面板作为详细信息面板子元素添加。
如何在相同DOM级别的详细信息面板之前和之后添加面板，如示例html中的组页眉和页脚面板。



元素应该添加到 $ parentpanel.parent（）元素列表之前和之后 $ parentpanel 元素。



在jQuery中有没有一些selector或append命令？



  $（function（）{var startpos，selected = $（[]），offset = {top：0，left：0}; $（'＃designer-detail-addband'）。 '，function（）{var $ this = $（this），$ parentpanel = $ this.parents（。designer-panel：first）; $ parentpanel.prepend（'< div class =panel designer-panel >'+'< div class =panel-body designer-panel-bodystyle =height：1px>'+'< / div>'+'< div class =bg-warning >'&';'< div class =panel-footer>< i class =glyphicon glyphicon-chevron-up>'+'< / i>群组{0}：< span id =band {0} _exprcontenteditable =true>groupexpression< / span>'+'< / div>< / div>< / div ;'）; $ parentpanel.append（'< div class =panel designer-panel>'+'< div class =panel-body designer-panel-bodystyle =height：1px>< / div> ;'+'< div class =bg-warning>'+'< div class =panel- footer>< i class =glyphicon glyphicon-chevron-up ; / i> Group footer {0}'+'< / div>< / div>< / div>'）; }）; $（。designer-panel-body）。droppable（{accept：.designer-field}）; $（。designer-field）。draggable（{start：function（event，ui）{var $ this = $（this）; if（$ this.hasClass（ui-selected））{selected = $ .ui-selected）。each（function（）{var el = $（this）; el.data（offset，el.offset（））;}）;} else {selected = $（[]） ; $（。designer-field）。removeClass（ui-selected）;} offset = $ this.offset（）;}，drag：function（event，ui）{// = ui.position.top  -  offset.top，dl = ui.position.left  -  offset.left; selected.not（this）.each（function（）{var $ this = $（this）; var elOffset = $ this .data（offset）; $ this.css（{top：elOffset.top + dt，left：elOffset.left + dl}）;}）;}}）; $（。panel-resizable）。resizable（{minWidth：100％，maxWidth：100％，minHeight：1}）;}）

解决方案

尝试使用jQuery的之前，函数。或，



也可以使用

  $ this.closest（。designer-panel）;

而不是

  $ this.parents（。designer-panel：first）;

请参阅


Report designer detail band contains Add band button which shoud add new panels immediately before and after detail panel.

$parentpanel = $this.parents(".designer-panel:first");

is used to find parent panel and .prepend() / append() to add new panels.

Panels are added as Detail panel child elements.How to add panels before and after Detail panel in same DOM level like group header and footer panels in sample html.

Elements should probably added to $parentpanel.parent() element list before and after $parentpanel element.

Is there some selector or append command in jQuery for this ?

$(function() {

  var startpos,
    selected = $([]),
    offset = {
      top: 0,
      left: 0
    };

  $('#designer-detail-addband').on('click', function() {
    var $this = $(this),
      $parentpanel = $this.parents(".designer-panel:first");

    $parentpanel.prepend('<div class="panel designer-panel">' +
      '<div class="panel-body designer-panel-body" style="height:1px">' +
      '</div>' +
      '<div class="bg-warning">' +
      '<div class="panel-footer"><i class="glyphicon glyphicon-chevron-up">' +
      '</i> Group heade {0}: <span id="band{0}_expr" contenteditable="true">"groupexpression"</span>' +
      '</div></div></div>');

    $parentpanel.append('<div class="panel designer-panel">' +
      '<div class="panel-body designer-panel-body" style="height:1px"></div>' +
      '<div class="bg-warning">' +
      '<div class="panel-footer"><i class="glyphicon glyphicon-chevron-up">' +
      '</i> Group footer {0}' +
      '</div></div></div>');

  });

  $(".designer-panel-body").droppable({
    accept: ".designer-field"
  });

  $(".designer-field").draggable({
    start: function(event, ui) {
      var $this = $(this);
      if ($this.hasClass("ui-selected")) {
        selected = $(".ui-selected").each(function() {
          var el = $(this);
          el.data("offset", el.offset());
        });
      } else {
        selected = $([]);
        $(".designer-field").removeClass("ui-selected");
      }
      offset = $this.offset();
    },

    drag: function(event, ui) {
      // drag all selected elements simultaneously
      var dt = ui.position.top - offset.top,
        dl = ui.position.left - offset.left;
      selected.not(this).each(function() {
        var $this = $(this);
        var elOffset = $this.data("offset");
        $this.css({
          top: elOffset.top + dt,
          left: elOffset.left + dl
        });
      });
    }
  });

  $(".panel-resizable").resizable({
    minWidth: "100%",
    maxWidth: "100%",
    minHeight: 1
  });
})
.panel-resizable {
  min-height: 1px;
  overflow: hidden;
  margin: 0;
  padding: 0;
}
.designer-field {
  border: 1px solid lightgray;
  white-space: pre;
  overflow: hidden;
  position: absolute;
}
.designer-panel-body {
  min-height: 1px;
  overflow: hidden;
  margin: 0;
  padding: 0;

.panel-footer {

解决方案

Try jQuery's before, after functions. Or insertBefore, insertAfter

Also you can use

$this.closest(".designer-panel");

instead of

$this.parents(".designer-panel:first");

See closest
