Report designer detail band 包含 Add band 按钮，它应该在 detail 面板之前和之后立即添加新面板。
$parentpanel = $this.parents(".designer-panel:first");
用于查找父面板和 .prepend()/append() 添加新面板。
面板被添加为细节面板的子元素。 如何在相同 DOM 级别的详细信息面板之前和之后添加面板，例如示例 html 中的组页眉和页脚面板。
元素可能应该添加到 $parentpanel.parent() 元素列表之前和之后 $parentpanel 元素。
在 jQuery 中有一些选择器或追加命令吗？
$(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}' +

试试 jQuery 的 before , after功能。或者 insertBefore , insertAfter
你也可以用
$this.closest(".designer-panel");
代替
$this.parents(".designer-panel:first");
参见 closest
