除了在 stackoverflow 上折叠 Bootstrap 可折叠之外的所有工作，我将不胜感激一些建议。

当any opened item是clickedto 时collapse，其类按以下顺序变化：panel-collapse collapse in> panel-collapse collapsing> panel-collapse collapse in。在正确的顺序中，它应该导致panel-collapse collapse collapsed. 这还没有解决。问题是它collapse被调用了两次。

对此有什么解决方案，以便我可以将其用作模板的一部分？

更新：只有一个panel-group可以独占打开。现在通过删除解决data-parent了这个问题，它现在允许同时打开多个面板。

我添加了登录bootstrap.js（第 608-628 行）：

  // COLLAPSE DATA-API
  // =================

  $(document).on('click.bs.collapse.data-api', '[data-toggle=collapse]', function (e) {
    var $this   = $(this), href
    var target  = $this.attr('data-target')
        || e.preventDefault()
        || (href = $this.attr('href')) && href.replace(/.*(?=#[^\s]+$)/, '') //strip for ie7
    var $target = $(target)
    var data    = $target.data('bs.collapse')
    var option  = data ? 'toggle' : $this.data()
    var parent  = $this.attr('data-parent')
    var $parent = parent && $(parent)

    console.log("A",data);
    if (!data || !data.transitioning) {console.log("B1");
      if ($parent) { console.log("B2");
          $parent.find('[data-toggle=collapse][data-parent="' + parent + '"]').not($this).addClass('collapsed')
      }
      console.log("B3",$target.hasClass('in'));
      $this[$target.hasClass('in') ? 'addClass' : 'removeClass']('collapsed')
    }
    console.log("C", option);
    $target.collapse(option)
    console.log("D");
  })

结果日志：

a)collapse第一次按下时，它看起来很乱

bootstrap.js:622 A undefined
bootstrap.js:623 B1
bootstrap.js:624 B2
bootstrap.js:627 B3 false
bootstrap.js:630 C Object {toggle: "collapse", bind: "text:displayLabel, attr:{href:idhash}"}
bootstrap.js:632 D
bootstrap.js:622 A Collapse {$element: jQuery.fn.jQuery.init[1], options: Object, transitioning: 1}
bootstrap.js:630 C toggle
bootstrap.js:632 D

b)collapse任何其他时间按下时

bootstrap.js:622 A Collapse {$element: x.fn.x.init[1], options: Object, transitioning: 0}
bootstrap.js:623 B1
bootstrap.js:624 B2
bootstrap.js:627 B3 true
bootstrap.js:630 C toggle
bootstrap.js:632 D
bootstrap.js:622 A Collapse {$element: jQuery.fn.jQuery.init[1], options: Object, transitioning: 1}
bootstrap.js:630 C toggle
bootstrap.js:632 D

正确的输出应该是：

a)collapse第一次按下时

bootstrap.js:622 A undefined
bootstrap.js:623 B1
bootstrap.js:624 B2
bootstrap.js:627 B3 false
bootstrap.js:630 C Object {toggle: "collapse", bind: "text:displayLabel, attr:{href:idhash}"}
bootstrap.js:632 D

b)collapse任何其他时间按下时

bootstrap.js:622 A Collapse {$element: jQuery.fn.jQuery.init[1], options: Object, transitioning: 0}
bootstrap.js:623 B1
bootstrap.js:624 B2
bootstrap.js:627 B3 (true or false)
bootstrap.js:630 C toggle
bootstrap.js:632 D

完整代码：

var confItems = {};
var childrenLength = 2;
confItems["children"] = new Array(childrenLength);
for (var i = 0; i < childrenLength; i++) {
  confItems.children[i] = {};
  confItems.children[i]["idhash"] = "#col-" + (i + 1);
  confItems.children[i]["id"] = "col-" + (i + 1);
  confItems.children[i]["displayLabel"] = "Item " + (i + 1);
  confItems.children[i]["children"] = new Array(childrenLength);
  for (var j = 0; j < childrenLength; j++) {
    confItems.children[i].children[j] = {};
    confItems.children[i]["idhash"] = "#col-" + (i + 1) + "-" + (j + 1);
    confItems.children[i]["id"] = "col-" + (i + 1) + "-" + (j + 1);
    confItems.children[i].children[j]["displayLabel"] = "Item " + (i + 1) + "." + (j + 1);
    confItems.children[i].children[j]["children"] = new Array(0);
  }
}
var viewModel = function() {
  this.tree = ko.observable(confItems);
};
ko.applyBindings(new viewModel());

一个便宜的解决方案是修改bootstrap.js和删除'[data-toggle=collapse]'.

我仍在寻找造成这种情况的原因以及发生了什么，所以我不必求助于修改bootstrap.js. 即使在修改之后，也会collapse被调用两次。

对此我还没有找到答案。

  // COLLAPSE DATA-API
  // =================

  $(document).on('click.bs.collapse.data-api', function (e) {
    var $this   = $(this), href
    var target  = $this.attr('data-target')
        || e.preventDefault()
        || (href = $this.attr('href')) && href.replace(/.*(?=#[^\s]+$)/, '') //strip for ie7
    var $target = $(target)
    var data    = $target.data('bs.collapse')
    var option  = data ? 'toggle' : $this.data()
    var parent  = $this.attr('data-parent')
    var $parent = parent && $(parent)

    console.log("A",data);
    if (!data || !data.transitioning) {console.log("B1");
      if ($parent) { console.log("B2");
          $parent.find('[data-toggle=collapse][data-parent="' + parent + '"]').not($this).addClass('collapsed')
      }
      console.log("B3",$target.hasClass('in'));
      $this[$target.hasClass('in') ? 'addClass' : 'removeClass']('collapsed')
    }
    console.log("C", option);
    $target.collapse(option)
    console.log("D");
  })
