn"></span>
            </div>

有什么想法吗？

Answer 1

Bootstrap 3 中的事件名称已更改，因此 @bboymaanu's 将无法正常工作。它应该使用 'shown.bs.collapse' 事件。

$(".accordion-body").on("shown.bs.collapse", function () {
    var selected = $(this);
    var collapseh = $(".collapse.in").height();
    $.scrollTo(selected, 500, {
        offset: -(collapseh)
    });
});

新事件是documented here。

Answer 2

我有使用 bootstrap collapse 的滚动条，但代码适用于 WordPress。我引入了你的内容，它有效。 Bootstrap Collapse 有一个显示事件，然后您需要知道要向上滚动的内容的高度。

$(".accordion-body").on("shown", function () {
    var selected = $(this);
    var collapseh = $(".collapse .in").height();
    $.scrollTo(selected, 500, {
        offset: -(collapseh)
    });
});

您可能需要稍微调整一下，但它应该可以工作。

Answer 3

$(".accordion-body").on("shown", function () {
var id = $(this).attr('id');
$('html, body').animate({scrollTop: $('#'+id).offset().top + -50}, 1000);
});
});

简单示例。 “.top + -50”是距元素顶部减 50 像素，允许顶部有一些填充。

Answer 4

这是一个基于其他建议的解决方案：

• 也适用于嵌入式手风琴
• 滚动显示标题
• 仅当屏幕上尚未出现时
• 动画也是如此

代码：

$('#accordion').on('shown.bs.collapse', function (e) {

  // Validate this panel belongs to this accordian, and not an embedded one
  var actualAccordianId = $('a[href="#' + $(e.target).attr('id') + '"').data('parent');
  var targetAccordianId = '#' + $(this).attr('id');
  if (actualAccordianId !== targetAccordianId) return;

  var clickedHeader = $(this).find('.panel > .collapse.in').closest('.panel').find('.panel-heading');
  var offset = clickedHeader.offset();
  var top = $(window).scrollTop();
  if(offset) {
    var topOfHeader = offset.top;
    if(topOfHeader < top) {
      $('html,body').animate({ scrollTop: topOfHeader}, 100, 'swing');
    }
  }
});

Answer 5

$('#accordion').on('shown.bs.collapse', function () {

  var panel = $(this).find('.in');

  $('html, body').animate({
        scrollTop: panel.offset().top
  }, 500);

});

Answer 6

你可以试试这个：

我使用了以下，就像一个魅力：

$("#accordion2").bind('shown', function() {
        var active=$("#accordion_univlist .in").attr('id');
        scrollhere('#'+active);
        $('.closebutton-right').hide(); 
}); 

$('.accordion-heading').click(function () { 
  // Do something if you want to do on click  else ignore this handler.
}

function scrollhere(destination){
    var stop = $(destination).offset().top - 80;
    var delay = 1000;
    $('body,html').animate({scrollTop: stop}, delay);
    return false;
}

它还提供弹跳效果，我喜欢它。
